Oldest dogs

The oldest verified dog (and several without strong evidence) is linked to the Australian Cattle Dog. This has 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 ("Verified") or Chilla's ("Unverified") should be regarded as uncharacteristic exceptions rather than as indicators of common exceptional longevity for the entire breed.
