I take 2 35-40lb dogs with me when I camp. I've been trying to think of a shelter I can make for them that would help keep them warm and dry. I thought about making a Tyvek dog bivy but they really really don't like the crackly sound Tyvek makes.

One solution I thought of was to make something like an umbrella shape with an entrance I can lay over their dog beds to form a low dome or flat cylinder made from Reflectix. I figured I'd put loops around the perimeter to stake it down.

Has anyone tried any kind of dog camping shelters? Any ideas?
