Horse Body Language
The horse can indicate its own feelings in a number of ways and the ears are a good indication of what is going through a horse's mind.
Ears Alert and Forward
Ears pricked alert and facing forward indicate the horse is happy and interested.
Ears Flat Back
Ears laid flat back against the neck show the horse is unhappy or annoyed.
Ears lowered slightly to the sides show the horse is relaxed, bored or could indicate that it feels unwell.
Flickering ears indicate the horse is listening and attentive.
