One of my first yorkies, Channel, had an addiction just like that. She would sit and bark at us for us to throw her toy. It got so out of control that we just had to hide her toys when we got tired of throwing it. Channel did not care how big a toy was, she would try to pick it up. She would go after a basketball or anything round that rolled. One day she went after a watermelon we had sat on the floor. She was one silly girl. My only suggestion is to put her toys up and only let her play with them when you are ready. You should have chews available for her to chew on to keep her from getting bored. Good luck with her.
