It still curls up because of the way she dislocated it. She just has a little kink in it and since she has lots of hair on her tail you really can't tell. I am thinking she might have done it when my uncle's dog was staying with us. He is a 115 lb golden retriever and she loved playing with him. She weights 4 lbs. So that is the only thing I could come up with. She seems fine now though. Thanks for all the get wells everyone!
