While fetch is a classic game, for some dogs it’s a trick that doesn’t come naturally. It can become pretty frustrating when your dog won’t cooperate at play time.

Watch this tutorial to see how you can get your dog interested in fetch in the first place, and then actually learn how to play fetch properly.
