Aha Moment! My trainers methods worked!
So Ruby and I have been working on passing the CGC. Our biggest hurdle has been the 'meet & greet' with other dogs. We are fine in class with 8 - 17 other dogs (go figure) but once we are on the road or sidewalk all bets are off.... until this week.
Method: My trainer had me walk with Ruby in a heel position, always in a heel position. "Nope" then check with prong if she broke the heel. Last class she stayed in heel without any corrections. We stopped using prong day after last class. After 4 days of walking with her in heel, martingale collar, leash loose 'J,' end hanging over neck, she stays in heel. All I have to say is 'nope' if she is even thinking about breaking the heel. She corrects herself.
This morning this method was tested. A hyper small dog at the end of its retractable leash and barking passed us in other direction across street. Ruby was interested, but did not break heel. She did not bark or lunge. Soooo happy!!!!!
