My opinion..
For MOST pet dogs no you don’t because most pet dogs are bred with a submissive, ‘people pleaser’ temperament because that is the temperament that fits best for a family pet.
While I think all dogs will benefit from being taught polite behaviour and having that enforced I don’t believe that most dogs need permission to get on the sofa, sit and wait before eating, always walk behind you etc etc.
For most dogs, behaviour problems are the result of anxiety and not the result of an attempt to overthrow you and assert dominance and ‘be the leader’.
That said, I absolutely do believe that some dogs have very controlling, overbearing personalities and do want to be the boss and will persistently ‘test’ you and challenge any behaviour from you they perceive to be unacceptable/rude.
Those dogs absolutely do need firm handling - no sofa access unless invited and must get off immediately if requested, must enter after you, must sit and wait for food etc.
I don’t think it is ‘pack/alpha’ behaviour though, I just think that like how some people are shy, some middle ground and some of us are quite overbearing and keen to be ‘the leader’, dogs are just the same.
Most are shy or middle ground.
Some are not...
