The Charleston Animal Society has offered a $1,000 reward to anyone with information leading to a criminal conviction of the person who shot Chance, a puppy its veterinarians have been treating.

The 7- to 8-month-old hound mix was found last week near Ravenel. Its front legs were riddled with shotgun pellets and infected. A resident found the dog, but authorities have no information about how it had suffered the injuries.

Veterinarians suspected that the puppy had been hit with birdshot from a close-range shotgun blast. Chance was recovering, but was in danger of losing one of his front legs.

Maj. Eric Watson of the Charleston County Sheriff's Office said animal control deputies were trying to figure out where Chance was shot. He noted that the dog's rescuer had found him near Highway 17A, which could mean that the site was close to Colleton County.

Spokeswoman Kay Hyman said Thursday that the society would offer the reward and field tips.

Anyone with information should contact Aldwin Roman, the society's manager of anti-cruelty and outreach, at 843-329-1545 or aroman@charlestonanimalsociety.org.
