Those aren't greyhounds, they are American Stag or Lurchers. Great dogs. Very smart, also foxhounds are great for tracking yotes, but you need open fields for the stags. Too thick and dense down here.
There are dog men all over South Georgia who have the hounds to run and catch and kill coyotes, and to them nothing is exceptional about it. I know men who run fox and coyotes, some Bobcats, and I know men who only run yotes and nothing else. Rvick: I'm not sure if you don't have the hounds to do it or if you're not letting them finish the race, but there are Walkers all over SGa from fox lines that catch and kill coyotes on a regular.
