When I was a child, I had a puppy named "poppy". One of her favorite play was catch ball. But the problem was when she caught the ball with her mouth, because she didn't want to set a ball free and persistently biting it. Every time I played with my puppy, I had to take a ball away from her mouth by force, and it was really tough work.
Now, as a college student, I learned how to train the dog with the positive reinforcement. If I knew this before, my puppy and I would have a more fun play.
Positive reinforcement is presentation of a stimulus that strengthens the probability of the behavior. With treats and praise, it is easy to train the dog. Importance thing to remember is the shaping behavior. If the teaching certain behaviors takes some time, reinforcing something close to the desired technique then gradually requiring more to achieve the final technique.
One of the dog trick that I wanted to train my puppy was "Play Dead" This fascinating trick can be trained easily with positive reinforcement. To train this trick with the shaping behavior, initially reward dog for lie-down, then for staying motionless.
