Could Frontline have made my puppy sick?
I have an 18 week old Lhasapoo. She is 2.5 lbs and seemed very healthy when I got her from a coworker.
I purchased Frontline Advantage for puppies 7 weeks and older, and under 10 lbs. I followed the directions and applied it Thursday afternoon.
Friday when I left for work, she seemed to have dry heaves, but otherwise was fine. When my son came home, he said she had vomited several times and was lethargic (my word). She perked up when he took her outside. She seemed a little quiet the rest of the night but otherwise okay.
Saturday she vomited constantly and didn't eat anything. She was extremely lethargic and if she did walk, she seemed to stumble, almost like she was drunk. I brought her to an emergency vet Saturday night and they admitted her to put an IV in. They kept her until mid-day on Sunday and she came home much better, happy to see us, acting a little quieter, but otherwise almost her normal self. We were told to continue with the antibiotic they gave us and feed her just baby food and sugar-water. She held that down but this morning began vomitting again. Again, she's lethargic.
I'm really worried because she's so tiny to begin with. If she's not better when I get home tonight, I'll take her back in, but in the meantime, any suggestions?
