Because damage remains marked on a creature until the damage is removed as the turn ends, nonlethal damage dealt to a Dog you control may become lethal if Pack Leader leaves the battlefield during that turn.

Once Pack Leader attacks, its effect prevents damage that would be dealt to Dogs you control even if Pack Leader leaves the battlefield.
