Dominance Behaviour

[GPcrazy]

My 2 girls are busy having an awesome floor time, and I'm sitting in watching which is so fun! I'm seeing sime interesting dominance displays that I haven't noticed before.
Patches keeps pushing nia's chin up high. Does that mean Patches is dominant or Nia? Is it the highest chin that wins or the one doing the pushing?

Also, with butt sniffing, is it the one doing the sniffing or the one beig sniffed that's showing dominance?

Yes, pushing up the chin of an underpiggy is establishing/re-enforcing dominance.
