I used Mare-Aculous on my appaloosa mare beauty about a year and a half ago. Before using this product she would be aggressive, charge at me, and nip at me and my geldings most of the time. However, after using a bag of the product she did a complete 180. She has mellowed out so much over the last year or so and it is INCREDIBLE! If I had to recommend any product for a “moody mare” owner this would be it. Now I can happily say that I do not have a moody mare… unless she doesn’t get fed on time! ?
