We bought a cross breed puppy. He is now 10 months old and has numerous allergies including grass and certain foods. He is now on an expensive diet, can't walk on grass, our vet's bills are huge and not likely to get any less and he sheds heavily which aggravates DS's asthma. We love him but in hindsight we should have been more careful about where we bought him from. I have realised the breeder was a BYB, she hadn't had her dog (or the stud) health tested although she was a much loved family pet. Would it be awful to return him to her?
