Do our pet dogs see us as a "Family Unit" or a "Pack with a Hierarchy"?

Do our pet dogs see us more of a family unit rather than a pack with a hierarchy or both? I've just been wondering about this question for awhile now but do our pet dogs see us as their pack leaders and still have that instinct that their wild cousins the wolves have like dogs see us as their pack leaders and have us guide them threw things, etc. or lost their "wolf" instinct that they needed to survive in the wild or do they just see us as a member of the family or both? I've even saw something on this dog documentary about our pet dogs doing stuff their "own" wild cousins and our "wild" relatives couldn't do like dogs like us to guide them to things just like our own human offspring does were as a wolf or a chimp or any animal for that matter doesn't give a damn what we want them to do for us even though we can train wild animals and it's possible but dogs could do much more things than any other animal on the planet can't do but back to my question: does dogs see us a family unit or a pack with hierarchy?
