They understand us a whole lot more than we understand them.
Think about it. You can train the dog to Sit and to Stay on command word. You can say a sentence with those words in it and the dog will do it. I can even tell my dog the wrong word, when I really want them to down and I say STAY instead, and the dog goes down because of my body language or whatever. But more often than not, if I screw up my verbal commands the dogs do what I want, moreso than what I say.
We on the other hand hear the dog whimper, we ask do you want to go out, the dog gets excited, so we put him out. Doesn't want to go out, he wants his dinner! So five minutes later the dog is whimpering again, and we are like, "WHAT? I JUST LET YOU OUT!" The dog wants his food!
Or the dog comes up to our hand and starts nudging it, Oh, you want to be petted -- No, MORON, I am HUNGRY! Get off your Rusty Dusty and get me my FOOD!
After a horribly humiliating belly rub and thourough ear scratching, the dog trots off to the kitchen, and scurries around in there, pushing his bowl around and around the kitchen floor. FINALLY the owner GETS it! And feeds the dog.
