Raising a dog or a kid?

I have this argument with people a lot , I'm curious of your opinions. I work in child care with ages 6 months to 12 years old for 5 years. I worked with all ages of children from 12 to 26 years old and adults up to seniors for 3 years. I've been rescuing and rehabilitating dogs from pups to seniors for 6 years.
I believe raising a puppy or training a dog with someone can show you a lot about your partners compatibility to raise a child together. Agreeing and disagreeing on certain aspects of how a dog or puppy should be raised or trained has caused conflict... deep conflicts with relationships of mine ( especially since I rescue only). I can be in baby fever for months till the moment I see how someone treats a dog or another animal. I've made the argument that we would fight a lot since we can't agree on training and raising a dog a particular way, and its turned me off to continuing the idea of a family. Some of my partners argue that a dog is nothing like a kid, I've heard both sides from people WITH kids , that raising a kid is harder or I wish I got dog /animal first to see how we worked together.
Do you agree or disagree, and why

Raising a dog is no where near the level of raising a kid. I suppose you could use it as an indicator of how they handle the stressors of crate training or chewing up the walls, but kids are 1000% harder. If they can't handle a dog then they can't handle a kid. But being able to take care of a dog does not indicate you can take care of a kid. I have raised 5 dogs in my life, 4 cats, and 4 guinea pigs. My 8 month old is worse than all of them combined and nothing could have prepared me for it.

Having a dog teach you how to be an human. I mean, animals are more unprotected than kids (in legal way and people who fight for them). I know that this isn't and answer but I feel that i have to tell this ):
