Meet Derby. He was born with small forelegs and no front paws.
A cart just wasn't giving Derby the full movement he so clearly craved.
But thanks to the kind actions of his foster owner Tara Anderson and the wonders of modern technology, he has been given a new lease of life.

Derby has now been adopted properly by Dom and Sherri Portanova, and judging by his Facebook page, is enjoying life a lot.
