My dogs aren't very well trained, but they do know things that I just consider manners and those have become more apparent now I have a completely untrained 3yr old who doesn't understand the things all the others do

Stopping jumping on people on command is a big one as I'm convinced I own part kangaroos.
Walking through doors, gates, in and out of crates when told to.
Walking on a leash.
Recall (No, some of mine are not good at this

).
Surprisingly only one of my dogs knows sit... I used to do conformation showing and had multiple people tell me not to teach them to sit.
