Enter a horsepower value and pick a dog breed to see how many dogs it would take to match that output — or flip it around and turn a pack of dogs back into HP.

Formula
HP → Dogs:
Dogs = HP ÷ HPdog
where HPdog is the sustained power output of one dog of the selected breed.
Dogs → HP:
HP = N × HPdog
where N is the number of dogs.
Unit conversions:
1 HP = 745.7 W = 0.7457 kW
Interpretation
The result tells you how many dogs, pulling or working in parallel, would produce the same sustained power as the engine or motor you entered. It is a novelty comparison, not a biomechanical claim — real dogs do not team up with perfect efficiency. Use the breed selection to get a rough scale: a Labrador pulls roughly 0.1 HP, a trained sled dog closer to 0.22 HP.
- Under 20 dogs: manageable pack, comparable to a real sled team.
- 20–100 dogs: large kennel or racing operation.
- 100–1,000 dogs: impractical; well beyond any working team.
- 1,000+ dogs: pure thought experiment — a mid-range car easily lands here with small breeds.
Typical HP Per Dog by Breed
| Breed | Size | Sustained HP | Watts |
|---|---|---|---|
| Chihuahua | Tiny | 0.03 | ~22 W |
| Beagle | Small | 0.06 | ~45 W |
| Labrador | Medium | 0.10 | ~75 W |
| German Shepherd | Large | 0.15 | ~112 W |
| Siberian Husky | Sled-capable | 0.22 | ~164 W |
| Alaskan Malamute | Heavy working | 0.28 | ~209 W |
| "Average dog" | Mixed reference | 0.143 (1/7) | ~107 W |
FAQ
Why is one horsepower not equal to one dog?
The horsepower unit was calibrated to a draft horse, not a dog. A working dog produces roughly one-seventh to one-tenth of a horse's sustained output, which is why it takes several dogs to equal a single HP.
Which breed setting should I use if I don't know?
Use Labrador (0.10 HP) as a general medium-dog default, or "Average dog" (0.143 HP) if you want the commonly cited 1/7-HP rule of thumb.
Can dogs really produce peak power much higher than these numbers?
Yes — a dog can briefly spike well above its sustained output during a sprint or hard pull. The values here reflect sustained working power, which is what matters when comparing to an engine's rated HP.
What's the difference between mechanical HP, metric HP, and kW in the input?
Mechanical HP (≈745.7 W) is the US standard. Metric HP or PS (≈735.5 W) is common in European specs and is about 1.4% smaller. Kilowatts are the SI unit; 1 kW ≈ 1.341 HP.
