We are going to enclose our deck so Angie can join us when we are chillin' outside. I want to get an outdoor bed for her and was looking at a dog cot similar to the ones seen at shelters. It seems like a good idea; above any dirt and bugs, easy to clean, and comfy with an old blanket on top. Do these last? Do they feel comfy in them or would I be better off with a regular dog bed built for outdoor use?
