Songdog, you beat me to it. I don't own any dogs, but hunt with some friends that are hardcore serious. They get coyotes I'll never call, and I get coyotes they'll never run. Our coyote population around hear is very heavy, with no sign of dwindeling. I belive what Q Wagoner wrote in that if you want good calling, give them a break from spring till fall.
Jlingle, I can hook you up with a friend that would be glad to take you. LTFB
