I have an Aluminum dog box for sale this is a factory built box made of insulated aircraft aluminum. The deminsions are 20in. tall x 20in. deep x 30in. wide. I had a medium sized pointer who passed away and he was very comfortable inside. It would work well for 2 or 3 small dogs like beagles or fiests or 1 50 to 60 lb. dog. The price is $285.00 shipped to anywhere in the lower 48. I will e-mail pics to those interested.
