Another picture of Sydney's dog house, now 4 inches higher. The platform is made of 2x4's salvaged from the shed we recently knocked down, the top is 1/2 inch plywood I've salvaged from random job sites around town over time. The outside board, the only piece of wood I had to purchase is a 1x6 pine for the house to rest in, to prevent the house from slipping off the platform, but also to give the outside a finished look. She has a much easier time getting in and our now.
