I had a large male doggy that I found as a stray and he never would house train thus he became an outside doggy. He would never use his igloo doghouse se we got him a large square shaped dog house, he still wouldn't use it. He would sit outside in thunder storm and get rained on, my poor boy
so we took plywood and made a shelter instead it was big and had a back, sides, top, bed no front. He was nervous to go into anything box like, but since the shelter had no front and was big (tall and longenough that 4 of him could have fit in there) he felt confortable. It kept rain out and block wind pretty well. It was the best we could do since he wouldn't use a dog house. We added saddle blankets and a carpet to the floor of the shelter. It worked out for him. When we moved homes, we then had a nice large covered patio. So we then put a couch on the patio along with an electric blanket during winter, he loved that. All he needed then would have been a tv
he lived to be 12 years old. I had to get him put top sleep last October
but he was an amazing big boy!
