Short answer: no. You do not need to act like a pack leader or dominate your dog. Training works better with clear communication and rewards.
What VCA says
VCA says much of our dog pack and alpha talk comes from research on wolves, and that recent research shows wolves do not live in packs run by an aggressive leader. It says the alpha male and female are in charge only because they are the parents. It also says many behaviors people call dominant are usually something else, and that dogs who show aggression are often wrongly labeled alpha.
What Tufts says
Tufts says the dominance idea came from studies of captive wolves that have since been debunked. It says dogs live in loose, flexible social groups and are attached to us.
What to do instead
Teach what you want, reward it, and manage the setup. See management first and sleeping on the bed.

Frequently asked questions
Is the alpha theory true?
It came from old studies of captive wolves and has been corrected by newer research. Dogs live in flexible social groups.
What should I do instead of dominating?
Teach what you want with clear cues and rewards, and manage the setup so the right choice is easy.
Does letting my dog sleep on the bed cause problems?
No rule says so. What matters is the household routine you can keep up calmly.
Does my dog see me as the pack leader?
Dogs repeat what works. If pushing or barking earns attention, those habits grow. Reward the calm choices instead.
