Meet Duffy, an Irish Terrier, that lost his eyesight due to diabetes. After medication was able to stabilize his diabetes, he qualified for a surgery that would give him back his sight.

Duffy is a rescue dog that has overcome several health issues, but after a recent surgery that gave him back his vision he seems to be just fine. Listen to the sounds this wonderful pup makes once he recognizes his family. To say that he is excited to see his family again would be an understatement.

This reassures me that dogs truly are "man's best friend."
