Hi Rob, thanks for using Petco Pet Education Center, formerly Petcoach. It sounds like Arlo has an ear hematoma. These are when the ear fills with blood and can be quite painful. A lot of time it can be secondary to an ear infection. It is important to bring Arlo to a veterinarian to have them treat this condition.

    This maybe a hematoma which is a blood clot from shaking or scratching m. This is usually secondary to an infection or allergy. It is worth a trip to your vet for medication to treat it but not on an emergency basis.
