*The OFA/PennHIP Diamond Rating assigned to adult dogs on Mountain Dog Companion is intended solely as a general evaluation. The dog's vet, overall health, and past puppy feedback are also consulted ensuring good breeding practices. Having the OFA/PennHIP diamond does not guarantee or imply any specific outcome, trait, or characteristic in any puppy produced by the parent dog. Individual puppy development after leaving our care is influenced by a variety of environmental factors beyond our control.
