"Five Minutes Per Month of Age": Where the Puppy Exercise Rule Came From
The Kennel Club gives the five-minute rule; a vet charity says no science backs it. What the one large puppy study found about stairs and off-lead play.

The UK’s Kennel Club tells owners that “a good rule of thumb is a ratio of five minutes of formal exercise per month of age (up to twice a day) until the puppy is fully grown” (The Kennel Club). The UK vet charity PDSA says “there’s no scientific evidence behind this rule” (PDSA).
While both bodies want to protect growing joints, only one large study has looked at puppy exercise and hip problems. It didn’t measure minutes. This page explains what it found, and what the rule can and can’t do.
1. Where the rule comes from
We couldn’t trace it. We found no study that tested five minutes per month of age, or any other time limit. Neither the Kennel Club nor PDSA cites a source.
What the Kennel Club means by “formal” exercise. It separates walks from play. “For puppies, informal natural play is one of the most important forms of exercises”, and “Puppies tend to self-limit play”. The five-minute rule applies to walks.
What PDSA says instead. It says the rule “might work for some” but is “not appropriate for most puppies.” It advises owners to consider a puppy’s size, breed and lifestyle.
Our note: We found no origin for the rule, and no evidence for any time guide.
2. The one large study
What was studied. Norwegian researchers followed 501 puppies of four large breeds from birth to their hip X-rays at 12 or 18 months: Newfoundlands, Labradors, Leonbergers and Irish Wolfhounds. Owners reported how the puppies were housed and exercised (Krontveit et al., American Journal of Veterinary Research 2012, abstract).
Stairs. “Puppies walking on stairs from birth to 3 months of age had an increased risk of developing HD.” HD is hip dysplasia, a malformation of the hip joint.
Off-lead play. “off-leash exercise from birth to 3 months of age” was linked to a lower risk. So were being born in spring or summer, and being born on a farm.
The authors’ advice. They concluded that puppies of 3 months or younger “should not be allowed access to stairs, but should be allowed outdoor exercise on soft ground in moderately rough terrain”.
What it doesn’t show. The study was in four large and giant breeds. It found associations, from owner questionnaires, not cause and effect. It looked at the first 3 months only, and didn’t measure walk length.
Our note: The study linked off-lead exercise on soft ground in the first 3 months to lower risk. That sits awkwardly with strict limits on exercise.

3. What the advice agrees on
Stairs. The Kennel Club advises puppies to “Avoid using the stairs until at least 12 weeks old, but this may be longer for some larger breeds”. That matches the Norwegian study’s 3-month window.
High-impact exercise. The Kennel Club advises avoiding “jumping from heights or being taught to jump” and “sharp sudden turns, such as chasing a ball.” PDSA says to “discourage them from jumping up and skidding”. We didn’t find studies testing these points.
Weight. The Kennel Club says “overweight puppies have an increased risk of joint disease as they mature”.
Growing time. PDSA notes that larger breeds “can take as long as 18 months to 2 years to reach full size”.
Our note: The advice on jumping and sharp turns comes from charity and breed-body pages, not studies.
4. What to ask your vet
- How long will my puppy keep growing?
- Is my puppy’s breed at higher risk of hip or elbow problems?
- How much walking and play suits my puppy now?
- What signs would mean my puppy is doing too much?
Our note: These questions are ours. If your puppy limps or seems stiff, see your vet.

5. What we could not verify
| Commonly said | What we found |
|---|---|
| “Five minutes per month of age” | No study found. The Kennel Club gives it as a rule of thumb. PDSA says no science backs it. |
| “Too much exercise causes hip dysplasia” | Not shown for walk length. One study linked stairs in the first 3 months to higher risk, and off-lead play to lower risk. |
| “Puppies shouldn’t use stairs” | Supported by one large study in four large breeds, for the first 3 months. |
| “Free play is safer than walks” | Partly supported. Off-lead exercise in the first 3 months was linked to lower risk in one study. It wasn’t compared with lead walks. |
| “Small breeds need the same limits” | Not tested. The study covered four large breeds. |
