I find that the dominance can change after bonding though. When i bonded opal and the benjamin, the benjamin was humping Opal all the time....and wanting to be groomed, but now Opal is the dominant one. She bosses the benjamin around, if he is having a drink, and she wants a drink, she will box his head out of the way so she can get a drink first. He is stupid and just lets her, plus she humps him all the time when i go to feed them. They dont fight though, she just feels the need to assert her dominance over him. Poor bun. :lol:
