Based on the location, I am concerned that the left anal sac may be the cause for the bleeding. Dogs can develop anal sac abscesses, which is an infection of the anal sac (there are two located at the margin of the anus) that can rupture to the outside. These can be painful and will often require antibiotics and anti-inflammatory medication to manage pain and allow healing. The other potential is an anal sac mass. Due to Ben's age I would be very concerned for this. Unfortunately there is not much that can be done from home for either of these conditions. It would be recommended to try to find the closest veterinarian to you and have Ben seen. If it is an anal sac mass, these often require surgery and have the potential to be malignant cancers.
