Aural Haematoma in Dogs: Welfare Management

Aural haematoma — a blood-filled swelling of the ear flap — is a painful condition in dogs usually secondary to ear disease, with welfare implications from the primary and secondary conditions.

Key Facts

Aural haematoma forms when vigorous head-shaking or scratching ruptures blood vessels in the ear pinna cartilage
It is almost always secondary to an underlying cause such as otitis externa, ear mites or allergic skin disease
Untreated haematomas may resolve slowly but cause permanent ear deformity ('cauliflower ear') through fibrosis
Treatment options include drainage with indwelling drain, surgical correction or, in some cases, conservative management

Welfare Considerations

The welfare impact of aural haematoma is twofold: the haematoma itself causes pain and discomfort through swelling and pressure, while the underlying ear disease causing the head-shaking is often chronically painful and pruritic. Addressing only the haematoma without treating the underlying cause leads to recurrence. Pain management is essential throughout — the ear is highly innervated and even gentle handling of an affected pinna causes distress in affected dogs.

What You Can Do

Seek veterinary assessment promptly — delay increases risk of permanent ear deformity
Treat the underlying cause (ear infection, mites, allergy) alongside the haematoma
Prevent head-shaking with buster collar if needed while awaiting treatment
Monitor for recurrence after treatment and re-investigate for persistent underlying ear disease
