This Irish Terrier called Duffy was ecstatic to be reunited with his family after surgery to restore his sight. Last year, Duffy was found to be suffering from health problems and diagnosed with diabetes. His family struggled to control his blood sugar levels and Duffy went blind. After the diabetes was eventually under control Duffy underwent surgery to restore his sight. This video shows Duffy delighted to see his family again, and vice versa! Credit: YouTube/Benjamin May
