Help Harley Recover from Vicious Dog Attack

Hi, my name is Dave. I am trying to raise funds to help cover Harley's, my 12 yr old senior dog's emergency surgery and vet bills. Harley is a rescue dog, that someone abandoned in the woods at 9 weeks old. A couple weeks ago, while walking the same street as we have done for years, since he was a 12 week old puppy, we were attacked by 2 much bigger dogs weighing 100 lbs or more a piece. Harley weighs only 52 lbs. They were twice his size. My dog was leashed to me, the other dogs were not. They were running free, and their owner was no where around. They immediately attacked. One dog had him by the neck, the other had him by the rear end and they were pulling him in opposite directions, like a tug of war toy. They shredded pieces of flesh from his body as I was frantically trying to fight them off. The more I fought them, the more they tore him apart. You can't even imagine the trauma to his body and how i felt watching my boy get torn in pieces. Worst experience of my life! Harley is a very friendly dog that loves making new friends wherever he goes. He did not deserve this. The vet bills so far are pushing $4,000 and we are far from over. Thanks for whatever you can do.
