In dogs who are prone to severe ear infections, such as cocker spaniels and bulldogs, the constant inflammation and infection in the ear can result in thickening of the ear skin and cartilage over time. The abnormally thickened tissue makes it harder to treat the ear infection inside, and the inflammation continues. The upper ear still has an opening into the ear canal, though the opening is swollen and difficult to insert medication into. The lower ear, however, is an end-stage ear. No amount of anti-inflammatory steroids or medications or antibiotics will fix that ear now. At this stage, surgery such as a total ear canal ablation to remove the ruined ear canal and bones of the middle ear is warranted. This option was discussed with this owner, but they have declined at this time.
This is why it is so important to go to the vet when you first notice a problem and not wait.
