Ari loves playing with a toy, and after you throw it he happily brings it back and drops it at your feet. But when you try to pick it up he snatches it back. How do you fix this?
When a dog is doing an unwanted behavior the question to ask yourself is, what do I want him to do instead? The answer in this case was for Ari to simply wait for us to pick up the toy.
We actually taught him Wait a few weeks ago, and it means "be patient and something will happen for you" - like his food being put down, a door being opened, or a toy being picked up and thrown again. And sure enough, we threw a toy, Ari brought it back and dropped it, we asked him to wait, he let us pick it up, and we threw it again! No more racing for the toy. No more tugging. Play is now fun for everyone!
