Pup Gets Life-Changing Surgery After a Lifetime of Crawling North Carolina pup underwent surgery to fix his deformity last week.

 -- A rescued pit bull has become a "tap dancer," in the words of his owner, after having reconstructive surgery to fix a rare deformity that left him only able to crawl.

Roscoe, a pitbull, was born with a deformity that left his front legs partially bent backwards under his wrists, according to ABC News affiliate WLOS-TV in Asheville, North Carolina. As a result he was forced to walk on his wrists, with the front part of his legs bent backward like "flippers."

Dr. David Crouch, a vet from Asheville, was able to help Roscoe walk by performing surgery to fix the deformation.

He was "trying to walk on the tops of his wrists and created bloody sores," Crouch told WLOS-TV.

To pay for the surgery the the Asheville Humane Society in North Carolina raised more than $3,000 for the pup.
