How much exercise does a dog actually need?

It varies enormously by breed, age, build and individual temperament, so a single figure is not meaningful. What holds generally is that most dogs need more than they get, and that mental exercise is undervalued relative to physical.

As a rough orientation, many adult dogs do well on somewhere between half an hour and two hours of activity daily. Working breeds bred for sustained effort sit at the upper end and sometimes beyond it. Short-faced breeds often need considerably less and can overheat easily, particularly in warm weather. Giant breeds and very small breeds have their own constraints.

Age matters in both directions. Puppies should not be over-exercised while joints are developing, and a commonly cited guideline is a modest number of minutes per month of age, twice daily, though breed guidance varies. Older dogs often need shorter, gentler and more frequent outings rather than none.

Mental stimulation is the part most often missing. Scent work, training, puzzle feeders and simply allowing time to sniff on a walk are tiring in a way that distance alone is not. A dog permitted to investigate at its own pace typically returns more settled than one marched briskly for the same duration.

The signs of insufficient exercise are recognisable: destructive behaviour, restlessness, excessive vocalising, difficulty settling, weight gain. The signs of too much are also real, including reluctance, stiffness and lagging behind.

Where there is doubt, particularly for a breed with known joint or breathing considerations, or for a dog with any existing condition, a vet is the right source for a specific plan rather than a general article.
