Question about Stewie's behavior

Stewie has been with me a little over a year now, he has not shown one sign of aggression towards myself or Viv or anyone for that matter but he does do this one thing that is odd.
If he is on my lap and Viv wants to get up he will bop his head towards her, like he is saying nope she is mine. Viv is super sensitive and get in a tizzy over this. If I move him and pick Viv up and put her on my lap he will come over and cuddle into her.
At first I thought she was catching him off guard since he only has vision in one eye but he has done it about four or five times now, he doesn't go after her or growl just a little head bop.
Any thoughts?

First guess: he's kind of wishing trying and in a habit now about pushing her button/edge (territory) questioning... He sounds not very committed to his offensive, but unable (or unware of it?) to not do it...

I hope someone else zooms in with a more definitive idea!

(I think you are amazing to pick up on these things! I am dumbfounded by they things I don't see going on between my dogs that others do!)

He's asserting a little dominance, but not enough to be aggressive. I call it King of The Mountain. Mine do it too. Lap is prime real estate!

That would make sense. I will say to Stewie when he does it you can't always be King of The Hill.
