The owner of the world's oldest dog has shared the secret behind his long life. Saying he is the product of good genes, a healthy diet, daily exercise, and love. 

Gisela Shore, 55, from Greenacres, Florida, celebrated her now-famous Chihuahua TobyKeith's 21st birthday on January 9. Guinness World Records confirmed him to be the oldest living dog in the world. A few months later, on March 16. 

'My vets tell me that genetically, he's just perfection,' she told Good Morning America. Crediting his continued health to diet, exercise, and a lot of love.' 

'We have a second floor to this house, and he is up and down those stairs probably 30 times a day,' she said of the active pup. Whose diet consists of vegetables, rice, and chicken. 

What does T. Keith do on a typical day?

On a typical day, TobyKeith wakes up at 6:30 a.m. and takes his first trip outside. Before getting his first snack of the day, according to Guinness World Records. He isn't allowed sugary treats, but his favorite snack is a slice of turkey.

When he isn't running around the house. He enjoys short walks and curling up next to his owner's workstation. 

Shore a lifelong animal lover. I started to suspect he was the world's oldest dog after his milestone 20th birthday in 2021. The average lifespan of a Chihuahua is 12 to 18 years,

'When he turned 20 years, everyone’s reaction was, "Wow!" 

'My friends and family thought he was the oldest dog they knew about,' she told Guinness World Record. 

The puppy does have a heart condition, but that isn't stopping him from living his best life. She also showers him with love, which includes pampering. 

What did he win?

In honor of being named the world's oldest dog, he was treated to a bath. A pedicure, and a car ride. 

Toby Keith has been living with Shore for the past two decades. After she adopted him from a local animal shelter when he was a few months old. 

'I was a volunteer at Peggy Adams Animal Rescue. One of the employees told me about an elderly couple trying to surrender a puppy. Because they could not take care of him any longer. 

'I met with the elderly couple and was introduced to a tiny tan Chihuahua. They had named him Peanut Butter. I later changed his name to TobyKeith.'
