The 'heart" icon shows the horse's health bar. Feeding and brushing your horse regularly affects its health. If you neglect your horse, its health will go down. Unhealthy horses tend to die earlier than horses that are well looked after.
The prize money won by the horse is shown next to the "Cup" icon
The smiley face bar shows how happy your horse currently is. Happiness can be improved via brushing, treats and winning races!
The bed icon shows how tired your horse is. Fatigue will affect your horse's racing performance. Different horses will fatigue at different rates. If your horse is fatigued and performing poorly, might be time to give them a rest. Treats available from the shop can also assist horses suffering from fatigue.
Horse strength or endurance will display as either a description (e.g. poor) or as stars (if you have the Horse Performance analyzer). This will give you a better idea of your horse's performance attributes. Strength is the 'bicep curl' icon and endurance is the 'treadmill' icon.
If you have the Horse Performance Analyser, you will be able to see your horse's track preferences. This will help you pick races suited to your horses abilities.
The magic wand icon shows any special effects your horse currently has. This might be effects from saddles or shoes, treats, boosters etc.
