The dog's scratches are thin and deep, accompanied by a certain amount of pain, and then gradually become swollen, and may even cause bleeding in severe cases. Ordinary scratches usually result in overall bleeding and deep wounds. After being injured, you must disinfect and stop bleeding in time to prevent infection from being exposed to the air for a long time. In addition, if you are scratched by a dog, you must go to the hospital for vaccination within 24 hours to avoid affecting your health.
