In the past, many animals lacking arms and legs could only wait to die. Even if they were adopted by well-wishers, they could not walk or eat normally. With the development of prosthetic technology, especially after the emergence of 3D printing technology, many animals can be fitted with custom-made prostheses and live like healthy animals.    

This dog is named Naki'o. He was abandoned by his owner since he was a child. In the cold winter,he froze his leg and had to undergo amputation of his limbs. Since then, he can no longer run freely. The owner who adopted it can't bear to see Nakio lose his freedom. Finally, a 3D printed prosthesis was installed for it. Now Naki'o can not only walk freely, but also swim. In fact, there are many cases like this. 3D printing technology has allowed humans to bring new vitality to these disabled animals.
