Buster's vet bills

Our little Buster has an injury that we can't quite put our finger on. Our vet says that he has ataxia (impaired coordination) in his back legs resulting from some injury or disease in his lower back. We are scheduled to travel down to Va Tech in August for a neurological consultation that will most likely include a MRI and/or surgery. Obviously, all of this adds up quickly. We know that times are tough for everyone but I figured we might as well try and give this a shot. If you feel inclined to help us out with his vet bills, we would be incredibly gracious.
