(Las vegas)

My dog (boxer) got a hold of my tortoise o just got her she is like 8months old . I reacted pretty fast . Her shell is a little damage in the front edge there was no bleeding bit she is not coming out of her shell and she is moving .. How can I tell if she still alive or I want to know if it was possible that she could of die of shock?
