Good afternoon all, Our puppy is 11 months old. He is a rottweiler. We took him to the vet yesterday had some xrays and found that he has hip dysplasia and both his knees have cruciate ligament ruptures! We are now embarking on the long process of surgeries and therapy which I am aware wont heal him 100% but we are committed to do everything necessary to help him. The vet has advised us that these issues are a hereditary disorder and it is likely the other puppies in the litter have the same problems. We bought the puppy from a family with 2 rotties. I visited their home twice to see the pups with mum there was nothing untoward. It seemed like a legitimate family just having a litter with their pets. I met mum and dad, I was told both were pedigree and the contract of sale included a clause stating they had been health tested and hip scored and were perfectly healthy.. My question is other than focusing on our puppy and making him better are there any other steps I can take against this breeder should I have missed something and was duped?
