The recipe for enough exercise
The famous 'five minutes per month of age' rule is a guess. What a dog needs depends on the dog, and the quality of the exercise matters more than the minutes.
Why these ingredients
Exercise is not one thing. A thirty-minute march at heel and a thirty-minute sniff in a field are the same duration and completely different work. One uses the body; the other uses the brain, and most pet dogs in developed countries are short of the second, not the first.
Puppies are where the numbers get dangerous. Growing joints, especially in large breeds, are damaged by repeated high-impact exercise — long runs, stairs, and jumping. The safe version is free play and short walks, and the amount grows as the growth plates close, not before.
The ingredients, with doses
A recipe needs amounts, not advice. Each line below is a habit with the dose that makes it work and the reason it is in the bowl.
| Ingredient | Dose | Why it is in here |
|---|---|---|
| Adult, average build | 45–60 min a day | Split into two sessions. Include at least one that is sniffing, not marching. |
| High-drive or working breeds | 90 min a day, plus a job | Huskies, border collies and pointers are not tired by a walk. They need a problem to solve. |
| Flat-faced or small breeds | 20–30 min a day | Intensity over distance. Watch breathing; heat is the enemy. |
| Puppies under 12 months | 5 min per month of age, twice a day | Plus free play. No long runs, no stairs, no jumping, no forced pace. |
| Seniors | 20–30 min, broken up | Sore joints do better with short and often than one long effort. |
Method
- Measure what you already do for a week — minutes and kind. Most people are doing more marching than they thought and less sniffing.
- Add one sniffing session a day before adding any minutes.
- For a dog that is never tired, add a job instead of distance: trick training, a scatter feed, a puzzle. Distance just builds stamina.
- For a puppy, protect the growth plates: free play, short walks, no repetitive stairs or long runs.
- In heat, move the exercise to the early morning and shorten it, especially for flat-faced and large breeds.
- Look at the dog two hours later, not during. A dog that is still wound up at night got the wrong kind of exercise.
What each part is doing
| Part | Job |
|---|---|
| Sniffing | Brain work, which is what most pet dogs are missing. |
| Two sessions | Less arousal than one long one, and better sleep. |
| A job for high-drive dogs | Stamina is not the same as satisfaction. |
| Gated puppy exercise | Protects growing joints from damage that shows up years later. |
What to watch for
- Do not run a puppy beside a bicycle or take it on a long run. Growth plates are open and the damage is permanent.
- More and more fetch trains a dog to be fitter and more obsessive, not calmer.
- Limping after exercise, reluctance to rise, or a dog that refuses walks needs a vet. Pain is the most under-diagnosed cause of 'laziness'.
