Amber was extremely knowledgeable about the breed and committed to finding good homes for her puppies. We were kept apprised of the litter status and the emerging disposition of all the puppies. And of course cute videos to help us find the one! Communication was great and her passion and love for animals really comes through. Our puppy is wonderful, healthy and a great addition to our family.
Health testing is one key piece of responsible breeding and is performed on breeding dogs to prevent the presence of heritable conditions in their puppies.
