Rescue dog Duke is running free thanks to 3D 'super leg'

When he was rescued, Duke almost had to have his leg amputated.

The Irish retriever was born with a birth defect in his front right leg and could hardly walk.

But now, thanks to Swansea company CBM, he is walking and running after they made him a 3D printed leg.

Duke, who lives in Bristol with his owners, is having a great time!
