Yeah, gotta agree, making the dog carry gear is bogus, unless the dog drove to the store and picked it out himself.
Now, food and water? My guiding principle is every camper's gotta carry their own weight.
Still, Barney always gets a decent cut from my rations. He's a very active dog and I have trouble maintaining his weight on longer trips. Section hikes are no problem. Somewhere around two weeks I start having to crank up his calories something fierce or he starts loosing way too much weight.
BTW, I appreciate the posts of various dogs in their packs. The Chuckwagon's OK but I can't help feeling there's a better pack out there for my little monster.
