I couldn't stop laughing when I read your post because my yorkie she is only 2 months gets a head start and then runs and jumps into the bed or couch till u pay attention to her and she does it over and over and it is the funniest thing I have ever seen. It's their personality they are playful and want u to know it. Maybe if you really don't want to play try just walking out of the room or take the toy and don't throw it, but I know when u see that cute little face you just have to throw it. I can't believe these dogs are so playful I have always thought litttle dogs to be serious and mean. They actually the best thing u can have around especially when u need some cheering up.
