Puppy Exercise Calculator: Minutes per Walk by Age

The rule of thumb most UK owners hear is five minutes of structured exercise per month of age, up to twice a day, until the puppy is fully grown. So about 15 minutes per walk at three months and 20 at four. Enter your puppy's age and the size it will grow to below and you get today's limit per walk, the daily total, roughly when the limit stops applying, and how it rises month by month between now and then.

One honest caveat before the numbers. The Kennel Club publishes the five-minute rule as a guide, but the PDSA says there is no scientific evidence behind it and prefers exercise tailored to the individual puppy. The sensible way to use it is as a ceiling for structured exercise: lead walks, training sessions and games where you set the pace. Free pottering in the garden, where the puppy stops when it is tired, does not need to be timed.

How the calculator works

It converts your puppy's age to months (a month is taken as 52 divided by 12, about 4.33 weeks), multiplies by five and rounds to the nearest minute. That is the limit for one structured session. With two sessions a day, the daily total is double that. The rule runs until the puppy is fully grown, which depends on size: around 12 months for toy and small breeds, 15 for medium, 18 for large and up to 24 for giant breeds. These are the same growth ages our puppy weight calculator uses, so if you are unsure which size band your puppy falls into, estimate its adult weight there first.

The dates in the table are approximate and count forward from today. A crossbreed with one large and one medium parent is best treated as the larger size, because the risk of over-exercising a still-growing dog is greater than the risk of under-exercising one for a few extra months.

What counts as structured exercise

Count anything where you decide the pace and the puppy cannot simply stop: walks on a lead, training classes, fetch, tug and lengthy play with an older dog. Do not count sniffing around the garden or wandering about the house. Avoid running alongside a bike or jogging with a puppy, long flights of stairs and repeated jumping in and out of the car, as all of these put load through joints that are still developing.

Short walks do not have to mean a bored puppy. Letting it sniff and take in a new route uses its brain as well as its legs, and at this age meeting people, dogs, traffic and new surfaces calmly matters more than distance. Our guide to puppy socialisation classes explains what a good one looks like.

If someone else walks your puppy

A group walk lasting an hour is well over the limit for most puppies. Ask a walker whether they offer short solo puppy visits instead, and give them the figure from this calculator. Our dog walker cost calculator helps you budget for regular visits, and in warm weather check whether it is too hot to walk your dog before any session.
