So today I was walking around in the arena because frost had ran away due to me using a different coloured tarp during desensitisation. (Some horse had numbered 1ed over it). I heard some rustling in the bushes nearby, and saw dasher! I haltered him and brought him in for a checkup. He was perfectly fine, and I brought him into a spare stall until Cosima (@HorseExpert4eva) came to pick him up.
