My only issue with the article is that I suspect that many people see "parent" and think "baby", "toddler", or "child" (though I don't think this is what the author intended).
A dog is not a child. It's not a wolf, either (as the article points out, there are many, many generations of natural and human-guided selection separating the wolf from the dog). It's a dog. There's a tendency to think of our dogs as "fur-children" or "little people in fur coats", and that kind of thinking just isn't fair to the dog - who is, at the end of the day, a dog, and possessed of a dog's brain and a dog's way of thinking.
I think the thing to emphasize in this article is that you should aim to be a good
dog parent - that is, a dog who is a parent, not a human with a dog-child. Be firm but fair. Set rules and boundaries, and stick to them. Be confident and a good leader. Don't coddle or baby (except in cases of genuine illness... and in old age, coddle as much as you want, the dear dog's earned it). (Oh dear, I think that's how my own parents were!

And I'm grateful for it.)
