Pet's info: Dog | Collie | Male | unneutered | 3 years and 5 months old | 70 lbs
My late collie had allergies upon arrival(never did before) became atopy dermatitis which was treated and resolved. She then had IBD and Addison's then died of liver cancer. I got a new collie from same breeder(4 yr male) who is very healthy, but began sneezing and scratching and biting himself on 2nd day like previous collie. Both were always in outdoor kennel and never in a home. Could this be from no exposure to certain allergens? I'm afraid to try another. Home is immaculate. Suggestions?
