I work at a rescue shelter, and as you can imagine some of the dogs there were never taught that you shouldn't use a human as a chew toy. There is one dog in particular, named Mori, I believe he is a cur/hound mix or maybe feist/hound mix, and he almost gets himself into a frenzy, and mouths so hard it hurts, a lot. We have a fenced in area around each line of the runs, and each dog gets out into this area at least once a day for 20+ minutes at a time. I have successfully taught Mori not to mouth me when I let him out, as I would grab him and throw him back into his run, and then let him out a few minutes later (rinse, repeat), and he learned that mouthing = end to out time. My problem is when I walk back into the fence to put him back after his time is over. Mori gets excited and goes into that mouthing/jumping frenzy. I still have some marks on my arm from yesterday (I did not work today, day off). Throwing him in his run isn't going to work for that, he knows that he's getting put back anyway! Does anyone have any tips for working with a dog like that? Other staff members have used the "kneeing in the chest" method (that I don't like and don't use), which has only created a dog who mouths and jumps on your back/sides so that he cannot be kneed! He's a smart dog, lol. Help? opcorn: Oh, and this is him, to put a face to the crazy creature. He's really very sweet when he isn't biting the crap out of you.
