Does anybody have any experience with this injection? We have struggled with our 8 yr old GSD scratching all the time. We had him tested, and he is allergic to many many things, including dust mites and Bermuda grass, which is hard to control. He has been on limited ingredient dog food and monthly allergy shots for years, which help some but not great. Then we tried the cytopoint injection last year, and he is a new dog. No scratching at all, very relaxed sleeping, he seems like he feels SO much better. The shot is not cheap, about $120, and it lasts about 3 months before he starts scratching again and needs another injection. He no longer gets the monthly allergy shots, and we are very pleased with the results from the cytopoint injections. I'm curious if anybody else has tried this treatment? Thanks for your responses.
