That all becomes a "handle" issue. I leave the woods with my dogs, when I am ready, not when they are ready. Oh, and yes, I do hunt hounds.

Plenty of references for those who doubt you can teach a hound to come back in when called. I have literally called them off a track when they were only 20 yards behind a hog, because of one reason or another. Wether they can see the hog or not, when I say it is time to load up, we're all loading up including the hounds. I don't settle for less. Set standards and live by them. You'll enjoy life more. I promise.
I personally dont like the thought of making my dogs quit a hog, they might make a habit of it. As for the handle, if my dogs didnt handle well they wouldnt be here.
