Pretty much all puppies have the ability to melt your heart. But Tumbles here really takes things to the next level.

Tumbles is a six-week-old terrier-beagle cross. And the adorable little rescue dog came into this world with a pretty hefty challenge: he was born without front legs.

Fortunately, we live in amazing times. Case in point: the wonderful folks at the Ohio University Innovation Center recently used a 3-D printer to create a tiny, fully-functional wheelchair for the wee puppy in need.

The amazing device took 14 hours (!) to print, and it fits Tumbles like a glove. Check out the fitting session below, and prepare to have your heart warmed.

Now that's a sweet set of wheels.
