Rumble strutting?

[Bramble&Dot]

Hi,
I have two sows - Bramble and Dot, Bramble is the bigger pig so you would assume she is dominant but Dot is a bit of a diva and has a big character so neither of them is really dominant, anyways they seem to rumble strut a couple of times a day they do it at the same time and their walking slows down they get closer to the floor and make a low grumbling noise they move and do it or sit still and wiggle their bums. But occasionally in the middle of this they will popcorn whilst this grumbling, just wondering if it's angru behaviour or not? As I know popcorning is a happy thing?
Thanks

It is either mild dominance behaviour or connected to them coming into season, depending on how long you have had them (the dominance phase of establishing a working group in new surroundings takes on average about two weeks, but can take longer).
By their behaviour, they are obviously still sub-teenage babies?

We got them late October last year they were 2 months (ish) when we got them so they are getting on for 5 months now.
I think it could be dominance but I'm just confused about the popcorning!

It is still mild dominance behaviour, but it is not serious and the popcorning clearly proves that your girls are having fun and are still best of friends. Your girls are just entering the more hormonal stages of their teenage months where a stronger season can trigger some more dominance behaviours.

Interpreting behaviours is very difficult - social interaction has got a vocal, a body language and a scent (pheromone) component, but it has also a strong situational component. That is why audio and even video guides can't give you the whole information and can be very misleading.

When sows have strong seasons life can get quite chaotic in a cage.
Be prepared for chasing, humping and a lot of noise.
It’s guaranteed to make new slaves panic.
Your girls sound as if they have a lovely friendship

I have 2 boars and the one that tends to be the dominant one has started rumblestrutting and trying to mount the other one alot more. Read an article which made me think it is caused by a peak of testosterone.
