Our family have recently bought a puppy from a local breader. The puppy 12 weeks old and came with papers and was flead, wormed and vet checked. We have had her for over a week now and have had a vet check of our own. The vet told us that the puppy has a hernia that may cause problems for breeding and also she has a luxating knee. I just feel that the breeder has failed to inform us of these issues and it may cause problems in the pups future. Should I contact the breeder , i feel as though i have been ripped off also :/
