Talking about snacks, my horses both have sweet tooths. I limit it but I do treat at times. Neither cares for carrots. Okie likes the horse bars and apples. Sarah Lee likes everything, but esp peppermints.
Hee, my Beren will do about anything for a peppermint. Just crinkle the wrapper and he perks up. Of course, this is the same horse that likes burgers and Chik-Fil-A sandwiches, not that he's allowed to get them. He's reached out and taken a chunk of mine on more than one occasion.
