Tumbles, who was born without his front legs, was rescued from the cold when he was just two weeks old, according to Friends of the Shelter Dogs in Ohio.

Tumbles has been able to move across the floor by balancing on his nose and back legs, but a veterinarian suggested he get a cart to help him build muscles in his back legs.

With the help of the Ohio University Innovation Center, they built Tumbles a cart using a 3-D printer.

He manages to get to his feet and push the cart along the ground - but he'll need hours of physical therapy and a few tweaks to the cart before he can run around on his own. Check the amazing story below.
