Walking on flat ground costs a dog roughly 0.8 to 1.0 kcal per kilogram of body weight per kilometre, or about 1.1 at a brisk pace. A 25 kg (55 lb) dog therefore burns around 60 to 75 kcal on a 3 km (1.9 mile) walk, roughly one and a half medium dog biscuits. A 10 kg dog burns about 25 to 30 kcal on the same walk. The number is small on purpose: dogs are efficient walkers, and the walk's value is in muscle, joints, behaviour and habit far more than in the calorie line.
The formula and where it comes from
The Association for Pet Obesity Prevention's walking-calorie estimator uses about 1.1 kcal per kg per km, derived from the 2014 AAHA weight management guidelines, at a reference pace of roughly 10 minutes per kilometre. PetMD's widely quoted figure of 0.8 kcal per pound per mile is the same number in imperial units. The underlying science is the cost-of-transport work of Taylor, Heglund and Maloiy: the energy an animal spends to move a kilogram one kilometre falls as the animal gets bigger, which is why small dogs sit at the top of the range and large dogs at the bottom.
Pawdometer uses 0.8 to 1.0 rather than 1.1 because the reference pace behind 1.1 is a brisk one, and VCA's clinical guidance notes that most people walk their dogs at about 25 minutes per mile including sniff stops, far below it. Using the lower band keeps the app honest for the walks people actually take; if your dog trots the whole way, the truth is at the top of the range and the calculator shows you the brisk figure too.
Worked examples by weight and distance
All values are from the 0.8 to 1.0 kcal/kg/km range used by the app and the walk calorie calculator.
| Dog's weight | 1 km (0.6 mi) | 2 km (1.2 mi) | 3 km (1.9 mi) | 5 km (3.1 mi) | Per mile |
|---|---|---|---|---|---|
| 5 kg (11 lb) | 4–5 kcal | 8–10 kcal | 12–15 kcal | 20–25 kcal | 6–8 kcal |
| 10 kg (22 lb) | 8–10 kcal | 16–20 kcal | 24–30 kcal | 40–50 kcal | 13–16 kcal |
| 15 kg (33 lb) | 12–15 kcal | 24–30 kcal | 36–45 kcal | 60–75 kcal | 19–24 kcal |
| 25 kg (55 lb) | 20–25 kcal | 40–50 kcal | 60–75 kcal | 100–125 kcal | 32–40 kcal |
| 35 kg (77 lb) | 28–35 kcal | 56–70 kcal | 84–105 kcal | 140–175 kcal | 45–56 kcal |
| 45 kg (99 lb) | 36–45 kcal | 72–90 kcal | 108–135 kcal | 180–225 kcal | 58–72 kcal |
Read across the row for your dog's weight. A 15 kg (33 lb) Cocker Spaniel on a 2 km walk: 24 to 30 kcal. A 45 kg (99 lb) Bernese on a 5 km walk: 180 to 225 kcal, which is still less than a cup of most dry foods.
Against the daily need: RER and MER
To see what a walk means, put it next to what the dog needs in a day. The resting energy requirement is RER = 70 × (ideal weight in kg)0.75; the maintenance requirement multiplies that by a life-stage factor from the WSAVA tables (1.6 for a typical neutered adult, 1.8 intact, 1.2 to 1.4 for weight-prone dogs, 2 to 3 for puppies). For a 25 kg neutered adult that is an RER of about 783 kcal and a maintenance need of about 1,250 kcal a day. The 3 km walk above is 5 to 6 percent of it.
That is the honest proportion: a good daily walk is a real contribution, and it is a small one. The full formula with worked examples is in How many calories does my dog need a day?.
Pace, hills and sniff stops
- Pace. The cost per kilometre rises modestly with speed at a walk and jumps at a trot. Brisk walking sits around 1.1 kcal/kg/km; a sustained trot is higher still.
- Hills. Climbing adds real cost; descending adds little and loads the front legs. Flat-ground formulas under-count hilly walks.
- Sniff stops. Standing still burns almost nothing extra, which is why a sniffy 30-minute walk covers less ground and burns fewer calories than a purposeful one. It is still a good walk; it is just a different kind of good. Pawdometer detects stops of 30 seconds or more and excludes them from pace, so the distance and moving time stay honest.
One treat undoes it
This is the part that changes behaviour. Typical values: a medium dog biscuit around 40 kcal, a dental chew 70 to 100, a tablespoon of peanut butter about 95, a slice of cheese about 100, a hot dog around 150. A 25 kg dog's entire 3 km walk is one slice of cheese. Nobody should stop rewarding their dog; but the maths says the reward should be a small piece of the dinner ration, not a bonus on top of it.
What walking does that calories don't show
If the calorie count were the whole story, walking would be a rounding error and nobody would bother. It is not the whole story. Regular walking keeps lean muscle on a dog who is losing weight, so the loss is fat rather than strength. It keeps joints moving, which is the best non-drug protection against the stiffness that comes with age and extra weight. It lowers arousal and reactivity at home. And it builds the daily routine that makes portion control stick, because a dog with a schedule is a dog whose owner is paying attention. The weight-loss plan in Helping your dog lose weight by walking: an 8-week plan is built on exactly that division of labour: walking for the body, portions for the scale.
Estimate, not measurement
Everything on this page is an estimate from formulas, and the same is true of any app or collar that shows dog calories. There is no consumer device that measures a dog's energy expenditure; the only measurement in the chain is the distance, if it comes from GPS. Pawdometer labels the calories "(est.)" for that reason, shows them as a range, and uses the walk's GPS distance and your dog's logged weight on the day rather than a typed guess. It never gives feeding advice; that conversation belongs to you and your vet.
Pawdometer. Pawdometer shows every walk's calories as a range against your dog's daily need, labeled as an estimate, and never tells you what to feed.

Frequently asked questions
How many calories does a 30-minute walk burn for a dog?
It depends on distance, not minutes. At a typical 25 minutes per mile, 30 minutes is about 1.2 miles (2 km): roughly 16 to 20 kcal for a 10 kg dog, 40 to 50 kcal for a 25 kg dog. At a brisk 15 minutes per mile the same half hour covers 2 miles and burns nearly twice that.
Is walking enough for a dog to lose weight?
Rarely on its own. A daily 2 km walk is about 3 to 5 percent of a typical dog's energy need. Walking preserves muscle, protects joints and makes the habit, but portion size does most of the work. See the weight-loss walking plan for how the two fit together.
Do dogs burn more calories than humans walking?
Per kilogram, small dogs burn more than people and large dogs about the same or less. In absolute terms a 25 kg dog burns far less than a 75 kg person over the same mile, roughly a third.
Why does Pawdometer show a range?
Because the true cost depends on pace, terrain and the individual dog, and a single number would be false precision. The app shows 0.8 to 1.0 kcal per kg per km as a range and uses the midpoint for totals.
