Bluey (long-lived dog)

Bluey was a female Australian Cattle Dog owned by Les and Rosalie Hall of Rochester, Victoria. She holds the Guinness World Record as the oldest verified dog to have ever lived. The record was briefly disputed by Bobi, but Bobi's certification was revoked by Guinness due to the lacking evidence, after veterinarians came forward challenging Bobi's claimed age. Additionally, Bluey's title was also challenged by many other dogs including Max, Chilla, Maggie, and Bella, though they were never verified.
