R2L, you're talking about walking a dog? That's not work. That's just walk.

Put your dog on a mill or whatever else you have, and make him run as hard as he can for 60 minutes. Your dog will drink water. I don't condition dogs for a show by walking them so I don't know how that works.

High intensity mill work or jenny, and your dog is going to drink water I don't care how much raw feed it gets.
