Two legged dogs

A picture in the last issue of Fortean Times of a dog with no front legs intrigued me. The dog was said to have been born with just two legs, and to walk ably on its hind legs.

I wondered at first if the image had been manipulated, but it seems it's not the only able two legged dog out there. There's also Faith, who also lacks both front legs.

But Dominic the two legged greyhound seems even more impressive, because he has only one front and one back leg. And yet it doesn't seem to slow him down at all:
