Pancreatitis is a very serious condition and I hope your vet is going to try to see your dog ASAP.

Has she had her teeth thoroughly checked and is the gingivitis being treated? I would be concerned as to what is causing her nausea. Were you aware that drooling can be a side effect of Cerenia?

Ask your vet for a less expensive medicine for the nausea, but I'd be trying to find out why she's nauseated. The symptoms you described are not a good sign.

She is not on the cerenia,she has only taken it occasionally.The gingivitis was diagnosed in 07 and the drooling started at that time to.She has been on medications off and on since then.Antibiotics mostly.She went in for a teeth cleaning a few months ago but it was not done at that time.She was very distraught about being left I guess and they suggested waiting.

With her mouth problems I'm surprised a vet would suggest waiting on teeth cleaning & a thorough mouth exam (under anesthesia).
IMO, she's had this problem too long and it sounds as tho they're treating the symptoms and not trying to find the cause.
Maybe it's time to seek a second opinion...........

One of the first things that comes to mind is slippery elm bark- should be available at any health food store. Some people swear by this stuff for stomach/intestinal problems, and some people think it is worthless. I've had good luck with it in my cat when she is feeling sick, and I have taken it on occasion with mixed results- sometimes it helps an other times doesn't seem to have much effect.

I did a quick google search for slippery elm and pancreatitius and was surprised to readily find several sites about dogs and the use of slippery elm bark with this condition. If you have some time, it might be something to further research.

Best of luck.
