Help Lunabelle Run Again After Accident

We are raising funds for surgery for our 1-year-old Lab/Pointer mix pup, named Lunabelle. She is the sweetest dog with nothing but love in her heart. Sadly, she was struck by a vehicle during a white-out snowstorm here in Buffalo, NY. Thankfully, she is still with us, but we have recently found out that she will not regain function in her left leg. The vet said the best thing to do in her situation is to remove it. Lunabelle has got so much determination, she has already decided it will not stop her from being the happiest dog. It's only been a couple of weeks, and she is trying to run around and play with her brother Sonny. Unfortunately, the dead weight is getting in her way. It is apparent that removing the leg is the only way she can have the best life possible. We greatly appreciate any kind of help we can get. Estimate for surgery is $4500-$5700.
