Surgery for Rocky

My 5 month old puppy Rocky, was struck by a bicycle and now his right back leg is broken. The vet priced his surgery to be at least 2,000. Anyone who knows me know this little puppy is my baby. I adopted him from the Humane Society when he was 9 weeks old. It kills me to see my baby boy in pain. I really hate to ask for help but I am in desperate need. I am a college student and I simply can not afford this surgery.
