My son and I built a dog house with 2 pallets, and plywood. All materials donated. Then someone on Craigslist donated roof tiles and vinyl flooring. A friend was able to cover 2 walls and the roof. Still have to lay the flooring.
Dog house, with porch, terrace, three windows and closing doors for inclusion when needed. Including a division/separation for different dogs; two small dogs live on one side and one big dog on the other. Bottom right photo shows entrance for both you and
