"The dog, a female Maltese and terrier mix, is between 9 months and 1 year old... Popcorn has an extra, or supernumerary, leg on her left back side. It is about 80 percent complete, with a femur, a tibia and one toenail. The other leg is normal, but it has been pushed to the side by the extra bones... Because of the unusual bone structure, the veterinarians may end up removing both back left legs, leaving the five-legged dog with just three."
