It's called The Flehmen response , a reaction to a sight or scent an animal knows is familiar with or interested in . Now where are the comments " poor horse is thirsty " " poor horses left standing for hours " . Notice the horses are attended to before the Troopers ! The Trooper in camo got a shower care of the horse , that's called sharing 😂😂😂
Shame they have such precious hearts an animal is one of the most loving creatures one could get they like us respond to love kindness and care so special to see this horse smile once having received a drink ❤
