Peggy Leg(!) the chihuahua was born without a foot, and was destined to have her leg amputated because its weight put so much pressure on her spine.
Instead, Peggy Leg soon will be the "world's smallest bionic pet" -- she'll be fitted with a titanium prosthetic foot by researchers at North Carolina State University, who are doing research on artificial limbs that they hope someday to use on humans.
"They were looking for just the right small dog to do this titanium implant," said Enchantment Chihuahua Rescue's Mary Jewell, who adopted the pooch when she was five months old. "When we were told about this program it was unbelievable. It was like, 'Oh my gosh, she is going to be a bionic dog with a bionic leg.'"
