Pets

After about a month on Apoquel, our dog started eating less and less and then would eat hardly anything, even treats, without extreme coaxing from us. She also became sluggish and lethargic with diarrhea and some throwing up. The vet took tests but couldn't figure out the loss of appetite. I then checked online for side effects from Apoquel and was upset to see it fit many of her symptoms. We stopped the Apoquel and within a day or so she was back to her old self, including her appetite.
It's possible it was all a coincidence, because she also had a urinary tract infection and had been on antibiotics. There's just no way to know for sure, but we plan to stay away from Apoquel in the future.
