I think this is a hard situation to be in. In no way would I blame the breeder, however, it's not fair to blame the owner either. Sometimes we don't make the most educated decisions when buying a puppy and we make emotional choices. I learned the hard way when I bought a mastiff from a less than reputable breeder. He had tons of health issues and I did not have health insurance. However, when I decided to be a pet parent again I spent months researching breeders and purchased health insurance from Healthy Paws. I'm not saying I bought the perfect puppy, but I tried to increase my chances of having a healthy pet. I really feel for this owner, but it's not the breeders fault either. Genetics can be a tricky thing and breeders can't guarantee a perfect dog.
