Thank goodness people like this exist. After reading that a baby Chihuahua-terrier with five legs was about to be sold to a Coney Island sideshow, Charlotte woman Allyson Siegel stepped in. She paid $4,000 for the deformed puppy -- a grand more than the original offer, plus the hefty cost to have the pup's extra leg removed. (Poor thing's tripping over it.) Seigel explains her motivation: "Don't do to animals what you wouldn't do to your kids." How about that for a happy ending?
