For the first Doberman he needed concentrated bite work and routines on it to be effective with a good bite and when to do what he needed to do. The second one had very little control from handler once off leash. Third one had a good hit, good out to the most part and control besides a few moments of wanting to hit without command. Fourth one, love the representation of the natural look, was nearly the best with the best control, the hit was well placed, out was well was good, but the grip was a bit loose and the dog did not bay the target in place. The fourth one and the third one are tied, but the third seems more affective though he will leave a few more holes in the perps hand for taking that shovel.
