Do you usually track the animal yourself???[:-] Isn't that much to hard?
Your dog is *made* for this, even a lab!
My dachshound (11months) goes 24 hours old, 1000 yards long tracks which I made with about 250ml (a glass full) of blood. No problem for her, as long as there are no fresh tracks, which she likes better [&:]
Good luck training your dog... Tracking with the dog is a very rewarding work for both of you and it will help you find deer you would never have found alone!
