Ok, I didn't come back as soon as I had planned to post my observations but my three Lhasa's have had two doses of the Comfortis and have had NO ill effects. They are completely flea free and we have had no loose stools, no lethargy, no nausea, nothing. My poor pooche has even began to grow her hair back where the hot spots were. Maybe different breeds react differently to this med but my boy & girls are doing great!

My Aussie Mix had a bad reaction to Comfortis and I'm not giving her this drug again. About 5 hours after I administered Comfortis to her she was unable to walk. Couldn't get up off of the floor, couldn't jump on the bed, couldn't move her back legs at all. They were like spaghetti. At first I thought she had just done something to strain her muscles (she's 11), so chalked it up as coincidence.

The second time I gave her the pill (about two months after the first dose), she had exactly the same symptoms. I asked my vet about it but he said he found it highly unlikely that the Comfortis would be causing this. But don't you think it's a bit of a coincidence that the only two times in her life she has ever had these symptoms was shortly after taking Comfortis?

So I'm erring on the side of caution and not giving her any more. I have three other dogs who also have mild flea allergies. I try as many natural routes as possible (flea combing every night, lavender / pennyroyal / cedar spray, vinegar spray on them and around their pet bed areas, nematodes sprayed on the lawn 3 to 4 times a year). I'm not a fan of diatomaceous earth. Because its made from fossilized shells, the particles are like tiny shards of glass which - if inhaled - can really mess up your dog's respiratory tract. And since they use their noses so much, I don't want to risk having them inhale this stuff.

Meanwhile, I'm back to the drawing board myself. I'll continue with my summer regimen of baths, combing, etc. in hopes that it wards off the fleas enough to keep my dogs comfortable and sane. I don't like pesticides. Never did, never will. There has to be an alternative out there that won't harm our pets, OR us, in the long run.

WHAT A SAVING GRACE! I DID MUCH RESEARCH ON THIS FOR ABOUT 10 DAYS, AND I READ ALL THE STORIES GOOD AND BAD, I HAD TO DECIDE IF GIVING THIS TO MY DOXIE WOULD BE GOOD OR BAD. I AM AT MY WITS END WITH FLEAS, MY DOXIE MAGGEY SUE CAME FROM TEXAS TO MY STATE WASHINGTON, SHE WAS COVERED IN FLEAS WHEN I PICKED HER UP AT THE AIRPORT, I GAVE HER A BATH AND PUT FRONT LINE ON HER(MIND YOU THIS WAS A YEAR AGO) I HAVE BEEN BATTLING FLEAS EVER SINCE!!!!!! NOTHING WORKED, I MEAN NOTHING!!!!!!!! I HAVE TRIED IT ALL, I FINALLY CHOOSE TO GET COMFORTIS THIS EVENING I DID EXACTLY WHAT THE VET SAID GIVE ON A FULL TUMMY, LESS THEM 3 HOURS LATER ALL THE FLEAS WERE DEAD ON HER!!!!!! DEAD ALL DEAD! SHE HAD NO EFFECTS WHAT SO EVER AND I AM SO HAPPY! I FINALLY FEEL LIKE I AM ON THE ROAD TO GETTING RID OF THESE DARN FLEAS! SO HAPPY AND COMFORTIS IS MY SAVING GRACE AND MY DOGS TOO!

We have 4 mastiffs and used Comfortis a few days ago. It did get rid of anything they might of had but the the side effects of one of our dogs was and still is HORRIBLE. She cant control her back legs, she has been vomiting, her pupils are a whitish looking color. She have been drinking water and still wag her tail but she is the worst. I WILL NEVER EVER use this stuff again.

I have a 1 year old fox terrier. I read through most of the postings on the site before giving her the comfortis pill...while I was hesitant to give it to her due to the side effects that others said their dogs experienced I felt like it would be the best option to get rid of her fleas. While the pill worked very well and very quick, the side effects were terrible! Before giving her the pill, she was a VERY active (running, playing constantly), fun, and loving dog. I gave her the pill at the beginning of September and she still has bad side effects from it. Some days she acts normal other days she gets very easily aggresive with people and also my other animals (which she has always gotten along with before) she gets to the point where she has to be put away by herself so she doesn't fight the other dogs. She's also always very tired and always thirsty. I'm hoping these effects on her will wear off. So while the comfortis did work really well to get rid of the fleas and quickly I will never give her this pill again...it just not worth the side effects that come along with it.

I have read all the posts and I do think dogs could have reactions to any type of drug. Even people can with all the drugs people take for health reasons. I just wanted to post my experience here with Comfortis. I had never hear of it before yesterday when I called my vet and explained the situation I was having with fleas and how I have spent so much money on soaps and sprays and dusting powders and how nothing was working. I have two boston terriers and a rottie. The two bostons have had reactions to the flea products like frontline to the point I had to bring them both to the vets for treatment. So I wonât use them again. I have never had fleas to where I have spent over two months trying to get rid of them. Usually a couple flea baths and they are gone. This year has not been the case. Well my vet gave us Comfortis and I gave it to them last night. None of my dogs have had reactions (even my old boston who has health issues). All are scratching less (which I feel the scratching they are doing now is do to the old bites). My other boston slept all night which he hasnât done for quite a while. I havenât woke up to my Rottie scratching all night next to my bed. We will see how it does later in the month. I will use this product again. We are having snow already so I am hoping I wonât need another dose until next summer.

I suggest everyone read these links, considering these products have been out for a number of years we are now getting these warnings about two well used flea products and how dangerous they can be.
Together with the practice of giving vaccination boosters which are NOT NEEDED, it has been well documented that scientific studies which came out with guidelines mentioned in the vaccination article stating there is no need to repeat vaccinations since immunity from a puppy vaccination course lasts for 9 years or the lifetime of the dog or cat WITHOUT re-vaccinating.
Read these links, we are killing our pets with overdose of pesticides, vaccinations and commercial pet food. below links that pet owners should read about why pet food kills our pets.

have been using comfortis for a couple of years.we live in florida with 2 large dogs,a weim and a giant schnauzer.we would recomend comfortis.

In central florida there is a bad flea problem year round. Nothing else on the market works for more than a few days. We've been using Comfortis for 6 months now. We grind the pill and put it in the dogs wet food. We've seen no side effects, our dog also has no more fleas. Will continue to use Comfortis whatever the price.

I have 3 dogs (1 tiny, 1 middle and 1 biggish)and have used Comfortis twice. It really works and does what it says it will.It is amazingly effective. BUT...The first time all ok - the middle size dog did have a seizure at night but we were uncertain about what caused it - did not connect it with Comfortis (the leaflet says ne adverse reactions. The second time,(several months later) just a week ago and within hours of taking Comfortis, the middle dog had a severe seizure - rigidity, incontinence, spasms, panting (very distressful to watch) lasting half an hour. The next day she couldn't walk or stand up and, a week later still is very unsteady on her feet, falling over and very cautious. We hope she may only have pinched a nerve in her back or slipped a disc during the seizure and will fully recover but we will NEVER give her Comfortis again. However, we will use it on the other dogs.
The lesson; as with every medication, there will be individual reactions so be aware and make the decision to use it or not based on the risks/benefits. I'm sure the manufacturers know there have been some bad reactions so it is very irresponsible of them to say in their leaflet that there are "No contraindications". They just need to be honest rather than evasive. It is a good product for most dogs but owners should be aware that there are adverse reactions and be given credit for being able to make a decision based on full disclosure.

Comfortis is the best thing I have ever come across for our dogs. We have been battling fleas for 2 years now. We have spent thousands of dollars to have our house and yard professionally treated, used frontline plus on the dogs, even started flea bathing weekly as well as combing daily. Our dogs would do nothing but lay around and itch, whine and actually rip out their fur to the point that they were bleeding messes. I did not know what else to do rid ourselves of this problem. The Vet would continually tell me that I needed to treat my dogs monthly with frontline as well as the home and yard, and I in return told him that we were doing all that.

Then last November we were told about comfortis, which is slightly cheaper than frontline in our area. So I figured gievn everything we have tried might as well try this.

Within a day of giving them this pill, they were happy not itching or whining. I have used it monthly since November 2010. I just gave them their 4 dose of this and the only side affect we have had is NO FLEAS!!!!! I would recommend to anyone, I have happy dogs again and it took us 2 years to find that magic pill that would make them happy. Go get it it is more than worth it for the relief your dog and you will get.

BEWARE, BE VERY CAREFUL
We live on the the East Coast of NSW Australia. Recently unbeknownst to us, we visited a flea infested house with our 3 dogs and since then we've got fleas :( Prior to this we were flea free. We feed our dogs on a BARF diet and only use natural remedies and medicines.

Recently a friend mentioned how great Comfortis has been for his dogs, he's been using it for a few months now. I was tempted with the product and thought to do a lttle research before trying it out.

When I google comfortis only the good reviews seem to come up. I was a little suspicious and entered keys words such as adverse reactions and the like. What I've found so far is disturbing. Many of the symptoms that people have described are very similar to pancreatitis. I lost 2 old dogs to this horrible disease and know the symptoms very well. Please note that my previous dogs were not fed BARF and it was their illness that made me look into a better diet.

Some of symptoms I refer to are vomiting, starting with white, then yellow, then pink. Lethargy, loss of coordination, excessive thirst and weight loss. When pancreatitis strikes it usually meant hospitalisation for several days and eventaully death.

Having read about similar reactions after people using comfortis on their dogs I have decided not to use it. I will persevere with food grade diatomaceous earth, neem oil, rosemary rinses etc, but I WILL NOT take the chance with ,my beloved dogs.

I found another site that people might like to read. The only reason I'm posting this is that if it wasn't for people posting their experiences I could well be one of the unlucky one, a chance I would never ever take with my dogs.
http://www.viewpoints.com/Comfortis-reviews?N[]=28+4294331966

I'm very sorry for those people who have lost or nearly lost their beloved dog.

I've been using comfortis for about a year and half now, I've had no trouble with any of my dogs with any kind of side effects. I've taken them to my mother ranch and let them run around with the other dogs, when we come home they have no fleas or ticks. I use to use frontline, but had to spray every couple of weeks when we go to the ranch, with the comfortis I give them their pill every other month and they are flea free. I would recommend Comfortis to anyone who have dogs.

If your yard is infested with fleas, the best and natural way to get rid of fleas and ticks is use BANANA PEELS, don't laugh its true, I've been using banana peels for over 20 years and it works. What you do is buy bananas at your local grocery store and peel them, save the fruit for whatever you want, I make bread,cakes,pudding or pies. My family knows when I treat my yard...LOL. What you do next is toss one banana peel per five or ten square yards of your yard, after a couple of days you will notice that your yard is fleas free, to keep my yard clean and free I treat my yard twice a year to make sure if any animals carring fleas come in to my yard they are taken care off. Plus you make your family happy with desserts too..LOL

Hope this information was helpful to you.

Unbelievable! I'm just learning now the reason why my 11 yr/old female Westie almost died in March of 08. I'm in central FL and my second Westie's been treated for allergies to just about everything (didn't need an expensive allergy test to figure that out either).

The usual treatments with prednisone and sometimes antibiotics were VERY temporary. Being my 2nd Westie I already knew to go as natural as possible with food and flea treatments. But sometimes you have to use the big guns. Back in March 08 I ended up at an expensive skin specialist. She did a skin biopsy as opposed to the useless skin scrape done my most vets and found she had demodectic mange and flea excrements. So she gave her a Comfortis pill and gave me Ivermectin liquid. After 2-3 days my dog was falling off while walking and totally disoriented and clingy. I took her to emergency clinic (of course she gets sick on a weekend). Vet said stop all meds and call specialist first thing Monday morning. I don't think the specialist knew about the interaction problem then, but she put her on Interceptor for 5 months and my Westie was perfect for 2 years.

I never gave her Comfortis monthly (vet don't like this). Only at first sign of scratching(always cut in 4, mixed with can food). Our heavy flea season coincide with pollen season; Oct (trees shedding) and Feb through May (pollen etc) Whenever the temperature hovers between 70F-85F day time.

I also spray my yard and surroundings with the inexpensive flea/tick citrus shampoo from Hartz for $2-$3 at Walmart. Use hose attachement container, pour whole bottle of shampoo plus water and spray. Pray it doesn't rain for a few days and don't water your lawn either. Don't let your pets walk on ANY type of pesticide for 4-5 days. Also, get rid of your carpets. Best is laminate floors with disposable/washable area rugs.

My Comfortis dilemma is, I've been trying to narrow down on a new situation that started to occur with my Westie. At those time of the year mentioned above she has a YEAST overgrowth flair up. Her skin gets greasy, smelly and full of brown debris and dark areas where the most greasy. I've been doing extensive research on Yeast Imbalance here http://tinyurl.com/24792su

Turns out MANY dogs diagnosed with allergies have actually Yeast overgrowth and whatever treatments used to treat allergies actually PROVOQUE a yeast overgrowth which cause more scratching, biting and paw licking. What a catch 22!

Main causes of all this is, a weaken immune system caused by immune system suppressants like vaccinations (I only vaccinate this dog when younger), pesticides (who can avoid them totally?) and prednisone (which the specialist said never to give her again) among other things.

Did Comfortis (dose of insecticide) suppressed my Westie's immun system so much so that it triggered a yeast overgrowth AND/OR pollens and other allergies caused the flair up?

In any event I ordered natural Flea Treats and may or may not give her Comfortis again unless a bad flea infestation.

Also looking into this new food by Wysong Epigen; it's starch free.

My conclusion on Comfortis is; every dog is different. If a dog's immun system has been compromised in anyway shape or form by other triggering agents mentioned above, proceed carefully.
Ordering online is cheaper but now vets tell me "Oh well it's been a while since we haven't seen your dog and would like to do exam (take my money again) before we can allow the prescription."

Also very useful to treat skin ailments; most effective for me are:
1)Bathe with Malaseb shampoo (DO leave on 10 min), rinse thorougly, then pour over dog (and leave on) a suiting solution of 2-3 tbs of baking soda diluted in a gallon of warm water. DO NOT submerge dog, the parasites will gather around the neck area. Best is a dog rinsing hose in a shower.

2) Apply ANIMAX ointment on hot spots. (best ointment out of many) cheapest at vetdepot.com

3) Add immun booster supplement to dog food. Solid Gold Seameal is good but proceed slowly with SMALLER dosage or you'll come home to a house full of diarrhea.

Keeping finger crossed, for May is always the worst for fleas that I won't have to use Comfortis but since she'll be on Seameal let's hope and pray for no adverse reaction.

We have 13 dogs and have also had a very bad flea problem. Last fall we decided to use Sentry Natural Defense, and it worked. We used it all winter, even when the fleas weren't as bad, and our short-haired dogs are still mostly flea free. Now that it is getting warmer, our long-haired dogs do have fleas again, but nothing like before. We just have to treat them more often. With this many dogs, Natural Defense doesn't seem to kill all fleas, but other people with fewer dogs say that it does. The great thing about this stuff is that it is supposed to be all natural ingredients so your dogs shouldn't have any adverse reactions to it, and it is cheap. We order it from JeffersPet, and it is $8.49 for three months, no matter what size dog you have. We have been thinking about trying Comfortis for the long-haired dogs, but have been really worried about giving it orally. When it first came out, we asked our vet about it and they didn't recommend it, but they are now selling it because another vet down the road from them is selling it. After reading these posts, I know that I am not willing to put my dogs in jeopardy just to get rid of the fleas that are left. I recommend everybody try Natural Defense. The only bad thing about Natural Defense is that is does have a bad smell, but that goes away after a few hours.

It's very expensive, yes... but I was desperate with my poor dog that had a horrible flea infestation for over a year, and I spent so much money on other medicines and drops that I was relieved when my vet told me about a pill that kills the fleas within 30 minutes. Here's what's so great about Comfortis over other flea medicines: The fleas bite your dog, then die. Other fleas hop on your dog from your house... bite your dog, then they die. Over a period of a week, all the eggs have been hatched, and when they bite your dog, they die too. It not only rids your dog of fleas... it rids your house of them too. I gave it to my dog for 6 months, and never saw a flea, even though we have a cat as well. I did not buy more because of the cost, and now, we are infested again... cat and dog. It would be great if Spinosad was in a cheaper form, but as of yet, I have not found it.

My dog hates it, but she has no fleas! I take a table out of the sealed package, and she goes into the next room. Can't disguise it in cheese or any other tasty treat...she can detect it. So, I have to poke it down her throat, and then give her a treat. She has had one episode of vomiting following administration...it was right at an hour later, so not really sure if it was related to the Comfortis or not. Will see if it happens again next month. My Vet did not recommend re-dosing her since it had been in her system for an hour.

it is amazing starts killing fleas in 30 min. and keeps them off it also attracts the flea in your home and yard onto your dog and kills them.. it does work for ticks and is easy one pill thats it you dont have to bathe your dog wait a day then put the frontline on and watch it get all over everything..

My shih-tzu and I moved from Virginia to Florida in September. He had never had a flea problem before til we came down here. Within a month, he was scratching incessantly and driving us both crazy. I called the vet and asked if there was something, other than Frontline,that they recommended and they told me Comfortis. He has been on it for 2 full months and has not had a problem since.

I absolutely love the product. I was using Frontline last summer, plus about $150 a month of sprays. I still had the worse flea infestation I had ever seen. I was spraying the yard, the house and them daily. I gave both dogs Comfortis, and the fleas were gone within hours. I didn't have fleas for the rest of the year- about three months until it got cool. I figured I saved about $120 a month.

I have lived in my house in Madisonville, TN going on 6yrs and ever since I moved here my Shih Tzu started have a bad flea problem. I called the vet about this after I spent hundreds of dollars on flea products that help some, but then they came back. Everytime I took him to be trimmed I also had them to give him a flea dip. So I got fed up with the fleas, that is when I called the vet to see what can be done about the fleas and they recommended the Comfortis. I started giving my dog this pill and now he is flea free. He is in better spirits now since the fleas are gone. Where I live there is a lot of stray dogs that come in and out of our yard everyday and this is why he never had fleas before now.

my dog is 12lbs.icant afford a big about of money to get rid of the fleas.what is the best deal for comfortis 3,6,1yr. supply

I have been using this on my Wolfhounds for a few years now... Love it and it's very important that you give this to them after they've eaten a good meal... OR as some of you have written your dog will vomit. I just can't imagine that if someone actually followed the specific directions that both of they're dogs would vomit, sounds to me like they didn't wait till the food had settled on they're stomaches. I've heard of some very WEAK dogs having issues with taking comfortis, but to have 2 dogs in the same house have an issue, I think I'd chalk that up to USER ERROR.

Also, please note, not sure if this works for everyone else, but I only use the comfortis during the flea season, don't seem to need to use it during the winter, and I only give it to my dogs every 3 months and it works very well for us. We have a 10 acre farm so there is lots of places for my dogs to pick up a flea. So you might want to try using it every other month and see how that works for you and then move it out another month and see if that doesn't help keep the fleas under control.

We have had excellent luck with comfortis. We 8 rescues-all different breeds &/or mixes and none of them have suffered adverse effects as long as we feed a small meal with the tablet. It makes them violently ill if you dose on an empty stomach. None of them like this pill-it is supposed to be similar to a beef flavored treat.....no. They can detect it in food but it works so well and so fast that it is worth the discomfort of poking it down their throats.

Confortis has to be given with food and my vet warned me up front that the first time you give it,my dog may vomit and if she does vomit within the first hour of taking it she would need to be retreated and they would replace the pill at no charge. I have 2 yorkies and the 4yr old is on comfortis and has been for about 2 years. The first time I gave it to her,she did vomit within the first hour and she had to be retreated the next day.She has never had an issue with comfortis since the first time. I live in florida and frontline just quit working for her. My 3yr old yorkie can't take comfortis because she is only 4lbs. and they have to weigh at least 5 lbs to take this pill. Zoe my 4lb has to be on Revolution because of her size and I have no flea issues with either one of them. I do not buy my pets meds at the vets office due to prices,I saw a lady at my vets office yesterday that got the same meds that I give my 2 yorkies and her bill was $235.00 and I ordered mine online and have them shipped from Australia for $114.00. The same drug companies make the meds, they are just cheaper in other countries than in the US. Your Vet will try to talk you out of ordering meds like this because that cuts into their profit of running their business.There are alot of online places to order, you just have to just start researching them. If anyone is interested try checking out CanadaVet.com ,their office is in Vancouver but the meds are shipped from Australia. They have saved me alot of money. Hope they can do the same for everyone else. BTW my 6 month comfortis was $56.97 and I got FREE shipping on my order. Good luck all.

It's a great product. Four long haired mini-dachshunds (we breed occasionally)and have been flea-free since we have stated using Comfortis. I divide the dose though - 1/2 pill with evening meal and then the other half the next day....our pups were throwing up so dividing the dose worked for us.

I used Comfortis last year, it worked great, I highly recommend it. I have 6 dogs, since they are confined to my yard, I only had to give each of them 1 pill. It killed all the fleas on the dogs and in the yard (when they jumped on the dog). The fleas haven't returned this year (so far) but if they do, I will go straight to the vet to get 6 tablets of Comfortis. It's great to not have to worry about fleas ever again!

This is the best thing in the market. My dog has never had fleas since the day he was born. This works amazing.
I don't know how new this is but he has been taking it for 2 years. Its worth the money. I live on a golf course where he can get fleas fast. If you want your dog to be flea free forever, Get the comfortis. Front line sucks and its not that great on fleas.

I felt I needed to post this. We started using Comfortis due to frontline not contolling the fleas in our area. I have an Australian shepard and a Schweenie. With the first dose within a hour or two my schweenie was lying on the couch and looked up at me with a funny look in her eyes. I called her over to me and she layed down but still kept looking a me. I could feel her heart pounding. It really scared me. I kept a close eye and after a couple of days of just lying around and acting depressed she was ok. She never vomited or Displayed any other of the many side common with his product. This happened for a couple of months of dosing. The next dosing however started off the same but she have very jumpy. Wouldnt be still. Moving from one position to another. The all of a sudden started scratching and rubbing her face on anythin she should find. After About 5-10 minutes she was still going at it. My first thouht was.. Is she havin a flea attack? But I knew none ofhe dogs had had any fleas since Comfortis was started. I picked her up and placed her in my lap and just happend to get her by both ears to stroke them and they were thick and swollen. Taking a closer look her face was also swelling. She has a thick furry face so I not have picked up on it. Her neck was also feeling thick and lumpy. I panicked and started looking for and after hours vet. By he time I got her to the car she was panting. They have her a steriod shot imediately but within 30 moreMinutes she was vomiting. She also got and injection for that. I will be giving her benedryl every 12 hrs unil all sympton subside. But thats all they could do. No antidote for reaction to this medication. Its been two days and she still is not drinking or voiding well. I have found many other posts that are similad to his where he pet has die immediately or a week or two later from liver and or heart damage. I hope this is not he case with my pet but I will not be givjng it again. To any of my dogs. By the way my Assie was also vomiting when I returned home at night. But being an outside pet it would be easy to miss small other reactions which have occurred in the past.

I'm also very afraid to give new meds, and especially anything taken internally. My vet quit carrying Frontline saying it was not working as well now, due to being used for several years now. (I get it at about half the U.S. cost at deadfleaz.com in Australia). I used Advantage once -- when my German Shepherds were a year old. One of them lay down and looked so sick, heart beating way too fast, etc. Luckily after an hour she recovered. I've used Comfortis for two months now, but I'm not sure I'll continue. I need something that kills ticks too. What's a pet owner to do????

It's the only thing that works for us.

I have purchased every type of flea control that is available and I have only found one that works and that is Comfortis. They say that it only works for one month but on my dogs it works 3 months. It doesn't work on ticks, of course but it does kill fleas, even fleas in the furniture.

I called my vet today and asked him about something to use for severe flea infestation and he told me he sold medicine for it. When my mom came home with comfortis I was very skeptical. After reading the insert I decided I would try it. Two hours later almost every flea she had is dead. While there are still a few alive they are in the process of dying. Hopefully this continues to kills the rest of them and she becomes happy and flea free again, because I hate seeing her miserable and scratching constently.

I AM AMAZED!!!!!!!!!!!!!!!!!!!!

I was so discouraged ... the day isnt over but I have tried EVERY freakin thing I could no a second of releif for him I felt so bad I couldnt get them off him.

Like it says started killing flees in less than an hour. I bathed him a couple hours later to maKE SURE IT WAS REAL ... LIGHT fur so its easy to see them when he was wet. Anyway I am so pleased with the results and if they keep dying even better....

I wouls also say as with any medication it could have different side affects asa has been mentioned abouve, but we all take medications that could affect us and them differently.

BUT FOR THE stuff you get at pet stores and walmart IT IS PURE CRAP and probably kills more animals than it helps

I give this a thumbs up....

After 9.5 years of Spike not having fleas, 6 months ago he got flea infestated because I procrastinated putting on his Advantage. The vet gave me confortis and it worked so I have been giving it to him for last 6 mos.
I feel that it has been affecting him negatively so I am going to discontinue it and go back to the topical solution.

After reading about occasional bad reactions to Comfortis, might I suggest starting the drug at one quarter the recommended dose and watching carefully to see what happens -if it kills the fleas and the dog is fine, maybe one quarter is enough for your dog. If not, slowly increase it. ALL dogs are different.

We have the same problem with many drugs for humans (eg antidepressants) - too often, doctors start patients on the "recommended dose", the patient experiences severe side-effects (eg nausea, vomitting, insomnia ..)and they give up, but they often do fine on a lower dose.

This was a life saver for my dog. He is a wolf/huskie hybrid with very thick hair. I washed him almost weekly with flea shampoo, sprayed my yard repeatedly and bombed and sprayed my house, nothing worked for fleas because of his extremely thick hair and undercoat. Even after shaving off as much as I could he still suffered from fleas. Until.....my vet recommended Comfortis. I am having problems getting him to keep it down, have resorted to peanut butter that seems to work, but NO MORE FLEAS!! He has been flea free for two months now, no more fleas found on him and I comb him everyday. No more scratching, chewing, and bloody bathwater. I usually don't try any products for a year, but in this case, it was truly a life saver. My home, yard, and best friend are now flea free!!

I know this product still has not been approved for cats yet. My vet has recommended this product as I have had a few flea infestations over the years. I have both cats and dogs. This medication works to remove the infestations and keep them flea-free. The cats and dogs use this medication near monthly. My vet stated "I do not see anything in this product that would harm the cats" and they have had no ill effects from this medication. Both cats and dogs must EAT BEFORE giving them this medication or they can vomit. I also treat my yard with a spray from Wal-mart that has seemed to reduce the fleas coming into the house from the dogs. I trust my vet and have seen no side-effects but pleasant ones NO FLEAS after a very short time. This has allowed me to be able to live in my home and not get eaten alive. Frontline, k9 Advantix, revolution have all not worked on my pets and Comfortis DID work very well.

Our vet prescribed our 13 year old chow chow AccuGuard. Okay. Two days after the initial administrative dose, our chow chow began to exhibit signs of lethargy and anorexia. #seemingly poisoned. Seven days after the initial administration of AccuGaurd, our chow chow had no sign of fleas, but she could hardly move from point A to point B. After 10 days, a visit to the vet, and $289.00 in monetary expense, for a full blood panel, a urinary analysis, and vetted advice, our chow chow appears to be hard-at-work to simply survive the effects of having become duly poisoned. She has NOT eaten much in the last several days. And FYI . . . I have done everything (in my powers) to get her interested in food, once again. And by "food" I am talking my having to cook up chicken, chicken livers, organic, grass-fed beef, calf livers, scrambled eggs, brown rice, etc. NOTHING!!! Now, I am just-a-wondering, was the idea of getting-rid-of-fleas worth the actuality of watching my precious chow chow becoming rendered useless, due to my having administered this poison? #experiencinggrandremorse

I'm so sorry. It's awful to watch your dog suffer when you were only trying to help. You must feel so bad! The product probably works fine for most dogs, but unfortunately not for yours. If your dog continues to eat nothing, please get in touch with the vet. You don't want her dehydrated.

When my pup won't eat, he will usually accept buttered toast chopped up like a treat, or cheese. Keep us posted on how this goes. I hope it's only a monthly medication and you are nearing the end of the 30 days.

You probably will need to start a plan B for flea treatment as you'll be unwilling to administer another product.

My dog has been on Comfortis for 6 years without side effects. I think I'll try the above suggested idea of giving half a pill and see how that works. It would save money and be less product for the dog's body.

By now Confortis has been on the market for years. Last year I couldn't find it, probably because the makers of Frontline, which KILLED my beautiful timber wolf after she was treated and chewed the neck of her grown puppy who also was treated, also make Nexguard. Seven days later at the emergency clinic, the vet said "seven days ago this animal had been poisoned". I had her autopsied, and the Frontline gang vehemently denied what now my regular vet says is what killed her. Confortus is Spinosad, and considerably safer...and is what the emergency room vet treated my poor timberwolf with when she came in...because the same Frontline that killed her, did NOTHING to kill the fleas!

Here's an article from the Natural Resources Defense Council which may be of interest, Non-Toxic Ways to Protect Your Pet:

Socks, thank you for the article. Very helpful. I wasn't aware of just soap and water being effective as first line of defense..and that flea/tick shampoos not necessarily advisable. But makes ALOT of sense! Looks like Dawn in specific is recommended to bathe for fleas.

I have used the medication that you put on your animals neck and it made sores on my cat. Monday 10/10/16 I took my Cat to the vet got his weight and they gave him Comfortis pill. This happened at 6:00 pm and at 1:30 am he passed away. My cat was old I have had him for 16 years but he was healthy. I went to bed at 11:00 pm and he was okay. No signs anything was wrong. Please do not give your animals this pill. I cant say for a fact that it was Comfortis but why take the chance. My cat was my inside pet my baby and losing him like this is horrible. Like I said I don't know for a fact but I wish I would have never took him to get it.

I'd forgotten I'd posted on this. I have experience with Capstar and Comfortis. I preferred Comfortis, but was told my local vets were no longer prescribing it due to side effects. The dawn, btw did not do the trick and I went to Capstar. It took several days, but eventually did knock out the fleas. I'd still prefer comfortis if I could get it.

In 2001 and seven days after using Frontline my female timberwolf died. Autopsy showed liver failure. Vet said something 7 days previously had poisoned her. She was always with me, and I can count. Company that makes Frontline denied any responsiblity, but admitted they did no testing with wolves. I will never use it again.

SaltiDawg no I didn't have a necropsy done but I wish I would have.

Tammy, you seem a bit uninformed. aggie-horticulture.tamu.edu/newsletters/hortupdate/.../Spinosad.html

Spinosad (pronounced spin OH sid) is a relatively new insect killer that quickly and safely controls a variety of caterpillar, beetle and thrips pests. Spinosad is derived from the fermentation juices of a lowly soil bacterium called Saccharopolyspora spinosa.

Relatively harmless, and acceptable for use in organic gardening.

You changed the post we responded to and have added all kinds of modifiers. You also have been disingenuous in your subsequent posts.

I will delete my posts regarding your incredible advice.

Don't concern yourself about my Bulldogs - they've all gone to the Rainbow Bridge, the last girl being 14 years old when she passed. Likely not many have had a (English) Bulldog that lived to be 14 years old.)

I can not think of a single drug that they received that was "okay for humans." No "human" food nor "human" drugs. Just drugs prescribed or approved by Vet based on Trials and experience and AAFCO approved foods.

We used it on 5 of our felines and my husband threw all of the cats off of the bed bc the fleas were dropping like hot cakes/flies. I had to take the bedding off, after plucking-up the dead/dying fleas and throwing them into the toilet, and placing new bedding on bed so husband could go to sleep. I then sprayed the entire place w/Vet

s+Best Nature's Health Care Flea + Tick HOME SPRAY for cats. It is a PLANT-BASED FORMULA Kills Fleas, Flea Larvae, Flea Eggs & TicksIt is Made w/Certified Natural Peppermint Oil and Eugenol Maybe, one should put pets out after administering Comfortis bc our 5 cats were running around/jumping, licking, grooming, and looking at the dead fleas falling off of them. Husband didn't even give me a goodnight-kiss like he always does bc he was sO upset w/fleas and cats. I used it on 4 one-year-young cats, 1 four-year young cat, and 1 eleven-month cat. I don't think I will use it on our 14 year-young, white/blue-eyed cat bc she has allergies to fleas/ticks/mosquitoes, etc. I am terrified that she may have a bad-experience/reaction. We gave our cats grounded-pills mixed w/a little h2o and sucked it up into a syringe-type injection-tool. Husband held cats while I shot it into their mouths one-by-one. ATM, they are going on 3 1/2 hours and I will probably keep watch of them all night long. Husband is in bedroom w/door closed and I had to get 3-4 cats out of room and off of bed bc they sleep w/me and not today after the falling fleas incident.

Our cats all have flea-collars on, 6 of them have reflective collars. The collars are 7-8 month long. 3 of our cats also had topical flea meds administered. The 14 year young cat has to use Vectra bc it is oil-based and it doesn't burn her fur off nor give her a rash like many others did. She couldn't use Serestro flea collare either bc it did the same thing. I tried NATURAL flea collars but they did nothing. Our 11 month young cat is medium-long haired and he still has fleas on his face. I will try the banana-peels in the yard bc we live in a pet-friendly complex and there are pets everywhere here in Long Beach, CA.
