 For example, a Beagle (average life expectancy 13.3 years) usually lives to around 12–15 years, and a Scottish Terrier (average life expectancy 12 years) usually lives to around 10–16 years.Two of the longest living dogs on record, "Bluey" and "Chilla", were Australian Cattle Dogs.This has prompted a study of the longevity of the Australian Cattle Dog to examine if the breed might have exceptional longevity.
