Are they ready to fight or showing who is boss?

I noticed my piggies making noises and stomping from side to side - I got a bit worried! One of the beds was in the washing machine so maybe that could have been a factor as they like their own space but they were both doing it so do you think they are clashing?

They generally get on and comfort each other when big bad mummy comes over with fresh bedding/food.

Looks like mild dominance behaviour (rumblestrutting).

Thank you, is there a chance it will get worse and is there anything I can do to prevent any ego problems?
