Chaff in My Head Cannon: Herd Mentality in Equestria · 4:26am Jul 12th, 2016
Bare with me here, this is probably going to get weird.
Ponies, and horses in general, are herd animals by nature. They follow similar dynamics to wolf packs, though it's a much more fluid arrangement. Whereas wolf packs tend to be linear, pony herds are more like tiers of dominance, with more than one pony able to be at any one tier.
