http://www.dogproblems.com/sl.cfm This is Shorty. He's a Rat Terrier we just rescued from our local Animal Shelter. We'll be using Shorty as our new demo dog, for the next several videos, as he has had absolutely NO PRIOR TRAINING. With my system of dog training, we like to start with crate training, so we can keep the dog safe and to prevent him from developing bad habits, when we can't supervise him.
