Most published guidance uses time rather than distance - and with good reason. A Springer Spaniel will cover twice the ground of a Basset Hound in the same 40 minutes. If you are planning a specific route and want a rough conversion, figure on 20 to 25 minutes per mile at a relaxed walking pace.
The short answer: most adult dogs need between 30 minutes and 2 hours of exercise every day, split across at least two walks. Where a dog sits on that range depends primarily on breed - not size - and age and health shape things further from there.
How much exercise does my dog need?
The Kennel Club applies one of three exercise categories to every breed in its A to Z:
- Up to 30 minutes per day
- Up to 1 hour per day
- More than 2 hours per day
Working and sporting breeds - those bred to do a job alongside people - tend to fall in the top tier. Companion and toy breeds usually sit lower. But size is a rough guide at best, and the breed tells you more than the body weight.
| Breed type | Examples | KC exercise category |
|---|---|---|
| High-energy working and sporting breeds | Border Collie, Springer Spaniel, Labrador, Husky, Weimaraner, Vizsla, German Shepherd, Golden Retriever, Dalmatian | More than 2 hours per day |
| Moderate-energy breeds | Jack Russell, Cocker Spaniel, Staffordshire Bull Terrier, Miniature Schnauzer, Greyhound, Whippet, Cavalier King Charles Spaniel, Basset Hound | Up to 1 hour per day |
| Low-energy and companion breeds | Shih Tzu, Chihuahua, Bichon Frise | Up to 30 minutes per day |
| Flat-faced breeds | French Bulldog, Pug, English Bulldog | Up to 1 hour per day - different rules apply (see below) |
Two breeds on that table are worth a closer look. Greyhounds are sprinters, not distance runners. Despite the racing reputation, adult Greyhounds - particularly ex-racers - are often among the calmest dogs in the house, and 40 to 60 minutes a day is typically enough.
Labradors sit at the other end of the perception gap. They appear easy-going, which makes it easy to assume they are getting by fine. A study of 12,314 dogs from UK owner-reported data found that only 8% of Labradors were reported to meet their Kennel Club exercise guidelines - a figure the authors highlighted given the breed’s widespread popularity. (Westgarth et al., 2017, Journal of Nutritional Science, PMC5465859)

Puppies: how much is too much?
The 5-minutes-per-month-of-age rule - so a four-month-old puppy gets no more than 20 minutes per on-lead walk, up to twice a day - is the most widely used starting point for puppy exercise in the UK. Blue Cross still references it as a practical guideline.
Worth knowing: PDSA has stated explicitly that there is no scientific evidence behind the rule, and that it is not appropriate for most puppies. It appears to have originated as informal shorthand in the working dog community rather than from any clinical research.
The principle it reflects is sound, even if the formula is uncertain. Growth plates in puppies need time to fuse before they can tolerate high-impact or prolonged forced exercise. Overloading them too early risks joint damage that may not become apparent until the dog is older.
Growth plate closure varies by breed - broadly consistent with UK vet guidance, though the exact timeline differs by individual and breed line:
- Small and medium breeds: around 12 months
- Large breeds (Labradors, Retrievers, German Shepherds): up to 18 months
- Giant breeds (Great Danes, Irish Wolfhounds): up to 24 months
Use the 5-minute rule as a starting point rather than a precise formula. Build duration gradually, watch how your dog moves during and after each walk, and avoid sustained fetch and jumping on and off furniture until the growth plates have closed. Free play in a garden - where a puppy can self-regulate - carries less risk than forced on-lead marching. For giant breed puppies, this is a conversation worth having with a vet early.
Senior dogs
Older dogs tend to do better on shorter, more frequent walks rather than fewer longer ones - it keeps them moving without the cumulative joint load of covering a lot of ground in one go. The most useful practical test: if your dog is noticeably stiffer getting up the morning after a walk than on a normal morning, that walk was probably too much. The full picture on exercising older dogs - including arthritis, the morning-after test, and when to scale back - is in the senior dog walking guide.
Flat-faced breeds
French Bulldogs, Pugs, English Bulldogs, and other brachycephalic breeds need shorter, cooler, and gentler walks than almost any other consideration suggests. Their compressed airways make panting less efficient, which means heat and exercise combine as a risk that does not apply in the same way to other dogs. The caution threshold for these breeds sits at around 15 to 20 degrees Celsius, compared to 20 to 22 degrees for most others. Full guidance on exercise limits, terrain, and heat for flat-faced breeds is in the French Bulldog walking guide. A fuller brachycephalic breeds guide is in progress.
Signs you are walking your dog too much or too little
Too much
These are things to notice, not emergencies. Look for panting that does not settle when your dog stops moving, stiffness or reluctance to rise the morning after a longer walk, slowing significantly mid-walk, sore or cracked paw pads, or reluctance to go out when they are usually keen.
Any lameness that persists more than 24 hours, or visible joint swelling, warrants a call to the vet. Dogs are generally good at masking discomfort until it has become significant.
Too little
The signs are mostly behavioural: restlessness indoors, destructive behaviour, difficulty settling in the evenings, excessive barking or whining, and slow weight gain over time. A dog getting enough exercise should be noticeably calmer at home. PDSA and Blue Cross both describe regular daily walking as the minimum baseline for any healthy adult dog, with breed and age determining how much more is needed.
Weather and seasons
Above 20 degrees Celsius, shorten walks and shift timing to early morning or late evening. Above 22 degrees, the risk becomes more serious for elderly, overweight, or flat-faced dogs. The full breakdown of temperature thresholds, the pavement test, and signs of heatstroke is in the temperature guide.
Cold is less dangerous than heat for most healthy adult dogs. Below around 7 degrees Celsius, small short-coated dogs and elderly dogs benefit from a coat and a shorter outing. Ice is the main hazard for dogs with joint problems - reduce distance and avoid slippery paths on frosty mornings. A lit collar or high-vis lead is worth having for the shorter winter days.
The Sniffout app shows breed-specific weather scoring and the safest walking window by hour of the day - useful on the days when timing matters as much as distance.
Frequently asked questions
How far can a puppy walk?
There is no fixed distance figure. The 5-minutes-per-month-of-age guideline - so around 20 minutes at four months - is a widely used starting point for on-lead walks, but PDSA notes it lacks scientific backing and should not be applied rigidly. The core principle is sound: build gradually and avoid high-impact exercise until growth plates close, which in large breeds is 14 to 18 months.
Is one walk a day enough for a dog?
For some low-energy breeds, one good walk per day is sufficient. Blue Cross considers one walk per day the minimum for any dog. For most working breeds and medium-to-large dogs, a single walk falls short - high-energy breeds like Border Collies, Spaniels, and Labradors need at least two walks with a combined total of two hours or more to meet their needs.
Can you over-exercise a dog?
Yes. Signs include panting that does not settle when your dog stops, reluctance to continue mid-walk, stiffness the morning after, and sore or cracked paw pads. For puppies, over-exercise before growth plates close carries the additional risk of lasting joint damage. Any lameness lasting more than 24 hours after a walk is worth a call to your vet.
How do I know if my dog needs more exercise?
The clearest signs are restlessness indoors, destructive behaviour, difficulty settling in the evenings, and gradual weight gain. If your dog is chewing furniture or waking the household at night, more exercise - or more varied exercise - is usually part of the answer.
How much exercise does a Labrador need?
The Kennel Club recommends more than 2 hours per day for adult Labradors. Despite being the UK’s most popular breed, only 8% of Labradors in a study of owner-reported data were meeting that guideline - a figure the researchers highlighted given how many Labs there are in the UK. Labs are calm and easy-going by nature, which makes it easy to underestimate what they actually need. Two solid walks a day, with off-lead time where possible, is the working target.
Do small dogs need less exercise?
Not always. Exercise needs are determined by breed, not body size. A Jack Russell Terrier is in the Kennel Club’s “up to 1 hour per day” tier - the same as a Greyhound, and considerably more than a Chihuahua or Bichon Frise, which the KC places in the “up to 30 minutes” category. Small does not mean low-energy. Check the Kennel Club A to Z for your specific breed.
If you have concerns about your dog’s exercise tolerance or notice any change in their willingness to walk, speak to your vet.
