When to turn the Catch Dog loose?

It depends on the country I'm huntin. Sometime's I'll walk my CD in as far as I can to be sure the bay dont break and then have my CD trying to keep up with a runnin hog and the bay dogs. But I've cut him loose at 300 yds away. One of the draw backs to lettin go so far away is the CD is gonna be (or had better be) haulin azz to that bay to catch and when he gets there he's not going to be as fresh as he would if you let him go from 20-50 yds away. So I try to get there to them as fast as I can. The bay dogs are normally caught with the CD and they have all done there job so there waitin on you to hold up your end of the deal.
