Annie is the perfect size for a rider who is ready to graduate to a bigger horse but not quite ready for the big horses. Annie is a sweetheart but is stubborn. My son and my husband have been working with her, and her stubborness is improving. She is not afraid of anything, has been in town, in parades, and my husband has roped off of her in the feed yard. A small adult would get along with her great An aggressive child would be fine also, but she does have a stubborn streak when trying to move out away from other horses. We have too many other horses that need the time. She would make a great lead-line or beginner pony for someone to ride beside as she doesn't like to ride away from other horses very well.
