The world's oldest living dog, a chihuahua named TobyKeith, breaks Guinness World record 

TobyKeith – no, not the singer but a chihuahua from Florida – broke the record for the world's oldest living dog.

 Born on Jan. 9, 2001, TobyKeith was 21 years and 66 days old on March 16 when Guinness World Records confirmed he was the oldest dog alive. 

"People can’t believe how good he looks for his age," the dog's owner, Gisela Shore, told Guinness.

She has had him most of his life and adopted him from a shelter when he was a puppy. Shore met the pup after an elderly couple surrendered him because they could no longer take care of the chihuahua.  

"I was introduced to a tiny tan Chihuahua. They had named him Peanut Butter. I later changed his name to TobyKeith," Shore told Guinness.
