My Dad has a wiener dog named Milo. He has been on many class III runs, and he survived a raft flip in the spring with his life jacket on. He's older now, so he doesn't do much barking, and we have to watch his body temp. He once jumped off the the bow of the raft on the north Santiam after a flock of ducks, without his life jacket. The little bastard sunk like a rock, but I managed to grab him. He was a pain in the ass when he was a pup, but he is pretty fun now. We took him on the Upper Clackamas a week ago and he did great.
Wishing I was on the river instead of surfing the web...
