How many calories does a dog burn walking?

Most sources answer this with one number for every dog. The cost of moving depends on body size and on build, and both change the answer by more than half.

Calories burned on a 30-minute walk

At an ordinary adult walking pace of about 5 km/h, which covers 2.5 km in half an hour. Figures are energy above what the animal would have burned lying at home, and include the cost of simply being on its feet for the outing.

Body weight	Long-limbed	Average build	Short-legged	Per km, average
3 kg	11 kcal	15 kcal	19 kcal	2.03 kcal/kg
5 kg	16 kcal	22 kcal	27 kcal	1.73 kcal/kg
10 kg	26 kcal	35 kcal	44 kcal	1.40 kcal/kg
15 kg	34 kcal	46 kcal	59 kcal	1.23 kcal/kg
20 kg	42 kcal	57 kcal	71 kcal	1.13 kcal/kg
30 kg	55 kcal	75 kcal	94 kcal	1.00 kcal/kg
40 kg	67 kcal	91 kcal	115 kcal	0.91 kcal/kg
50 kg	79 kcal	107 kcal	134 kcal	0.85 kcal/kg

Why a Greyhound and a Basset are not the same animal

Two dogs of identical weight can differ by more than twofold in what a kilometre costs them. Measured trotting costs run about 0.6 kcal per kg per km for long-limbed dogs against 1.3 for short-legged ones. Long legs cover more ground per stride and per unit of muscular work; short, heavy-boned legs take many more steps to travel the same distance.

Body size pulls in the same direction. The energy to move one kilogram one metre falls as animals get larger, which is why the right-hand column above drops from 2.03 kcal per kg per km at 3 kg to 0.85 at 50 kg. A single flat figure — the 0.8 kcal/kg/km that circulates widely — is only correct for a dog of about 40 kg.

For scale: a 20 kg dog burns about 662 kcal a day just staying alive. A 30-minute walk adds roughly 57 on top — about 9% of its resting requirement. That is real, and it is also why walking alone is a slow way to shift weight.

Questions people actually ask

How many calories does a dog burn on a 30 minute walk?

▾

For an average-built dog walking at about 5 km/h, roughly 22 kcal at 5 kg, 57 kcal at 20 kg and 107 kcal at 50 kg. Build changes it substantially: a long-limbed dog burns around a third less than a short-legged dog of the same weight.

How many calories does a dog burn per kilometre?

▾

Around 1 kcal per kilogram of body weight per kilometre for dogs over 10 kg, and 1.6 to 1.9 for smaller dogs and cats. The cost per kilogram rises as animals get smaller, so a flat figure understates a toy breed by more than half.

Do heavier dogs burn more calories walking?

▾

Yes in total, but less per kilogram. A 50 kg dog burns about five times what a 5 kg dog burns on the same walk, not ten times, because the cost of moving each kilogram falls as body size rises.

Does breed affect how many calories a dog burns walking?

▾

More than most people expect. Measured trotting costs run about 0.6 kcal per kg per km for long-limbed dogs against 1.3 for short-legged ones — over twice the difference — at comparable body weight. Greyhounds and whippets travel cheaply; dachshunds, bassets and corgis do not.

Is walking enough to make my dog lose weight?

▾

On its own, rarely. In a plan built around the safe rate of loss, walking supplies roughly a third of the weekly calorie deficit and the food adjustment supplies the rest. Walking is what protects muscle and joints while the diet does the heavier lifting.

How many calories does an hour of walking burn for a dog?

▾

Roughly double the 30-minute figure at the same pace, so about 114 kcal for a 20 kg dog and 214 kcal for a 50 kg dog. Length matters more than pace for a walking gait, because most of the cost is proportional to distance covered.

Work it out for your own dog

The planner applies all of the above to your dog’s actual weight, breed and age, then tells you the distance, the calorie figure and how long the goal will take. Build a plan, or read how much weight walking can actually take off.
