Cooperhaus K9 was established in 1971 by Calvin Cooper, a well-respected dog breeder, and trainer. He bred and raised Doberman Pinschers in the '50s but began focusing on breeding quality German Shepherds beinginng in the '60s, after acquiring a dog sired by the renowned 'Bodo Von Lierberg'. Cal Started breeding Rottweilers in the '70s. Cal's honesty and reputation are beyond reproach. Cooperhaus has grown quite a bit since its inception but we owe our gratitude to Calvin.
