Have you ever seen someone playing fetch with a dog and then they mime the throwing of the ball and then laugh when the dog goes running?
Yeah, don’t do that.
No seriously, don’t.
It takes a long time to earn your dog’s trust and, eventually, if this is truly important to you, it can be taught to the dog as a game. But, in general, this is just an asshole move that a dog just doesn’t understand.
So, don’t do it.
