Dog owner nc
I two have been down the apoquel train. Luckily my dog did not have cancer as a side effect however she did get diarrhea, ear infections and vomited. After doing research I didn't like the apoquel and took her to a certified dog dermatologist. All vets said it was food allergies but the dermatologist did a test and found out she is allergic to human skin cells, every grass and pollen imaginable. The dermatologist put her on immunotherapy which take two three months to start working. That was 7 years ago now and I have an old dog now that is still loving life. Go see a certified dermatologist for dogs to stop the itch and scratch.
