I have mentioned before that my dog suffers from hip dysplasia. We were looking for something that would help him. He loves to sleep on the floor and we have had to stop him from doing that. So, we found a simple solution. We have 3 kids. No more babies. But we still have an older baby mattress. He had been laying on the blanket that you see as his bed. We just put the baby bed on the floor and covered it with his blanket.
My reasoning behind this is that the bed cushions his joints and gives. The floor he loves to conk out on does not give. Hope this cheap tip helps someone. Leave me a comment if it does and let me know you stopped by!
