Thinking about the other dog being trained with Gertie. I'm thinking they might have a situation like Elwood and Jake. If I had sent them out for training, they could have walked Jake using a noodle for a leash. All you had to do to correct him was scowl and it would hurt his feelings. Elwood would have been double leashed and wearing a muzzle, and red tag. He was a handful to train, and took everything as a personal challenge. If you glared at him, he glared back. They only had a 6 mo. age difference, so it wasn't anything we did that made them so different, they just had their own personalities.
