Does anyone have any experience with Vet prescribed Cytopoint on their dog due to Atopic Dermatitis (environmental allergies, causing itching, scratching, chewing, hair loss, hives, etc...) and if so how did your dog react to this injection? My Toby had a Cytopoint injection last Thursday and is having a fairly bad reaction to it and is not doing well, (lethargy, anorexia, bloody diarrhea...) he's pretty sick. I am just wondering if anyone else has ever had experience with this stuff. Thanks!
