How Much Exercise Does Your Dog Actually Need?

Under-exercised dogs are destructive and noisy. Over-exercised puppies develop joint problems that last a lifetime. Both are common, and the right answer depends on breed type and age more than on size.

Rough daily guide for healthy adults

Working and herding breeds — border collies, malinois, kelpies, shepherds: 90 minutes or more, including mental work. These dogs need a job.
Sporting and gundog breeds — labradors, pointers, spaniels: 60 to 90 minutes.
Terriers: 60 minutes plus, with mental work. Small does not mean low energy.
Guarding breeds — boerboels, rottweilers, ridgebacks: 45 to 60 minutes of moderate work, avoiding high-impact repetition.
Sighthounds — greyhounds, whippets: 30 to 45 minutes with a short sprint. Famously lazy the rest of the time.
Toy breeds: 30 minutes, plus indoor play.
Flat-faced breeds: 20 to 30 minutes of gentle exercise only, in cool conditions, watching the breathing.

Puppies: the five-minute rule

A common guideline is roughly five minutes of formal exercise per month of age, once or twice a day — so a four-month-old puppy gets about twenty minutes. It is a rough rule rather than a law, but the principle behind it is sound: growth plates do not close until somewhere between nine and eighteen months depending on breed, and repetitive impact before that causes lasting joint damage.

Avoid long runs, jogging alongside a bicycle, repetitive ball chasing and jumping off furniture in large-breed puppies. Free play on grass at their own pace is different and is fine.

Mental work counts double

Twenty minutes of scent work, training or a snuffle mat tires a dog more than an hour of walking. For high-drive breeds it is not optional. If your walk cannot be longer, make it a sniff walk on a long lead and let the dog set the pace — sniffing lowers arousal and genuinely satisfies dogs.

The ball trap

Repetitive high-speed fetch with hard stops and turns damages joints and creates a dog stuck in a permanent arousal loop. Use the ball as one part of a varied routine, not the whole thing.

Seniors and heat

Old dogs need shorter, more frequent walks rather than one long one. In South African summers, walk before 8am and after 6pm, check the tar with your hand, and cut back sharply on hot days for every dog.
