I just got a new male guinea pig about 8-10 weeks old, my other was born in June i believe. well Chewie (being the older) is acting very dominant, with the rumblestrutting, nose raising contest, licking at ears, etc. Well sometimes Peanut puts forth a little effort at being dominant and not submitting and I'm afraid of is that once Peanut is completely comfortable with being around in the new place that he's going to start acting more and more dominant behavior, any suggestions on that?
