When I was considering buying a new dog house I started to hear of the insulation of the dog house. I admit that I had never thought of it. I guess I always just assumed that the hair a dog had was enough insulation and I didn’t have to worry about an Insulated Dog House. I guess I mostly only thought of providing shade in the summer and cover in rainy weather. I now know that dogs are very susceptible to the temperature. I ended up getting a Structural foam designed Igloo Dog House. The reason is the design provides for both insulation for the temperature and ventilation for air flow.
