AUGUST, affectionately known as Augie, has turned 20 and officially become the world’s oldest golden retriever.

Augie’s advanced age is, in fact, twice as long as her breed is usually expected to live.

August, who turned 20 in April, has outlived many dogs of her same breed. The average lifespan of a golden retriever is believed to be 10 to 12 years old.

GoldHeart Golden Retrievers Rescue helped the Tennessee dog celebrate her special milestone.

“There are many accounts of 17 or 18-year-old goldens, and even a few stories about 19-year-old goldens, but Augie is the first golden retriever to ever reach the big two-oh,” a blog dedicated to her birthday reads.

The dog was celebrated with a special cake and birthday scarf on her big day, with photos from her birthday party going viral since they were shared on the rescue group’s page.

According to the Pedigree age calculator, Augie’s age is the equivalent of 145 years in human years.

The elderly golden retriever was born April 24, 2000.

She has been rehomed twice but, at 14, found her forever home with Jennifer and Steve Hetterscheidt in Oakland, Tennessee, the United States.

“They figured that most people wouldn’t want such an elderly golden, but they had no idea of the upcoming journey they would be on with Augie,” the blog post adds.

Augie has lived a full life with her current human friends, who’ve taken her on many adventures in their campervan around the U.S.

According to her owners, she still likes her walks around the yard and enjoys cuddles and pats.

“Since she was diagnosed with some kidney issues when she was 14, she has been taking some supplements for her kidneys and joints,” Jennifer Hetterscheidt said.

“She also gets SQ fluids twice a week, which has helped her perk up quite a bit.”
