There is no single number. What a dog needs depends on age, breed, health and — crucially — what kind of exercise it is.
Rough guidelines for adults
- Low-energy breeds and brachycephalics — Bulldogs, Pugs, many giant breeds, Basset Hounds: 30 minutes a day, split, in cool conditions
- Average pet dogs — most Retrievers, Spaniels, mixed breeds: 60 minutes
- High-energy working breeds — Collies, Malinois, Vizslas, Huskies, working-line Spaniels: 90 minutes to 2 hours, with substantial mental work alongside
- Sighthounds — a genuine curiosity: enormous sprinting capacity, very low endurance needs. A Greyhound is typically happy with two or three 20-minute walks and a chance to sprint
These are starting points. Fitness, weather, age and individual temperament shift them considerably.
Puppies: the five-minute rule
A widely used guideline: five minutes of formal exercise per month of age, once or twice a day.
- 3 months: 15 minutes, once or twice
- 6 months: 30 minutes
- 9 months: 45 minutes
The reasoning is growth plates — areas of developing cartilage at the ends of long bones, which do not close until somewhere between about 8 and 18 months depending on size. Repeated high-impact loading before closure is associated with joint problems later.
The rule is a guideline, not physiology. It applies to formal, sustained, repetitive exercise — a road walk, a jog, a long hike. It does not mean a puppy must sit still for the rest of the day. Free play in a garden, where a puppy self-regulates and rests when tired, is different and generally fine.
What to avoid in growing dogs, particularly large breeds:
- Long repetitive road walks
- Jogging or cycling alongside
- Repeated stair climbing
- Jumping down from heights, including out of cars
- Hard ball chasing with sharp turns and skids
- Agility jumping before growth plates close
Seniors
Older dogs still need exercise — muscle protects arthritic joints, and mobility is use-it-or-lose-it.
- Little and often. Three or four twenty-minute walks beat one long one
- Consistency matters more than volume. A sedentary week and then a three-hour hike at the weekend is the worst pattern for an arthritic dog
- Soft, even ground where possible
- Swimming and hydrotherapy are excellent — non-weight-bearing while building muscle
- Watch for stiffness the following day, which means it was too much
Why more is not always better
This is the part people get wrong most often.
Ball chasing. Repeated high-speed chasing with sudden stops and skids causes real orthopaedic wear, and it produces a state of high arousal that is self-reinforcing. A dog who has chased a ball for forty minutes is not calm; they are flooded with adrenaline and often unable to settle afterwards. Some dogs develop a genuine compulsion around it.
Occasional fetch is fine. Forty minutes of it, daily, is not the exercise most dogs need.
Building an athlete. A dog conditioned to run for two hours a day needs two hours a day. If your circumstances change, you have a problem you created.
Over-arousal. Many dogs described as needing “more exercise” actually need more rest and more mental work. A dog who cannot settle, who is destructive and vocal, may be chronically over-stimulated and under-slept rather than under-exercised.
Sleep is the missing variable
Adult dogs need roughly 12 to 14 hours of sleep a day; puppies 18 to 20; seniors somewhere in between and more fragmented.
An under-slept dog is irritable, less able to learn, more reactive and more likely to mouth and nip — exactly as an over-tired toddler is.
In busy households, many dogs simply never get an uninterrupted block of rest. Enforcing naps, with a crate or a quiet room, is one of the most effective and least used interventions for “hyperactive” dogs.
Mental work counts, and counts heavily
Twenty minutes of scent work or problem solving is more tiring than twenty minutes of walking.
- Sniffing walks — let them sniff, do not march
- Snuffle mats and scatter feeding
- Puzzle feeders
- Ten minutes of training
- A long-lasting chew
For a working breed in a pet home, this is not an optional extra. It is the part of their needs that walking does not touch.
Signs of under-exercise
- Destructive behaviour
- Restlessness, pacing, inability to settle
- Weight gain
- Excessive barking
- Attention-seeking behaviours
- Digging
- Waking early and being immediately demanding
Signs of over-exercise
- Lagging behind or lying down on walks
- Stiffness or limping, especially the next day
- Excessive panting and slow recovery afterwards
- Sore or worn pads
- Reluctance to go out
- Muscle tremors
- A dog who is wired rather than tired afterwards
Conditions that change the answer
Brachycephalic breeds overheat easily and have compromised airways. Short walks, cool parts of the day, and a harness never a collar.
Arthritis — consistent, moderate, soft surfaces.
Heart disease — exercise to tolerance, guided by your vet.
Post-surgery — strictly as directed, and use mental enrichment to fill the gap.
Hot weather — early and late, the pavement test, and skip it entirely on the worst days.
A reasonable daily shape
For an average adult dog:
- Morning: 30 minutes, including proper sniffing time
- Midday: a short toilet break and a puzzle feeder
- Afternoon or evening: 30 minutes, varied route
- Through the day: a chew, some training, and several hours of genuinely undisturbed sleep
Two of those four are not walks — and for most dogs, that balance is closer to what they actually need than another lap of the park.
