So I found a guy near us that has a good pack of tracking dogs for fox and coyotes that tend to run them in a loop of about a 1/2 mile. the old guy always used a double barrel 10ga but he said his eyes are not as good as they use to be and he was looking for a catch dog that could be let loss as one goes by. My frist thought was one of the sight hound breeds. But my question is a lot of the land we hunt is heavy cover with opens anywhere between a few feet to a 100 yards or so so would you all think any of them could over take one when it goes by and before it losses them in cover
