RE: Tracking dogs. whats the best?
ANY dog willfind a dead deer for you.
But it has been to my experience that a dog that has equal vision and hearing just simply find them quicker.
Dogs with "pure smell" traits work better at night.
Just take care of what ever dog you get and dont just leave him chained or penned in the backyard. Before you do that go buy a good tracking book and study it afield. MHO
Hope I helped. Enjoy your friend and treat him as such.
