Homemade Venison Dog Biscuits

Every year hubby (O Wise One) kills me atleast one deer and butchers it. We are not talking the big monster bucks with the antlers the size of some small states but rather a small doe or young button buck. As O Wise One says "ya got ta boil them horns a long time to get them soft enough to eat". After he skins and cuts up all the choicest pieces for the freezer there is always those small trimmings and pieces left over. We used to throw these away but have recently found an excellent use for them. We grind up those pieces we don't want for ourselves and freeze them for making venison dog biscuits. Well both puppies will roll over in a minute for 1 so I'd say they are a hit.  Just another way to use something we would normally throw away.
