The rule vets and breeders use is about five minutes of leash walking per month of age, up to twice a day: 15 minutes at three months, 20 at four, 30 at six. Treat it as a ceiling, not a target. Puppies need lots of movement, but most of it should be free play, sniffing and short training sessions on soft ground, because their growth plates stay open until 12 to 18 months and repetitive impact on them is what causes trouble later.
The 5-minute rule and its limits
The rule is a rule of thumb, not a study. It exists because the alternative, walking a puppy like a small adult, is how people end up with a limping five-month-old. Both the AKC and Rover give it as the starting point, with the same caveat: it covers structured leash walks, the kind where the puppy trots steadily beside you on pavement. It does not cap sniffing around the garden, playing with a soft toy, or the wandering pace of a puppy who stops every four feet.
Two other limits matter more than the clock. First, the puppy's own signals: sitting down, lagging, lying flat, or the frantic overtired zoomies all mean the walk is over. Second, the surface: grass and dirt forgive; concrete does not.
Month-by-month chart
| Age | Leash walk per outing | Outings per day | Rough distance | What to focus on |
|---|---|---|---|---|
| 8 to 12 weeks | 5 to 10 minutes, mostly carried or in your own space | Many short potty trips | A few hundred feet | Handling, house training, the world going by |
| 3 months | About 15 minutes | 1 to 2 | Up to about half a mile | Leash comfort, sniff time, meeting calm dogs |
| 4 months | About 20 minutes | 2 | Half a mile to three quarters | Walking past distractions, recall games |
| 5 months | About 25 minutes | 2 | Up to about a mile | Loose-leash walking; teething means chewy walks |
| 6 months | About 30 minutes | 2 | About a mile | Adolescence begins; consistency over distance |
| 9 months | About 45 minutes | 2 | 1 to 1.5 miles | Still no jogging; longer sniff walks |
| 12 months | About 60 minutes | 2 | 1.5 to 2 miles | Small and medium breeds approach adult routines |
| 12 to 18+ months | Adult routine, introduced gradually | 2 to 3 | See adult bands | Large and giant breeds are still growing; keep it gentle until the vet clears running |
Distances assume a puppy's real pace, which is slow and interrupted. A GPS track of a 20-minute puppy walk usually shows a lot less ground than people expect, and a lot of stops. That is normal and good.
When can a puppy go outside?
Puppies get their core vaccines in a series that usually finishes at 14 to 16 weeks, and the last dose needs a week or two to take full effect. Until then, most vets recommend keeping paws off ground that unknown dogs use: public parks, pavements outside busy dog areas, pet-store floors. Your own garden, friends' vaccinated dogs, and carried outings to see the world are fine and important for socialisation.
Your vet gives the exact all-clear date. Once you have it, the five-minute rule takes over.
Growth plates: why more is not better
A puppy's long bones grow from soft cartilage plates near each end. They harden into bone at about 12 months in small breeds and 18 months or later in large and giant breeds. Until they close, they are the weakest part of the skeleton, and repetitive impact, jumping down from heights, stairs and long forced marches are the things orthopaedic vets warn about. The AKC's guidance is blunt: no jogging with a puppy before the growth plates close, and for big dogs that means well past their first birthday.
Weight matters here too. A chubby puppy loads its joints on every step, and puppies grow fast enough that a monthly weigh-in is worth doing. When puppies of different sizes finish growing, and how to weigh them, is in When do puppies stop growing?.
Sniffing counts more than distance
Ten minutes of sniffing tires a puppy's brain in a way ten minutes of marching does not. Let the walk be slow. A puppy who stops to investigate every bush is doing exactly what the walk is for. If you measure these walks with GPS you will see a short distance, a long time and many stops, and that is a successful puppy walk, not a failed adult one. Short legs also mean a lot of paw steps for that short distance; the paw steps calculator shows how many for your puppy's current height.
Large-breed puppies
A six-month-old Labrador, Shepherd or Bernese looks like an adult and moves like a puppy. Their growth plates close last, their joints carry the most weight, and hip and elbow problems in these breeds are partly a story about early exercise. Keep them at the bottom of the chart, stay on soft ground, skip the stairs and the fetch marathons, and let the vet decide when running starts. Their adult routine, when it comes, will be one of the biggest in How far should you walk your dog? Miles per day by size.
When to start tracking
From the first proper walk. Not to push distance, but to see the pattern: a puppy's walks should get slightly longer each month and stay short within each day. A measured record also gives you something concrete to show the vet if anything looks off, and it means the first "First Walk" award is a real memory rather than a guess.

Frequently asked questions
How far can a 3-month-old puppy walk?
About 15 minutes of leash walking at a time, which is roughly half a mile at puppy pace, up to twice a day. Sniffing, play and short training sessions fill the rest of their exercise need without loading the joints.
How long can a 4-month-old puppy walk?
Around 20 minutes per walk, twice a day. If the puppy flops down or lags, the walk was long enough already; carry them home rather than coaxing.
When can my puppy go for walks outside?
On your own property or in carried-only outings from the start; on public ground once the vaccine series is complete, usually at 14 to 16 weeks, plus the one to two weeks the final dose needs to take effect. Ask your vet for the exact date.
Can I over-exercise my puppy?
Yes, and it is the most common puppy-walking mistake. Growth plates stay open until 12 to 18 months (later in giant breeds), and repetitive impact on them is linked to joint problems later. Keep walks short, avoid jogging and stairs, and let the puppy set the pace.
Does a tired puppy mean a well-exercised puppy?
Not necessarily. Puppies get overtired and wired, which looks like needing more exercise and is the opposite. Most puppies need 18 to 20 hours of sleep a day; a nap fixes more zoomies than a walk does.
