The Spaniels could tell I was getting dressed in Off-Farm clothes; lately they're more concerned when I leave, so I told them "It's Auntie Vet. Auntie Vet is coming." They immediately switched from "you're LEAVING us!!" behaviors (slinking around, clinging to me, and sitting sadly in their crates) to excited anticipation behavior (watching out the window, Excited Tristan Noises, and rowroos).
