Well, Schatzie's had hers now for a few days. Oh my goodness, I have to HIDE it as she freaks out and whines for wanting it so badly. (spoiled brat!!)
So, she has figured out that it makes her angry that the ball doesn't hold still, frustrates her to no end. So, she has learned now to place her entire body to hold the ball down. With doing so, she bit off part of the red bumble sticking up.

I was not a happy camper treating her like a kid saying, "Now Schatzie, you just DO NOT take care of your toys, you are forever DISTRYOING everything you have. You are such an agressive chewer and I wish you'd take better care of your things".
I amaze myself talking to her as if she's human. I am sure all she could understand was "blah blah blah Schatzie, blah blah toy, blah blah Schatzie".
All I have to do is turn that Bumble on and Schatzie goes insane.
I am sorry for the others Yorkie's who have not found it as facinating, maybe in time.
I know a post was sent out quite awhile ago about a plastic bottle being rolled on the floor, Yorkies all over loved it. Schatzie could care less. I was so disapointed, ha haaa..
