saving honey

honey loves to dig out of our backyard and explore the neighborhood, but when she got out this time she got hit by a car, and has a dislocated hip, when we took her to the vet they told us that they couldn't put it back in place, and it kept popping out. surgery to fix is to expensive so the next thing we could do is amputate it, it's a few hundred dollars less but still very expensive. anything will help. i don't want to have to put my dog i grew up with to sleep.
