Scientists have managed to give a six-week-old puppy a new lease on life.

Tumbles the terrier mix puppy was the runt of the litter and wasn’t able to get the milk he needed to grow properly. Born without his two front paws,his quality of life was immediately diminished for a puppy that had a lot of love to give.

He was rescued by the Friends of the Shelter Dogs (FOSD) in Athens, Ohio.

“We decided that he really needed extra special care and to be bottle-fed so he could become strong and healthy,” said FSOD President Angela Marx.

A local couple saw Tumbles picture and wanted to help the shelter design a 3D printed wheelchair for him.

“[The couple] came up with a design and contacted the Ohio University Innovation Center for help in creating it using their 3D printer,” Marx said.

Marx talked about Tumbles and how the wheelchair has provided him with new opportunities to explore and be a happy puppy.

“He’s a little sweetheart and doesn’t act as if he has any limitations,” she added.

“Since he is so little and still growing he needs to learn how to walk properly. Once the wheelchair is properly fitted he will need to go through physical therapy.”
