There is a kennel in Wyoming that has sold pups that are being used all over the country. I'll see if I can come up with the info for you. Also, there is a fellow in Tennessee who features bloodlines from the Wyoming kennel. If you are looking for treeing dogs with plenty of grit, you might consider Ladner Yellow Blackmouth curs out of Mississippi. They just naturally make good dogs for coons and bobcats, and I believe Curt Ladner has records of people who use them for lion.
