How much exercise does a dog need? Reading energy, age and build

There is no single number — and why

PDSA's exercise guidance (opens in a new tab) lists what actually moves the figure: breed, age, health, fitness, and personality. Two dogs of the same size can need very different amounts — a number on a chart is a starting guess, and the dog's own response is the measure.

Breed background is a real clue, but only as history. The AKC's guide to the seven breed groups (opens in a new tab) explains that each group was developed for a job — herding, retrieving, guarding, companionship — and that history hints at the energy budget a dog may bring. A herding-type dog often arrives expecting work; a toy companion was bred for laps. Our breed-groups guide goes deeper on what group traits do and don't tell you.

Rough ranges by size, age and type

For orientation only: PDSA notes that some breeds need a minimum of one to two hours of exercise a day, and that working breeds can need significantly more. Its guidance also treats walking as a daily fixture — most dogs need at least one to two walks a day unless a vet advises otherwise. Those are ranges for typical healthy adults of a type, not a quota for your dog.

The most useful reading is the dog's: a dog who comes home and settles is probably somewhere near enough; a dog still ricocheting off the furniture an hour later may need a different kind of output — and a dog who flags halfway may need less, or a vet visit.

Puppies and seniors: protect joints, keep it gentle

While a dog is still growing, PDSA advises introducing exercise slowly to protect developing joints — several short, gentle outings and free play rather than long hikes or repetitive fetch. The quick starts and sudden stops of thrown-toy games strain joints, so PDSA advises avoiding them for dogs that are still growing, elderly, injured, arthritic, overweight, or prone to joint problems.

At the other end of life, the guidance flips the order rather than the activity: PDSA's senior exercise advice (opens in a new tab) keeps exercise regular and gentle — little and often, shorter routes with rest stops, scent games and indoor sessions when the weather turns. Older dogs still need to get out every day to sniff and stretch; they just do it at their own pace, and the vet should hear about any change in mobility or enthusiasm.

Flat-faced and heavy dogs: watch effort, not just distance

Distance is a poor ruler for dogs whose bodies work harder. Flat-faced (brachycephalic) dogs can struggle to cool themselves and breathe hard sooner, so shorter outings in cooler parts of the day suit them better. Heavy dogs carry extra load on every joint, and PDSA's exercise guidance is direct about the next step: if you're unsure how much exercise your dog needs, or you're worried about their weight or fitness, ask your vet — a plan beats a guess.

For dogs who enjoy it, swimming earns a special mention in the same PDSA guidance because it exercises without pounding joints — with the usual water-safety checks, and a vet conversation first if joints are already a concern.

Signs a routine needs adjusting (and who to ask)

Adjust in both directions. Restlessness, chewing, and rough play indoors can signal a dog with unused energy — PDSA notes fit, active dogs are less likely to develop behaviour problems. In the other direction, lagging behind, lying down mid-walk, stiffness afterwards, or losing interest in going out suggest the routine is too hard for this dog right now.

Making walks count: sniffing is part of the walk

A walk is more than distance. PDSA splits them usefully: a brisk walk burns energy, while a slow, meandering sniffing walk does the mental work. Training minutes, play, and puzzle feeders all count toward a settled dog — though play doesn't replace the walk itself.

Match the outing to the weather as well as the dog — our weather and paw-care guide covers heat, cold and salted pavements. And if you're still learning to read whether the dog is enjoying themselves or just coping, the body-language guide shows what to watch. Photographing the dog at rest and mid-walk is an easy way to notice the difference — a photo observation describes what's visible in the frame, including the dog's build and activity — readings are AI-generated and provisional, so treat them as a prompt to look again, not a verdict.

A useful handoff: Start from the dog in front of you — their background, age, build, and how they finish a walk — and let the vet, not a chart, settle the questions that look like health.
