True or False: The world’s oldest recorded dog lived over 25 years.

The story behind the answer

True. The oldest reliably recorded dogs have lived well past 25 years. Bluey, an Australian Cattle Dog from Australia, reached 29 years 5 months (a long-standing Guinness World Record). More recently, Bobi from Portugal was reported to have lived over 31 years, though that claim has been under review—either way, it shows some dogs can surpass 25 by a wide margin.

For context, most dogs live about 10–13 years, with smaller breeds tending to outlive larger ones. Genetics, a healthy weight, regular vet care, and good dental health all support longevity. Memory tip: think “Bluey nearly thirty”—if a dog can get close to 30, then “over 25” is clearly true.
