Medium breed

How long do Australian Cattle Dogs live?

A Australian Cattle Dog typically lives 12–14.6 years, from the age-conditioned veterinary life tables behind the Tailmates longevity score. Always a range, never a date.

The curve, not a countdown

Already 2+ years old? The outlook is better than subtraction.

These numbers are conditional on the age your dog has already reached. A dog who’s made it to midlife has cleared the early risks that pull the breed average down. So the honest answer is more than “lifespan minus age.”

Walking needs

How much should you walk a Australian Cattle Dog?

Around 60–90 minutes a day — most medium breeds happily take more.

Working breed: Australian Cattle Dogs were bred to work all day. Plan for the top of that range, plus play, sniffing, or a job to do. A bored Australian Cattle Dog invents their own work.

Band-level guidance, not a prescription. Age, health, and your vet’s advice come first.

Walks on the curve

What daily walks do to the longevity math

In the Tailmates model, a 28-day rolling window of active minutes feeds a saturating curve, the first minutes matter most, and it moves the estimate up by at most +0.5 years, never down. Bounded on purpose: activity has no published year-delta, sick dogs simply move less, and a walk you forgot to log looks exactly like a walk you never took. For a steady daily habit:

The bigger walking payoff is indirect: lean body condition, the strongest modifiable lever in the model. For a medium breed like the Australian Cattle Dog, ideal body condition reads +0.5 yr (capped at the +1.8-year effect from the Kealy lean-feeding trial), while carrying extra weight reads -0.8 yr and obesity -1.5 yr. Daily walks are how most dogs stay on the right side of that line.
