Our puppy was diagnosed with severe genetic hip dysplasia at only 7 months old. He can no longer put any weight on his rear leg and after seeking a second, ortho surgeons diagnosis, we were again told the only recourse was a full hip replacement surgery and that eventually his other hip would also need to be replaced. The quote for the surgery on one side was $8,000. We paid $2500 for a supposedly healthy puppy from a supposedly responsible breeder. After finally getting a response, Mr. Cantu at Rivercity Rottweilers would not take our puppy back per the contract, stating his current dogs were sick and he had no room. He also suggested we have to make the decision to put the puppy down. We have now had to threaten him with legal action in small claims court. DO NOT purchase a puppy from him! Even with the hip and elbow guarantee, they mean nothing if he is not willing to honor the contract in the supposedly rare cases in which they happen. He is NOT a RESPECTABLE or REPUTABLE breeder. There are plenty of other breeders you can choose from for the same price. User's recommendation: Stay away. Go somewhere else.
