If I were a dog, I would be particularly concerned about a moving object. Think of all the fun I could have. There are 22 people chasing after that one thing, and I'm faster than all of them.
If I could get it, I could run all over the field and keep it away from them. I wouldn't have to bring it back. I could just keep on running until I got tired. Then I'd just drop it and run back to my lady.
