This is the most excited dog in the world. As he should be: This is Duffy, an Irish Terrier rescue dog. "He's had a lot of struggles with his health," owner Benjamin May says. "He developed diabetes and lost his eyesight."
But: "With medication we got his diabetes stable and he qualified for eye surgery to give him back his sight," Benjamin continues. "Here he is seeing my parents afterwards."
You know those videos where babies get cochlear implants and hear their mom's voice for the first time? This is kind of like that, but with a dog (and we love all videos that include a dog).
