Black Rock Canines is a professional dog training service provided by a veteran-owned small business enterprise. This is not all. They offer military dogs for sale to the army. Black Rock Canines was established in 2017 by David Rivera, an Air Force veteran having served as a K9 officer in New Canaan, Connecticut. His learnings taught him that genetically-tested healthy U.S.A.-bred dogs have become rare in the marketplace these days.
