A dog's power output comes from its muscle mass, which for a healthy dog is about 45% of its total body weight. This gives our 28-pound dog roughly 12.57 lbs (or 5.7 kg) of muscle.

Studies of animal muscle show that the peak power output of vertebrate muscle tissue during a short, explosive burst (like a jump or the start of a sprint) is around 100 to 200 watts per kilogram of muscle.

Now we can estimate the dog's peak power:

• Low estimate: 5.7 kg of muscle x 100 W/kg = 570 watts
• High estimate: 5.7 kg of muscle x 200 W/kg = 1140 watts

Converting these figures to horsepower (1 horsepower = 746 watts):

• Low estimate: 570 W / 746 ≈ 0.76 horsepower
• High estimate: 1140 W / 746 ≈ 1.5 horsepower

So, a small 28-pound dog might be able to generate a peak power of around 0.75 to 1.5 horsepower for a very brief moment.

So this YASA motor is somewhere between 670 and 1,340 times more powerful than the dog it's being compared to in weight. That's some jaw-dropping power output.
