Brown discharge in the Border Collie’s ears may be caused by bacterial infection or parasitic infection. We need to take it to the hospital for an ear canal examination. No matter what kind of infection, it needs to be treated in time. After treatment, care should be taken every day to prevent recurrence.

Tip:

The dog’s ear canal is L-shaped. When we remove the ears, we can directly dig them to the bottom without worrying about damaging the ears.
