This invention....well, it's a dilemma. I want to call the owner lazy, but the fact that they built the invention makes them very unlazy. The dog sure isn't lazy.
Here's the thing, I believe in bonding with your dog, so having them play with a machine over and over just makes it all seem less personable. Although it is very clever if you are a highly busy person and you dog is a highly busy dog...I suppose...
