When a horse leans on you, it is an indication that the horse trusts and feels comfortable with you. It is also a sign of affection, as horses naturally lean against other animals in their herd for comfort and security. Leaning can be seen when a horse stands alongside you or nudges its head into your shoulder or torso as if asking to be rubbed. Horses may also put their heads over your head and shoulders while standing still, which indicates an even greater level of trust and connection. When a horse leans on us, it's important to take the time to appreciate this special moment - it's one that doesn't come around often!
