Thanks guys. Nah she don't kick it under cars. She doesn't go outside. If she does, she kicks it at the front door. But our front door is not by the curb. We live in the back house in a 2 unit lot. So it way in the back.
It's like you know if your dog is stupid or not. She might of gotten hurt in an accident. But I don't think she is stupid to hurt herself that bad.
She really cant lick it so we didn't buy her that "thing". If she starts biting, I will have to buy one.
I will post updates. Thanks for your concerns and ideas.
