How the calculator works
Walking on flat ground costs a dog roughly 0.8 to 1.0 kcal per kilogram of body weight per kilometre. That is the range Pawdometer uses in the app and here, so the two never disagree. It comes from veterinary walking-calorie estimators and the sports-medicine literature on the cost of locomotion, which scales with body mass. The calculator shows the range and its midpoint.
The optional daily-need comparison uses the resting energy requirement, RER = 70 × (ideal weight in kg)0.75, multiplied by a life-stage factor from the WSAVA Global Nutrition Toolkit: 3.0 for puppies under four months, 2.0 from four months to adulthood, 1.6 for a neutered adult or 1.8 for an intact one, 1.2 to 1.4 for low-activity or weight-prone dogs, 2.0 for light work. Individual dogs vary by up to 50% around these figures.
One honest note: the Association for Pet Obesity Prevention's own estimator uses about 1.1 kcal/kg/km at a brisk 10-minute-per-kilometre pace. Most dog walks are far slower, with sniff stops, which is why Pawdometer stays at 0.8 to 1.0. If your dog trots the whole way, the true figure sits closer to the top of the range.
The result is a planning estimate, not a measurement, and it is never feeding advice. To see where walking fits in a weight plan, read Helping your dog lose weight by walking: an 8-week plan and How many calories does my dog need a day?.
Frequently asked questions
How many calories does a dog burn on a one-mile walk?
About 1.3 to 1.6 kcal per kilogram of body weight. A 25 kg (55 lb) dog burns roughly 32 to 40 kcal on a one-mile walk. That is one medium biscuit, which is why walking alone rarely moves weight without portion changes.
Why is the number so small?
Dogs are efficient walkers, and the cost of moving scales with weight. Walking matters for joints, muscle, behaviour and habit far more than for the calorie line. The daily-need comparison shows the walk in proportion.
Does pace change the result?
Yes, a little. Brisk walking or trotting pushes the cost toward the top of the range and beyond; the app uses the same 0.8 to 1.0 band for every walk so numbers stay comparable day to day.
Is this the same math as the Pawdometer app?
Yes. The calculator runs the exact functions ported from the app's energy model, so a walk logged in the app and the same walk typed here give the same range.
