we hunt them w/ greyhounds here in nebraska, it is a blast!! To answer your questio you need 1 hell of a big dog and a good at that. I've never seen 1 dog hold a coyote and kill it. We have to use 4 or 5.! I have seen 2 big good 3 year old males catch and kill a coyote but they would only work best w/ just them 2. If you can afford to come out here I know sum guys selling out.(402)843-8353.
