Bought this inexpensive dog house because I wasn't surey dog would even go in it. Luckily she is in it all the time. The fog house is under a patio and she still prefers to be in the house even when it's 100 degrees. She's a mixed breed that weighs 75 lbs. I put a huge bed in the house because she pulled the smaller beds out. Maybe a really tall dog would be too big but definitely big enough for the majority of dogs.
