Dog Ear Infections: Prevention and Welfare Management of a Common Problem

Otitis externa (ear infection) is among the most common veterinary conditions in dogs, causing significant discomfort. Understanding prevention and management improves welfare.

Key Facts

Otitis externa affects approximately 10-20% of dogs presenting to veterinary practices
Predisposing factors include floppy ears, narrow ear canals, allergies, and regular swimming
Bacterial and yeast infections are the most common causes, often secondary to primary disease
Signs include head shaking, pawing at the ear, odour, discharge, and ear sensitivity
Chronic ear infections can progress to otitis media (middle ear) causing neurological signs
The primary cause (allergy, anatomical abnormality) must be addressed alongside treatment of infection

Welfare Considerations

Ear infections cause genuine pain and discomfort that significantly affects quality of life. Dogs with chronic ear disease may shake their heads continuously, resist handling around the ears, and show signs of distress. The welfare failure most commonly seen is treating infection without addressing the underlying cause — allergic dogs with recurrent ear infections treated repeatedly with topical antibiotics without allergy investigation continue to suffer preventably. Welfare-centred ear management involves diagnosis of the primary cause (particularly allergy), appropriate treatment, regular ear cleaning as indicated, and referral to a dermatologist for refractory cases.

What You Can Do

Seek veterinary assessment for any dog showing ear-related signs — do not use over-the-counter products without diagnosis
Ask your vet about investigating the underlying cause if your dog has recurrent ear infections
Clean ears only as directed — over-cleaning can damage the ear canal and worsen conditions
Dry ears carefully after swimming and bathing for dogs prone to ear infections
Request dermatology referral for dogs with ongoing ear disease despite appropriate treatment
