Ear Infections (Otitis Externa)
Chronic or recurrent inflammation of the external ear canal, often due to breed-specific ear conformation.
Detailed Description
Otitis externa is inflammation of the external ear canal, commonly caused by bacteria or yeast. Dogs with long, pendulous ears are predisposed because their ear conformation traps moisture and debris, creating an environment conducive to infection. Chronic infections can lead to pain, hearing loss, and secondary complications.
Common Symptoms
- Head shaking
- Ear scratching
- Redness, odor, or discharge from ears
Management Options
- Topical antimicrobials or antifungals
- Ear cleaning
- Addressing underlying allergies if present
