Rescued dog vet care

On our drive back to San Antonio, Derek spotted this dog next to the road so we turned around to go find its owners & when we got up to her a car purposely swerved toward her & ran over her front left leg. It is snapped in a few different places. After an hour of looking for her owners, no one claimed her. So she is now in the truck with us headed back to San Antonio. So far we stopped at Walmart to at least get it splinted until we can get her to the 24 hour vet. We have no idea how much this is going to cost so I set 2000.00 just as a ball park figure incase she has to have surgery. We would greatly appreciate any support, shares and donations so that we can get this sweet baby taken care of.
