This guy should start selling this I'm sure many people would buy it. I would I'd just have it outside though.

ya would be cool. only if my dog was smart enough to use it though lol.

Lol I think it would take a while to teach them and it would have to be made of something rather resistant aswell 'cos the dog might try to attack it lol. But hey everything bought for dogs ends up being chewed anyway lol

fucking genius.

If it would shoot the dog instead of the ball I would buy it.

Lol when I was watching it I was thinking "imagine if the dog got caught in it somehow and was shot into the air" lol.

Sick. Best part is how the dog starts running as soon as the ball starts getting pulled back.

Nice

lol yes this is a good invention.
