Atopic Dermatitis and recurring skin infections--antibiotic not working anymore

I know this post is a couple weeks old but I wanted to let you know my dog has been on apoquel twice and the first time it worked well for him but the second time it was not as effective which is common. Long-term use is somewhat advised against, of course there are conflicting opinions on this.

My dog, also 9, has recently developed a bad allergy to something starting in June and has only gotten worse in January. After seeing the specialist we are in the middle of figuring out if his allergies are food related or environmental (dust, mold at this point since he's still itching horribly in the dead of winter with snow on the ground). They injected him with cytopoint yesterday and my boy already can FINALLY sleep over 15 minutes without itching. In fact his itching has almost completely stopped already. If this does turn out to be an environmental allergy, we will be doing the shots every month over apoquel. There's scary stories out there surrounding apoquel. Maybe they're something to take into account, maybe not. But I say the cytopoint seems to be better, at least for dog. Good luck!
