So being a work slave is in their DNA is your argument. If only capitalists could tap into this power. Like I don't know how you think they could actually be bred with the literal desire to be sled dogs. Bred for the ability to do it well? Sure. Bred to be overly loyal to a species that domesticated them and so are noticeably subservient? Sure. Bred for a specific occupation? Nah.
Like I said, physically I don't disagree, but to say it's literally in their DNA that they want to pull over-weighted sleds is silly.
And I have trouble accepting that them being bred to be slaves means they actually want to. Like I said, training and obligation.
Have you ever actually spent time around "working breed" dogs? Seen how they act when they get the opportunities to burn off a ton of energy vs when they don't?
