Has anyone ever had their horses personality or character change literally over night? Not sure how to explain this or even if I'm asking correctly but here goes. Pony super little thing. You can do anything to or around him. He's the type who likes people and shows it or hates them and shows it. With me he's always very kind and forgiving. I can pretty much do anything with him. Even my vet said how easy he is and how he allows her to do pretty much anything. Then yesterday he didn't allow me to touch his face (usually he loves when I give him a rub between his eyes) and was just very very head shy (not him at all). I thought ok strange but he just had his flu vaccine so I left him be. Same thing again today. I of course asked the grooms if anything happened, nothing happened so I've been told. It's basically an over night thing. He is fine when I go to put his halter on, or rub his neck or anywhere else on his body just not his face, and that's his fav spot to be rubbed. Anyone else had a horse do the same type of thing?
