Bluey, the Australian Cattle Dog.

The oldest dog on record was an Australian cattle dog named Bluey.

Bluey was owned by Les and Esma Hall in Victoria and was born 7th June 1910. He passed away 14th November 1939 at the ripe old age of 29 years and 5 months. In human years, that is more than 160 years old!

With Bluey's record ago and also the unverified ago of an Australian Cattle Dog mixed with a Labrador (believed to have lived over 32 years!) prompted an investigation into the Cattle Dog. The study was discover whether the breed may have exceptional longevity and took over 13 years to complete. The conclusion of the study found that Australian Cattle Dogs are quite a healthy breed and on average lived almost a year longer then most other similar breeds, though the record ages prior were simply uncharacteristic exceptions and a rare case.
