Bluey (7 June 1910 – 14 November 1939) was an Australian cattle dog owned by Les and Esma Hall of Rochester, Victoria, Australia, which, according to an anecdotal report, lived 29 years, 6 months and 12 days, but the record is unverified. Bluey held the world record for the oldest dog, according to Guinness World Records, who cite the anecdotal reports as being "reliable", until February 2013, when Max took over.
Bluey's record age, along with that, also unverified, of an Australian Cattle Dog - Labrador mixed breed dog named "Chilla" reported to have lived to the age of 32 years and 12 days, 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. The study concluded that while Australian Cattle Dogs are a healthy breed and do live on average almost a year longer than most dogs of other breeds in the same weight class, record ages such a Bluey's or Chilla's should be regarded as uncharacteristic exceptions rather than as indicators of common exceptional longevity for this entire breed.
