Puppy Born with 6 Legs in Oklahoma Doing Surprisingly Well

Here's a verrrry good girl with a little extra pep in her steps ... she was born with 6 legs but veterinarians say the pooch is miraculously beating the odds.

This newborn Aussie-border collie mix named Miracle but who also goes by Skipper was born in Oklahoma City and taken to a vet after she was rejected by her mom. Vets at Neel Veterinary Hospital say she's nothing short of a miracle because she's survived longer than expected. The pup was 4 days old at the time the pic was taken.

And get this ... the vets say Skipper has duplicate organs basically from her waist down, and they're all functioning. There's no published research showing another dog with this condition born alive.

Skipper has congenital conjoining disorders called ... monocephalus dipygus and monocephalus rachipagus dibrachius tetrapus ... that's science talk for 1 head and chest cavity but 2 pelvic regions, 2 lower urinary tracts, 2 reproductive systems, 2 tails and 6 legs, among other things.

All things considered ... Skipper does have some positive signs going for her. The vets say her organs appear to be in great condition and she's peeing and pooping like a normal doggy, She's also very strong and growing appropriately so far.
