All Dog Breeds >>Health of Australian Shepherd

Morality

Results of a 1998 internet survey with a sample size of 614 Australian shepherds indicated a median longevity of about 12.5 years, but that longevity may be declining. A 2004 UK survey found a much shorter median longevity of 9 years, but their sample size was low (22 deceased dogs). The median life spans for breeds similar in size to Australian shepherds are mostly between 11 and 13 yrs, so, assuming the results of the UK study are not representative of the population there, Aussies appear to have a typical life span for a breed their size. Leading causes of death in the UK survey were cancer (32%), "combinations" (18%), and old age (14%).
