The oldest dog lived 29 years!

Bluey was an Australian cattle dog born on June 7, 1910. He was owned by Les and Esma Hall and lived in Rochester, Victoria, Australia. Even though the record is unverified, he is believed to have lived until November 14, 1939 making him 29 years 6 months and 12 days old when he passed. 

He is in Guinness World Records as officially being the world’s oldest dog and Guinness says the source is reliable. Australian cattle dogs are also known as blue heelers or red heelers. 

They were originally bred in Australia for herding cattle over rough terrain. Thomas Hall crossed cattle dogs used in Northumberland and wild dingoes that he’d tamed to create the Australian cattle dog. After Hall died, the breed became available to the public. The dogs are very energetic, quick intelligence, and independent. 

They work well under structured training so long as it is interesting and challenging to them.
