I've seen how this works. The first greyhound will run the coyote into
a circle, while the second one rests. Then the second hound will take
over, while the first one rests. It becomes a relay race for the
hounds, while the coyote has to run twice as far, and so he will
eventually grow tired, and be taken down.
