The dog will not care if it is the trimmings or the jerky, And the only way I would give the dog venison that I myself could eat, would be as a training tool, and a thank you for helping me track a dead or wounded deer. We have 4 dogs, and we foster. Even a mouthfull each is a meal for the family. NO, flat out , no. If the dog earns a reward for helping to recover a deer, then a unique treat would be appropriate, and a beef bone will thrill him to no end. Beef bone are unlimited, and the venison is not. The most I will give the dogs, is what would otherwise go to waste, or basted biskets. You do as you will.
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
