Meet Robbie the Shetland Sheepdog. He's a good dog, but he has Cushing's disease, so his back paws have been problematic. His owners feared they would have to put him down, but instead found a better solution: robotics!
Look at how majestic he is now.
LOOK AT HIM!!!
I don't say this very often, but Robbie isn't just a good dog: he's a great one.
