My Jo-Jo does some of the same things. When he's uneasy he will sit on my feet but that can also mean he has to go outside to potty but it's up to me to figure out
He also 'gets after' Riley when it's bedtime. He will herd him towards the bedroom, growling and nipping the whole way...poor Riley, he just wants to go to bed. I'm not sure if it's dominance behavior, they don't try to dominate each other any other time.
