WATCH: Tumbles the two-legged puppy gets his own tiny wheelchair

The feel good news story of the day features Tumbles.

He is a tiny (legit the tiniest) shelter puppy ever. He was born with only two legs, but now he is on the move after recently being outfitted with a custom 3-D-printed wheelchair. 

A video capturing the pint-sized pooch’s first steps, shows the little guy making big strides while in the care of Friends of the Shelter Dogs in Ohio. 

The pup was taken in by the shelter when he was only two weeks old at the time.

“We thought he wouldn’t make it,” Karen Pilcher, who serves as the group’s rescue coordinator and now Tumbles' foster mom, told ABC News.

Now look at him! Amazing. 

His first steps obviously took a lot out of the little hero because the shelter also posted a snap of Tumbles after his adventures on their Facebook page. 

We can’t deal, sorry.

Oh, and if you thought the story couldn’t get more adorable then you should also know that Tumbles is going to need a different wheel chair: because he is too small for the current one in use.

“I think we'll definitely be able to have a working model,” Joe Jollick told The Huffington Post. Joe is the lab director at the Ohio University Innovation Centre. 

“The challenge is getting the dog to use it and not try to sneak out of the straps and (him) learning to use his back legs correctly because right now he's just pushing himself on his chin.”
