Hey, i've got a stag grey hound and she's tiny, so she turns on a twenty cent coin, and quick off the mark but doesnt have huge top end, my other mate has stag hounds and none of them can keep with a hair over a long distance, and the hairs turn them inside out, but they all get foxes no worrys, from what i,ve heard a deer hound or irish wolf hound would not the adgile enough for hairs and foxes. cheers mike
