Some of the basic ones that most people think of are "sit," "stay," and even some target training, which can be really useful. Having them respond to those basic commands can be very helpful. For example, if you can teach your pet to sit and stay on command or go to a particular location and sit or stay, you can prevent things like your dog slipping out the front door when it's open, which can be really dangerous in some situations. So I think the elementary stuff is essential.

Obedience training should start as soon as possible. The sooner you can start, the better your success, especially in a younger puppy. When you start at a young age, you will have more success with basic obedience, particularly regarding socialization, which is often not focused on enough in young dogs.
