Hello,
Please provide more information. Like what is bleeding? It is best to see a vet if you think this might be an emergency or if the bleeding persists or is severe.

Good morning. Is this a wound? Or is it raw from irritation? Allergic symptom? Depending on what the cause is, the treatment is different. My suggestion would be to get him to the vet right away to find out what is going on, but in the meantime try to get him comfortable.
