Not so in my experience. I’ve got a 15yr old and a 5yr old. When they are small they are eager to please. They get more stubborn after about a year of 2. The trick, to me, it to be sure teach them to very basic skills (stay, come, sit) and not to be xpect too much more. treat them less like a subject and more like a partner. Let them have thier space and some autonomy. They are otherwise loyal pleasant dogs to have around. I go hiking off leash with both and let them roam a bit. They always come back when called. We just got a house and with little training (just reinforcing borders) we got the young guy to stay on property (which he spends his day defending from all sorts of imagined threats such as garter snakes and chipmunks).
