On a little different note, my son-in-law deer hunts and bagged two yesterday. He said his outdoor dog (a lab mix, I believe) loves the deer shins. He brought 4 or 5 over and I put them in the freezer. It's just the leg of the deer, appearing to be from about the knee on down, including the hide and hooves. There's no doubt in my mind that Bentley would go crazy over these and he could only have them outside in his pen, which is quite large, almost as big a many city lawns.
Any thoughts on this? It sounds similar to the antler treat. By the way, my son-in-law said there's very little flesh involved.
