If you don't have a dog, get one. If you can't get one, borrow one. Next time you shoot a deer, and you're able to find it. Leave it there and go get your dog. Take him to where you shot the deer and teach him to use his nose. Any healthy dog can track, you don't need a blood hound. I have an Australian Cattle Dog (Buddy) and he is great at finding dead deer. I'm even thinking of using him to track live deer this year during firearms season. If your dog is having trouble understanding what you want him/her to do, try rubbing a glove over the glands of the deer and then put it in a zip lock bag before you get your dog. Let him smell the glove and slowly lead him to the deer. Praise him for finding it- vigorously! I love my dog very much, and this is now one of my favorite parts of the hunt. I even reward them with a small piece of meat from the animal, but too much makes my dog sick.
Good luck!
