Guess I have another one

A week ago, I went to take my dog on a long walk (there’s a trail by house that is rarely used) and he went wild for some reason. So much so that he broke his harness and dashed towards the creek (remember, he’s a pit bull so he has the strength, but this wasn’t normal behavior for him). I was confused and worried so I tried to go after him, but he came back with what I thought was a rat, but turned out to be a tiny chihuahua covered in mud. It wasn’t breathing so I tried CPR on it and it luckily worked. I wrapped it up in my sweater and rushed her to the nearest open animal emergency center which was just around the corner from my house. This past week, my dog has done nothing, but try to get to her. It surprised me because he remembered the way to the animal hospital and every time I tried to take him on a walk, he would try to go to her. Well, today is his lucky day. I went back for her, and when he gets back on his walk with my fiancé, he’s gonna be one happy pitty. Poor little girl is scared, but she seems to have calmed down after I put a warm blanket on her. They said she’ll be fine and to just keep an eye on her. She doesn’t have any broken bones, she’s on antibiotics, and they said her lungs have cleared out too. What should I name her?
