Chronic Ear Infections in Dogs
Chronic ear infections cause ongoing pain, itching, and odor for many dogs, especially breeds with floppy ears or narrow ear canals. At Animal Surgical Care of PA, we help identify when medical management isn't enough and surgical intervention may offer lasting relief.
Repeated ear infections often stem from an underlying cause such as allergies, moisture retention, or anatomical narrowing of the ear canal that makes it difficult for infections to clear completely. Over time, chronic inflammation can thicken and scar the canal tissue, making future infections even harder to treat with medication alone.
Signs to watch for include head shaking, scratching at the ears, a strong odor, redness, and visible discharge. If your dog has been on repeated rounds of ear medication without lasting improvement, it may be time for a more thorough evaluation using otoscopy and imaging.
For dogs with narrowed or scarred canals, procedures such as ZEP lateral ear canal resection can improve airflow and make future cleaning and treatment far more effective. In more severe, end-stage cases, Total Ear Canal Ablation (TECA) may be recommended to permanently resolve chronic pain and infection.
If your dog's ear infections keep coming back despite treatment, contact Animal Surgical Care of PA at (484) 886-8612 to discuss whether surgical evaluation is the right next step.
