Dogs communicate through body language and energy. The leader of the pack is always filled with a calm and assertive energy. Pack leaders never project nervousness, panic, or tension. In other words, the pack leader is a calm and assertive presence that gives balance to the pack. He controls everything and leaves nothing open to debate or discussion. He will also not say thank you for waiting or following.
The gender of the pack leader is irrelevant and not an issue. Both males and females can be equal pack leaders.
People make the mistake by treating dogs like humans. Every species has its own psychology if we understand its psychology we can control the behavior because we know how to relate to them.
Newborn puppies have to find a place or status within the pack. They do not get a name like we do, because personality is something humans create and only exists in our world. In the animal world there are two roles - the leader and the follower.
