Rescue Pup needs emergency care

Hi my name is Robin, a kind lady found this dog running loose in the street at 1:30 Am, she isn't able to keep the dog and wet haven't been able to locate the owners, I've agreed to take in the dog until we can find the owners, unfortunately it looks like the dog was either injured while loose or possibly sustained an injury by it's owners in which case we will not be returning the dog. The tip of her tail appears to be missing, she's limping and either has a deformed spine or some kind of hip injuy. X-rays will give us a better idea of what's happening with the dog. The vet I take my other animals too doesn't have an appointment until Thursday and will call me if there's any cancellations. (CROSS YOUR FINGERS) I've gotten a quote between $700 and $1,000 for all of the treatment that could possibly be needed. Any funds left over will be donated to dog rescues for care for other animals. It takes a village to help all animals I really appreciate any help that you can provide. Thank you in advance and please hug your fur friends and families for me. ♥️
