Oh you are absolutely right, no question. Having been ruled by several in my life I know their history well.
But ultimately all they did was selective breeding. Humans have done the very same thing, as without that ‘race’ wouldn’t exist. We’d all be light brown with dark hair. Hubie just refined the process.
You’re not suggesting different human races are the result of selective breeding, are you?
That would be the effects of natural selection in different climates and locations.
And the first dog I grew up with when I was small was a lovely, infinitely patient and attention-loving lady basset.
