This potentially heart-breaking story has the happiest of endings.

YouTube user Benjamin May shared this video of his Irish terrier, Duffy, seeing his family after eye surgery. Duffy was diagnosed with diabetes shortly after he was adopted, and it robbed him of his eye sight.

In this video, we get to see Duffy seeing the people that he loves so much for the first time since he was stricken with blindness. The surgery was only able to be performed after Duffy's owners got his diabetes under control.

It looks like Duffy is going to be living a long, healthy life with his people.
