The coyotes in the picture above were caught using grey hounds, which are sight dogs, which means the grey hound must see the coyote to pursue it, they will not chase or follow a coyote by using thier nose. The vehicle in the back ground has a "dog box" on it in which the grey hounds ride. The hounds have their heads out looking and the driver attempts to get close enough to the coyote and then release the dogs, and the chase is on. The grey hounds are sprinters, they do best on flat, open ground and do poorly in thickets, tall grass, fences, etc. They need to catch the coyote with-in about 1/4 mile, although they will sometimes stay with it and catch as far as a half mile+, at that point they will indeed kill the coyote, if left alone, BUT instead the driver trys to get to the catch quickly and kill the coyote and remove the hounds so that the pelt can be sold! If the grey hounds are released but do not have sight of the coyote, they will "miss" and run the wrong direction, at which time they will come back to the vehicle, and the coyote gets away!How do you use the dogs?? Do the dogs kill the coyote or do they corner them and you shoot them??
Like I said, we saw about 45 coyotes in a day and a half, I don't remember exactly, but I'd guess the grey hounds were released about 20-25 times! The dogs do get out run, the coyotes might go in a hole, or the coyote gets in thick cover, tall grass, thickets, what ever, and loose the grey hounds. Coyotes are quick, have great stamina, and thick fur which enables them to go through thick brush and fences quickly, where-as grey hounds run fast in a stragiht line with no brush, fences, ditches, etc. and don't follow thier nose to keep track of the coyote.
This form of "hunting" has been around a long, long time, even before "Randy A showed anyone how to call" /ubbthreads/images/graemlins/tongue.gif
