My dog carries only his own stuff, not mine. In fact, I carry his sleeping pad and his first-aid stuff as well as the shelter for the two of us.

Insignificant weight and cost involved in the measures I suggested to keep the canister fuel flowing:

Windscreen big enough to go 7/8 of the way around 2 liter pot, double layer of heavy-duty aluminum foil: 0.5 oz.

Piece of old blue (closed cell foam) pad cut to size of MSR large canister: 0.1 oz.

Armpits: Already there, I hope!
