Trimming a horse's ears is somewhat controversial. Some people believe the ears should never be trimmed. Others will remove the hair from both the outside and inside of the ear. The traditional method, however, is to hold the horse's ear together and trim off only the untidy, excess hair. Trimming inside the ear removes the horse's protection from flies and can increase the risk of ear mites. A horse with trimmed ears should wear a fly hood when turned out. It's much easier not to trim inside the ear in the first place. Trimming only the excess looks just as neat.
