Derby’s front paws were deformed from birth

He could barely walk, and often scraped or cut himself

He was going to be euthanized, but a no-kill shelter decided to save him

And when he got his 3d-printed prosthetic legs, he was off like greased lightning!

It all started with his foster mommy Tara Anderson, who works at 3D Systems

They took CT scans of Derby’s elbows and designed some custom prosthetic legs

The prosthetics will start low and get bigger as Derby gets used to them

Derby now lives with Don and Sherry Portanova
