Apoquel predisposes a dog to cancer by affecting the immune system. Risks from Apoquel include immunosuppression: allowing skin infections, severe infections (e.g., pneumonia), or infections with parasites like Demodex to worsen. It may increase the risk of developing tumors.
That tumor was a turning point for her Mom and Jem was taken right off Apoquel.
She asked if I could do anything for the tumor other than surgery and sent me a picture. I replied, "Easy Peasy!" I told her that I didn't even have to see Jem, it could be a phone consult.
