Now that's an interesting thought. I've never heard of such a thing, but it is interesting. A suggestion though, if you want to try a realistic bite, get yourself a length of canvas covered fire hose, oh about 15 inches long. Slit it lengthwise. Use it to cover the arm. Wrap about 4 layers of heavy cotton cloth on top. Use that to catch the dog. Back before the days of all the assorted sleeves etc, and you choice of equipment was burlap or bare skin, it's what we used to use. It gives the dog a very realistic feeling. When the dog was biting, the decoy would roll his arm inside the sleeve and the dog could feel the muscle moving. It really helped build a strong bite. One caution however, you will get some nasty pressure bruises and bumps. Thank God for modern equipment.
