Hemi is turning out to be pretty good at tracking horses up on our mountain in the thick woods. They spread out in the heavy brush. Not quite sure how an animal that big can be hard to see in the woods but they are. They stay up in the heavy brush I just leave them. No way to push four of them out. They are cagey! I wait till they drop back down into one of our pastures then gather em up. They are regular escapees and know the drill!
