Hi, i was just wondering what people's thoughts were on potassium bromide and using it as a calmer for hot horses, or when taking horses to a show if it is very effective. If used a number of times can it have any side effects or can horses become immune to it? otherwise does anyone no of any other effective calmers that can be used for horses that tend to "flip" out a bit at new places? i no this topic has been posted many time before, but i just wanted to hear people views, oppinions and actual dirst hand experience stories about using potassium bromide. Cheers!
