How this instrument works
This calculator estimates calories burned during a dog walk from two numbers: body weight in kilograms and how long the walk lasted in minutes. It uses the MET (metabolic equivalent of task) system, a standard way exercise scientists express how energy-intensive an activity is relative to sitting still, which is defined as 1 MET.
Dog walking has its own dedicated MET value of 3.0 in the Compendium of Physical Activities, the widely used reference researchers maintain for coding energy costs of hundreds of specific activities. That 3.0 figure sits below the MET value typically assigned to a purposeful, brisk walk at a steady pace — dog walking's stop-and-start rhythm, with pauses to sniff, sniff some more, and occasionally double back, tends to burn calories a bit more slowly than walking with a fixed destination in mind.
This is a light fitness and wellness estimate, not a medical calculation — useful for a rough sense of how a daily dog walk adds up, not for tracking a strict calorie budget. Actual burn varies with terrain, pace, how many times the dog stops, and individual differences in metabolism that a single MET-based formula can't capture.

Worked example — 70 kg, 30-minute walk
A 70 kg person walking their dog for 30 minutes: 3.0 × 3.5 × 70 ÷ 200 × 30 = 110.25 kcal.
A heavier 90 kg person on a longer 45-minute walk burns more: 3.0 × 3.5 × 90 ÷ 200 × 45 ≈ 212.6 kcal. A lighter 55 kg person on a shorter 20-minute walk burns less: 3.0 × 3.5 × 55 ÷ 200 × 20 = 57.75 kcal — the same formula scaling with both body weight and time.
Questions
Why does dog walking have its own MET value instead of using regular walking?
The Compendium of Physical Activities assigns MET values based on how activities are actually performed, and dog walking has a distinct rhythm from a purposeful walk — frequent stops to sniff, investigate, and let the dog set part of the pace, rather than a steady stride toward a destination. That's reflected in dog walking's own 3.0 MET code, which sits lower than the value typically assigned to a brisk, purposeful walk of the same duration.
What is a MET, exactly?
MET stands for metabolic equivalent of task, a standard unit exercise scientists use to express how energy-intensive an activity is relative to resting quietly, which is defined as exactly 1 MET. An activity at 3 METs burns roughly three times the energy of sitting still over the same span of time. The Compendium of Physical Activities catalogs MET values for hundreds of specific activities, from sleeping to competitive running, so researchers and calculators can estimate energy cost from an activity's code rather than measuring it directly.
Does a faster-paced dog walk burn more calories than this estimate?
Likely yes, though this calculator doesn't adjust for pace — it applies a single 3.0 MET value regardless of how quickly the walk moves. A faster, more purposeful dog walk with fewer stops would sit closer to a generic brisk-walking MET value, which is higher than 3.0, so this calculator's estimate is best read as a reasonable baseline for a typical, sniff-heavy dog walk rather than a fast-paced one.
Is this calculation precise enough to plan a diet around?
Not precisely — treat it as a ballpark estimate. MET-based formulas are population averages and don't account for individual differences in metabolism, walking terrain, how many times the dog stops, or incline. It's a reasonable way to get a general sense of how a daily walk adds up, not a substitute for more precise tracking methods if exact numbers matter to you.
Does the dog's size or breed change the calorie estimate?
No — this calculator only accounts for the human walker's weight and the walk's duration, using dog walking's standard MET value. The dog's size, breed, or energy level isn't part of the Compendium of Physical Activities' MET coding for this activity, though in practice a more energetic dog might indirectly change the human's pace and thus the real-world calorie burn.
Where does the 3.0 MET value for dog walking come from?
It's from the 2011 update to the Compendium of Physical Activities (Ainsworth et al., Medicine & Science in Sports & Exercise), the standard reference exercise scientists and calculators use for coding the energy cost of specific activities. Dog walking is listed with its own code and 3.0 MET value, separate from other walking-related entries in the same compendium.
