Australian cattle dog owned by Les and Rosalie Hall
Bluey (7 June 1910 – 14 November 1939) was a female Australian Cattle Dog owned by Les and Rosalie Hall of Rochester, Victoria. She previously held the Guinness World Records as the oldest dog to ever live, until being surpassed by Bobi from Portugal in 2023.[1][2]
Longevity
According to Guinness World Records, Bluey (1910–1939) lived to 29 years, 5 months, before being euthanised. At that time, she was the oldest-lived dog ever verified.[3]
Three owners had also made claims for longer-lived dogs—Max, Maggie, and Bella—however, these claims have not been independently verified.[4][5]
Bluey's age, along with that of "Chilla", a Labrador Retriever and Australian Cattle Dog mix reported to have lived to the age of 32 years and 12 days,[6] prompted a study of the longevity of the Australian Cattle Dog to examine if the breed might have exceptional longevity. The 100-dog survey yielded a mean longevity of 13.41 years with a standard deviation of 2.36 years.[7] The study concluded that while Australian Cattle Dogs do live almost a year longer than most dogs of other breeds in the same weight class on average, the cases of both Bluey and Chilla should be regarded as uncharacteristic exceptions rather than as indicators of common longevity across this entire breed.[7]
