Some common problems people face with fetch are over excitability, which can be solved with the first suggestion, and playing keep away. The best way to deal with a dog who wants to play keep away is to refuse to play the game. If the dog won’t bring the toy back or drop it, end the game, turn your back, go inside. The dog only gets to play if he plays by the rules. Using two toys will often help a dog learn that he has to give up the toy in his mouth to get you to throw the other toy.
