In all the years we've been in the horse business, this has happened once. Several years ago, we sold Flipper to a local guy who was just looking for a horse that he could ride occasionally and that's the type Flipper is. Anyway, he is a pretty hard keeper TB and if you even think about changing his feed, he'll drop weight. Anyway a few weeks after this guy took him home, we were driving past and noticed that he seemed a little thin. After that, we would check up on him often and found out that they guy was feeding like half a ration of crappy grass hay to him every other day. Needless to say, Dad confronted the guy (I was living in Amarillo at the time) and said that if you aren't going to feed the horse, we're taking him back. So Flipper came back home in our trailer and got to enjoy all the good food he could eat after that. He still isn't fat, probably never will be, but he is slick, shiny, and healthy in his forever home. It would just be cruel to risk putting him through something like that again so he can live out the remainder of his retirement in our pasture.
