All vom Mountain Creek puppies are guaranteed to be clear of von Willebrand's and Hemophilia. Our puppies are also guaranteed to be HD free for a period of 12 months. To honor this guarantee, we must be notified immediately by you and your vet once the problem has been discovered. If the problem is one that may improve and be corrected over time, the guarantee can be extended if agreed by both parties. Should you decide to return the dog, it will be returned at the buyer’s expense. Returned dogs will be replaced with one from the next litter. This guarantee applies only to the original buyer and is null and void if the dog was purchased under false pretenses, abused, or bred prior to being certified for breeding per VDD regulations.
