Size-adjusted vet chart, Australian Cattle Dog lifespan range, life stage and a shareable ID card.
How long do Australian Cattle Dogs live?
Breed clubs quote 12 to 16 years. Bluey, an Australian Cattle Dog, held the Guinness record at 29 years and 5 months for decades. Medium-breed aging: a 13-year-old Heeler is roughly a 78-year-old human.
For context, the size-class ranges we use across all breeds: small dogs 12 to 16 years, medium 10 to 14, large 9 to 12, giant 7 to 10. Individual dogs beat their breed's range all the time; the range is where the odds sit, not a ceiling.
What decides a Australian Cattle Dog's lifespan
Eyes and ears
Progressive retinal atrophy (DNA-testable) and congenital deafness (BAER-testable in puppies) are the breed's known hereditary conditions.
Hips and elbows
Dysplasia occurs; lean weight and scored parents.
Injury
A dog bred to work cattle takes risks: kicks, roads, cliffs. Most early Heeler deaths are accidents.
A working brain
Under-worked Heelers invent jobs, usually destructive or self-injuring. Daily mental and physical work is a welfare requirement.

|---|---|---|---|
| Puppy | under 1 | 0 to 15 | Growth, vaccines, socialisation window |
| Young adult | 1 to 3 | 15 to 32 | Adult body, teenage brain; habits and weight set now |
| Mature adult | 4 to 10.5 | 32 to 62 | Prime years; annual exams, dental care, lean weight |
| Senior | 10.5 to 16 | 62 to 87 | Twice-yearly exams and bloodwork (AAHA) |
