I dont see British quarry being a problem or running against any BullX. We have them here and in general speaking terms they dont make better coyote dogs than straight Staghounds.Dont get me wrong the American Staghound is not some superdog , just one bred for a very long time by men smarter than me, I think you have to look at Quarry. The coyote,, is something special, master of the running fight and I'd put my money on a good winter 30 lb coyote against any two lurcher dogs.If dont have it, you cant hunt it , then you cant breed for it,
