http://www.easttexashogdoggers.com/forum/index.php?topic=34855.0Read this threAd there are some excerpts from the book. Most of our dogs go back to what the old timers say was the best black Perry bitch ever. She was named Dixie. They bred her to a Woodruff ranch male dog, from that CB was made and he was bred to a bitch out of New waverly. This is where Erik's dogs started and mine have been bred from his. Ours really aren't true perry dogs but they have some of the right kind of old blood in them. Good luck with your search.
