The horse is an animal the player can receive in Harvest Moon 64. The horse can be obtained as early as the first day on the farm. If the player walks onto Green Ranch at any time during the day, Ann and her father will give them a colt to keep. It will take a total of one season (20 days) for the colt to grow into a horse. During this time, it may not be ridden and it will not wear saddle bags.
Once grown, the horse can participate in the Horse Races. To gain its affection and give it high stamina for the races, the horse should be brushed, talked to, whistled for, and ridden daily. Alternatively, affection can be lost if the player hits it with a tool and affection points will be lost every night the player sleeps.
