Jerry just can’t get enough of chasing a ball. The problem is he always needs someone to through it for him, or does he? Luckily Jerry has a very smart owner he designed and built an automatic ball machine that fires the tennis balls for Jerry to go and chase. Once he’s retrieved the ball he simply drops it back into the machine and the game continues. It’s a great idea that’s been well engineered with excellent safety features to make sure nothing goes wrong. This is a great video that all dog lovers will enjoy.
