How old is the oldest golden retriever living?

I cannot give you a specific age for the oldest golden retriever living. There isn't a central registry for dog ages, and records of the oldest living dogs are often anecdotal.

However, I can tell you that the average lifespan of a golden retriever is 10-12 years, but some can live much longer. There have been reported cases of golden retrievers living into their late teens or even early twenties.

To find out about the oldest golden retrievers, you might try searching online for articles on the topic, looking into dog breed forums, or contacting organizations like the Guinness World Records.
