The other day, I put the retractable leash on Flash and we went to the back yard to train. Flash loves it. He doesn't think of it as training, he things we are playing. Anyway, I threw a tennis ball and, of course, he went after it. Then I tugged on the leash a little and asked him to bring it back. And he did! So we played this game for awhile, interspersed with a cookie from time to time. He was having fun. He would bring back the ball and drop it into my hand and I would reward him either with a cookie or with throwing it again.
Then I took the leash off and played the same game. Whereas, formerly he would just run away with the ball, this time he actually brought it back! Time after time, he would get the ball, bring it back, drop it into my hand, and get a cookie or get to chase the ball again. Yea! Good dog.
Trainer Rachel was right. You just have to repeat the task again and again until he gets it and wants to do it. I know it will take many more days of working on this exercise before he will forget about taking the ball away instead of returning it, but at least we had a breakthrough. I'm happy.
HAPPY THANKSGIVING
