A dog in Tennessee has become the oldest known living golden retriever in history after celebrating her 20th birthday in April. The golden retriever named August, or “Augie”, who lives with owners Jennifer and Steve Hetterscheidt in Oakland, Tennessee, turned 20 on April 24. The couple said Augie was born in 2000 and had two previous homes before they adopted her when she was already 14. Most golden retrievers live between 10 and 12 years.
