BBMI can't say if they planned to use the river water for the dog, or that the dog did use the river water. I do say he got water from somewhere, he couldn't have gone that far without it. Of the two possibilities that I can think of, the river or the camelbak, my best guess is the river. A hot, thirsty dog, most likely loose beside a river... it's obvious. If not the river, then the camelbak, unless someone can think of more sources of water. They WERE woefully negligent, I'm sad to say, not just with their dog.
Agree...but I don't think it was planned. Sadly, If the dog drank all the way to SL, it could have been the LAST to perish, since I don't think the family would drink that water. Then again it all moot in the end.
