The article says "elephant feces have a volume of 20 liters, nearly a thousand times more than a dog's, at 10 milliliters." Is 10K nearly 20K?

Regardless, modern dog breeds vary in size wildly, and I'm curious how they standardize the average fecal volume across the sizes. My dogs are most certainly not expelling just 10 milliliters... I can't imagine that number is even accurate for small dogs.
