With the average life span of a dog ranging from 7 years - 16 years depending on breed, would we want our dogs to live this long? I wonder how different the dog industry would be. If they were happy and healthy, for me the answer is yes.
Max (9 August 1983 – 18 May 2013) was a beagle, dachshund and terrier mix who lived 29 years and 282 days.
In August 2009, the Telegraph reported that Max had veterinary records proving his age and that at 29 he was the world's oldest living dog. He was 3 years older than Pusuke a Shiba Inu who, at 26 years of age, had previously been considered the oldest living dog.
On May 15, 2013, the Guinness World Records organisation approved a claim made by Janelle DeRouen for Max to be recognized as the World's Oldest Dog. However, just three days later, on May 18, Max died of a Tonic–clonic seizure. If Max had lived to the following August, he would have been the first dog known to reach 30 years of age.
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.
