How far can coon hound smell?

A coonhound's sense of smell is often described as being "a mile wide and an inch deep." This means that they can pick up on scents that are very faint, but they may not be able to track a scent for a long distance. The actual distance that a coonhound can smell varies depending on the individual dog, the conditions, and the scent. In general, coonhounds can smell scents that are up to 10 miles away, but they are most effective at tracking scents that are within a few hundred yards.
