I am looking for some help/advice. I have an 8 year old labxcollie who I've had since he was 6 months old. In August 2015 I moved into a new house and in October 2015 he started itching his stomach terribly. I took him to the vet who gave him a course of steroids that stopped the itch. In June 2016 he started scratching again and chewing his legs. I tried everything including dog coats which made little difference. It seemed to improve over the winter. This March he started again so I took him to the vet who put him on apoquel and took bloods. They have come back saying he's allergic to 4 things - dust mite d.farinae, storage mite T.putrescentia, storage mite acarus and penicillium notatum. The vet has given me more apoquel and says he can stay on that forever although I'm not sure given what I have read about this drug. They have also offered immunotherapy. Does anyone has experience of immunotherapy and whether it works? The vet says it works on 70% of dogs. I have never had an issue since moving into this house so my final option is to sell up and move! Any help/advice greatly received. Thank you.
