Reward doubles in case of dragged dog

ST. LOUIS -- A 5-month-old pit bull dragged along an interstate highway in St. Louis is making progress in his recovery. And a reward for the capture of the person responsible for the crime has doubled Wednesday to $5,000.

The puppy known as Trooper is eating and drinking normally. Veterinarians are confident they can save his badly injured right front leg.

The puppy was dragged behind a truck on Nov. 21 on Interstate 55. It happened without the driver's knowledge after someone apparently attached the dog's leash to the truck's trailer hitch.
