I think this is so sweet. The doggie gets to walk again and have a loving life after the owner's abandoned the poor thing and left it to freeze in a cold basement!
This made me feel good cause the doggie seemed to be very affectionate and lovey! so why would the owners do such a thing? :-(
They basically gave him prosthetic paws because he froze them off. He was in a cold basement and his paws stuck to the floor.
This site has some more info about it and I think they have done the same with a kitty as well!
