Carl H. Altenbernd, owner of Gun Dog House Door® Company and Gun Dog Kennels has accumulated over 25 years experience training retrievers in west central Minnesota. He personally owns four black labs that make their home in a twenty-four run dog kennel.
Carl designed the Gun Dog House Door® through the frustration of watching the hard driving, alligator-chewing Labs eat every “brand name” dog door on the market. He persisted in designing a dog door that meets all of his expectations and more. His dog doors are Black Lab and Minnesota weather tested, now that’s tough!
