When horses blow air through their nose, they may be clearing dust, smells, or irritation from their nostrils. But it can also be a form of communication. A soft blow or snort may show curiosity, relaxation, or alertness, depending on the situation.
Horses use their sense of smell to understand the world around them, so blowing air helps them process scents and react to their environment. If it happens often with coughing, discharge, or breathing trouble, a veterinarian should check it.
