Blood Dog Trainer?

[Lil Silver]

I used to work mine with deer tails in the yard. I'd put him in the shop where he couldn't see, tie a string to the tail and drag it through the yard without him knowing. Do some zigs and zags through the grass. Tie it in a tree at a stopping point. The better he gets, make the course a lil harder. That lil dog was a man. It got a lil old getting calls after dark to bring Tiger to find a deer.
