With ingenious minds like that of saltysack and his vest = JRT sleeping bag idea, I was wondering about a bivy sack/bag for my dog. After doing a brief search I couldn't find anything like what I'm envisioning. Either a completely separate Labrador Retriever sized bivy sack with all the benefits that come with a bivy... OR ...a modified bivy sack for the handler that has an attached compartment for his/her dog.
Why not just use a 2 person bivy? Because my dog isn't the size of a human being and because I would like to keep him from sharing any unwanted water from soaking into my sleeping bag. You can only towel a dog dry so much.
My guess is that I'm going to have to make this myself.
Worth looking into?
