Extremely HelpfulFirst, I'd like to thank you for the Natural Dog Training DVDs. They are extremely helpful! I especially like the detail on the pushing exercise because I'd tried pushing before with my dog, and he'd balked - I hadn't understood all of the mechanics until I saw you perform the exercise. I'm sure I'll be able to help Tyler push now. :) I've been trying to work with him in many ways, and this is by far the most helpful. My current goal is to get him to pass the AKC Canine Good Citizen test (just because). We're also going to be starting agility classes (again) soon. No other training method has been as effective as this one, and I look forward to training sessions now (Tyler does, too!).
