- Give the dog a tennis ball
- Let him push it as far as it will go under any piece of furniture
- Next he will bark hysterically without stopping until someone gets it out
- Repeat, etc.
The only thing that stops Winston from playing this game is when a mysterious force causes the tennis ball to completely disappear.
From my experience, the only ones who truly enjoy playing are dogs. Thus I fear there would be some issues with marketing to a canine target audience for one important reason.
Dogs don't carry credit cards (thank goodness!).
