Ooh, I don’t know about dogs having been made stupid.
They come from the womb, equipped to do the things they need to do, unlike humans.
For example, we just got a chihuahua puppy 3 weeks ago, and it was 6 weeks old. After about a week, it was doing things that human babies can’t do. It eats and drinks on its own (after the food and water are served). It waits to go outside to do its #1 and #2. It runs and plays without supervision. It had a hard time learning how to climb stairs, but, just before it turned 2 months old, it had figured it out on its own. I observed how he was frustrated about not being able to climb even the first step. Then, the puppy took 4 steps back, and with a running start, it went up the stairs with no problem at all. Nobody taught him how to step back and take that running start. We bought him a little kennel 3 days and put a kennel-sized pillow inside, and the puppy figured out that, that was his bed, and he’s been sleeping there ever since. He wants to be held all the time, but, when we tell him “kennel” he knows what we mean and immediately goes to it.
So, what human baby 2 years old can do all of that on his/her own? Heck, even 3-year old kids have a hard time with some of those things that a puppy comes naturally equipped to do.
