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.

Gun Dog House Door "Big Dog" Pet Door was developed after the initial success of the regular, heavy duty Gun Dog House Door. The design is the same but very much larger with a flap dimension of 15" x 23". Gun Dog House Door Company specifies dogs to 200 lbs. and up. As always, we recommend that you measure the size opening your dog actually needs rather than go by weight. We do not recommend this door for very small dogs or cats.
