Chronic Ear Disease in Dogs: Welfare and Management

Otitis externa and media are common and painful conditions in dogs, particularly in predisposed breeds, requiring systematic management of underlying causes for sustained welfare improvement.

Key Facts

Chronic otitis affects approximately 10-20% of dogs presenting to veterinary practices
Spaniel breeds, Labrador Retrievers, and other pendulous-eared breeds are predisposed
Primary causes include allergies, hypothyroidism, and foreign bodies; perpetuating factors include infections
Pseudomonas aeruginosa otitis is notoriously difficult to treat and may require specialist referral
Surgical intervention including total ear canal ablation (TECA) may be required for end-stage otitis

Welfare Considerations

Chronic ear disease causes constant discomfort from inflammation, infection, and pruritus. Dogs with otitis may shake their heads hundreds of times daily, develop haematomas from ear-flap trauma, and show pain responses when ears are touched. The chronic nature of recurrent otitis means affected dogs may spend years in varying degrees of ear discomfort. Many cases are managed symptomatically without addressing underlying causes, leading to repeated cycles of infection and treatment. Systematic investigation and management of primary causes, particularly allergic disease, provides better long-term welfare outcomes.

What You Can Do

Seek veterinary investigation of underlying causes for any dog with recurrent ear infections
Follow complete treatment courses for ear infections, including regular cytology monitoring
Discuss referral to a veterinary dermatologist if otitis is not resolving with first-line treatment
Learn to recognise early signs of ear discomfort in your dog to enable earlier intervention in flare-ups
