I have noticed today that my new piggy is rumblestrutting when she gets near the dominant piggy. My dominant pig does not really seem to have a reaction to this and just lets the new piggy do her thing.
Is rumblestrutting only used to show dominance or can it mean something else? & Could a previously dominant pig of a herd become submissive when a new piggy is added and the hierarchy is switched up?
Just curious. I have had no issues of fighting or even teeth chattering but am very interested in guinea pig behaviors.
