In a running dog these are the qualities I think are needed

In a running dog these are the qualities I think are needed. First, endurance, because no dog can make a race after a red fox without it. Then speed, a good nose, lots of ambition, good sense and the more of that the better; and will need to be able to hear well to enable him to cut corners if he happens to get behind, as any dog is liable to do.
