>>2371091I've been on one camping trip with a dog that had a pack on. The two sides weren't packed the same so it kept pulling the dog in one direction, it was kind of funny. You'll definitely want to make sure they're well balanced.
Both that dog and my dog love water too much, and there's too much of it around here. I can't really think of too many things I would pack in there that I wouldn't mind getting soaked once the dog inevitably finds water.
