Stella`s Vet Bills

Hey guys!
My brother and sister law have a beautiful little pup named Stella who is a little worse for wear.
Stella went missing a few days ago and we didn't think she was coming home. Luckily she did, but unfortunately she is not in the best shape. We assume she chased after something, got lost, and probably got hit by a car. She has one broken leg and one fractured leg. She has what we assume is road rash on her belly from dragging herself home.  She has to go in to surgery the next couple of days and it's going to cost alot of money. Any help will be greatly appreciate no matter how little. She is the sweetest dog you will ever meet and wouldn't hurt a fly. We just want to see her feel better and back to her normal hyper self. Thank you guys for all the help. ❤️
