Amazing how much we as trainers can learn from each dog!
Interesting comment about "force" and esp. with Dumbbell. we had a couple of different trainers involved when we trained Baron with the DB. one was PO approach and one used a small level to get him to "Take it" in the beginning. A third, nationally known trainer in a seminar I attended use a variation of the oft used "Ear Pinch" that worked very well with demo dogs in seminar - shye used an "Ear rub" no pinch or real force - just rubbed ear with finger and thumb till dog opened their mouth, popped DB in and out quick and HUGE praise - worked very well! I wouldn't call it really force - just "irritating the dog to open his mouth to get DB in in the beginning to give him the idea.
I think it is great that "Mutts" can now officially compete - Great Idea, AKC!
