Sometimes I don't want to play fetch with my dog, so I do this instead. And he loves it!
At my house, we drink a lot of Pepsi, so I never seem to run out of boxes. This is an easy, inexpensive way to keep your dog entertained.
Let your dog know he can get it and prepare to be entertained.
I think this is really funny to watch. It's kind of like a kong toy, and you can watch your dog discover new ways to get the ball.
Since the cardboard is destroyed easily, I suggest having several on hand :)
