A deaf and blind dog suddenly burst into life when she caught the scent of her owner's physician father, who she had not had contact with for more than a year because of the pandemic. In the emotional footage, Australian Shepherd Bitsy can be seen walking around the yard at her owner Hayden Kristal's home, in Pueblo, Colorado. As Hayden's father Steve Kristal, 64, approached, Bitsy, 5, was initially unaware of his presence – but all that changed once the shepherd caught a whiff of Steve's scent. Bitsy immediately began jumping on Steve and squealing with joy, instantly recognizing the man who she had shared a bond with for so many years before they were separated.
