The two founders, Howard Atkison and Bob Guinn, have over 60 years of manufacturing experience. They have had more than four generations of large outside dogs in their immediate families. For years they have searched for a manufactured dog house with real insulation and a door that could not be destroyed. This combination of events has led to the creation of the Dog Palace and DP Hunter insulated dog houses. These are the first manufactured insulated dog house with real foam (Styro/EPS) insulation and an indestructible, self-closing, insulated door.
