Ready to roll: A pit pull puppy who couldn’t walk due to a crippling birth defect has now been likened to the sprightly-footed tap dancer Fred Astaire after undergoing reconstructive surgery .

Flashback: The rescue pup was born with a deformity which caused his front to legs to be bent backwards at the knees - as a result, he was forced to crawl around on his joints . Commenting on Roscoe's progress his foster owner, Laurel York, told WLOS-TV: 'For the first couple of days he was really wobbly on his stilts. 'But [now] he's kinda like tap dancing like Fred Astaire.' Dr. David Crouch, who operated on Roscoe, said he's been impressed by the pup's swift turnaround. Recalling his pre-surgery appearance, the vet said: He was left with little flippers and trying to walk on the tops of his wrists and created bloody sores.' It's hoped in around three to four months’ time Roscoe will be fully healed and ready for adoption.
