Nosebleeds in pets are usually caused by injury, infection, bleeding disorders, foreign objects, or tumors. Apply an ice pack wrapped in cloth to the nose. Place steady pressure on the bleeding nostril using a clean cloth or gauze. Keep the animal as quiet and still as possible.
If the bleeding does not stop or is the result of anything but simple trauma, or there is no obvious reason for the bleeding, take the animal to a veterinarian immediately for an exam. A small amount of blood from one nostril may be an early sign of a tumor.
