My English Setter understands find the bird. This year, Minnesota said we can put 'em on a leash and track deer. I told her "find the deer" twice and we went to the deer without any detours both times. Both deer bled a lot and it would have been hard to lose them. If I took away his shoes, Stevie Wonder could have found the first one, it only went 30 some yards. The second one had a almost a continuous stream of blood, but went 300 yards+. Very simple trails with all the blood I could ask for. Ideal training trails.
