Below is a story of a bipedal dog name Faith

Faith, a bipedal female dog, was born in December 2002 with only three legs; two fully-

developed hind legs and a deformed front leg, which was amputated when she was 7 months old after it began to atrophy. Her owner, Jude Stringfellow, adopted Faith when the mother dog was found trying to smother the deformed puppy-- her son rescued the puppy and brought her home. Many people, including veterinarians, advised that Faith be euthanized. Instead, using a spoon with peanut butter as an incentive, Jude taught Faith to hop but Faith decided on her ow

n to walk; the family's corgi would bark at Faith from another room, or nip her heels to urge her to walk.
