@frostfire,
Typically - Being a 'pack-member' (Dogs).
Alphas' lead, protect and preserve - Betas' support.
There are no omegas.
You are applying a 'human-construct' to a pack-mentality (anthromorphisising).
Does not apply.
My malamute/labrador is a dominant alpha, by nature and by litter - But, and BOY! what a backbreaking challenge, knows he need not take alpha-role lest I perish.
Alphas' are equal members of a pack (Not superiors or lessers) they just fulfil their position.
