Bleeding from the nose most commonly occurs due to trauma, such as a kick or bang to the head. In some rarer cases a nosebleed can indicate serious underlying disease (even if the first nosebleed seems very insignificant).
What to do:
- If the bleed is severe keep the horse calm and quiet and contact your vet immediately.
- In other cases that have no obvious cause (such as cut inside the nostril), you should contact your vet for further advice without delay.
