With a dog, I know how to do this. If they are sleeping in your path, don't go around, but poke them until they get up. If it's really bad (and you are sure they won't bite you) hold their muzzle to the ground until their body languages shows that they submit. Our Akita is a senior citizen now, and has not made a bid for my spot for quite awhile.
My son, on the other hand, has apparently decided that I am ready for retirement. And I don't have any idea what the parenting equivalent is of holding his muzzle to the ground.
