Why won’t my dog go in his (expensive) dog house?
A dog could have an aversion to going inside a dog house due to a learned behavior or for no apparent reason at all. If he prefers a certain area of the yard, try moving the dog house to that area. Next, try placing his water and food bowl in the dog house to further encourage him to go into the house. You can also try positive association by giving him a treat every time he goes into or near the house. Finally, the house might not be big enough for his size. Hope this helps!
