An aural hematoma looks alarming — a dog's ear flap suddenly balloons into a squishy, blood-filled pillow. It happens when a burst blood vessel bleeds between the layers of the ear, almost always because the dog was shaking or scratching its head hard over an ear infection or allergy. It's rarely a true emergency, but it won't resolve well on its own, and left untreated it scars into a shrivelled 'cauliflower ear.' Here's what treatment costs in Canada, the two main approaches, and why the ear infection behind it matters for your bill.
What it costs in Canada
| Scenario | Typical cost (CAD) |
|---|---|
| Exam + diagnosis | ~$60–$150 |
| Draining + steroid/medical management | ~$150–$500 |
| Surgical correction (incision + quilting sutures, anesthesia) | ~$600–$1,500 |
| Treating the underlying ear infection/allergy | ~$100–$400 |
| Recheck + suture/drain removal | ~$80–$200 |
These figures are estimates for general guidance only, not quotes, compiled from publicly available Canadian veterinary pricing. The single biggest cost driver is method: repeated draining with a steroid is cheapest up front but can recur, while surgery costs more and has the lowest recurrence. Whichever route you take, budget for the underlying ear infection — treating the hematoma without fixing the cause invites a repeat on the same or other ear. See How we estimated these costs.
With insurance vs paying out of pocket
| Scenario | You pay | Insurer pays |
|---|---|---|
| No insurance | Full cost of treatment + the underlying ear condition | $0 |
| Standard comprehensive policy | Deductible + co-insurance share | Generally covered as illness/injury (if not pre-existing) |
| Recurring ear infections diagnosed before enrolment | Likely the full ear-related cost | May exclude the ear as pre-existing |
| Accident-only policy | Usually full cost | Typically not covered — this is illness-driven, not an accident |
What an aural hematoma actually is
The ear flap (pinna) is a sandwich of skin over cartilage with small blood vessels running through it. When a dog shakes or scratches its head violently — the way it does with an itchy, infected ear — a vessel can rupture and bleed into the space between the layers, ballooning the flap with blood and serum. It's most common in dogs (especially floppy-eared breeds) but happens in cats too. It's uncomfortable and looks dramatic, but the urgency is about preventing permanent scarring and stopping the cause, not about a life-threatening emergency.
Draining vs surgery: the two approaches
Medical management means draining the fluid with a needle or small drain and using a steroid (oral or injected) to calm the inflammation. It's less expensive and avoids anesthesia, but the ear can refill, sometimes needing several rounds. Surgery opens the flap, clears the clot, and places 'quilting' sutures that press the layers back together so they heal flat — it costs more and needs anesthesia, but has the lowest recurrence and the best cosmetic result. Your vet will weigh your dog's size, the hematoma's size, anesthetic risk, and cost. Neither is wrong; they're a cost-versus-recurrence trade-off.
The catch: you're really treating two things
An aural hematoma is a symptom. The head-shaking that caused it almost always traces to an ear infection, ear mites, or an underlying allergy. If you fix the hematoma but not the itch, the dog keeps shaking and you're back at the clinic — same ear or the other one. That's why the realistic budget includes ear cytology, cleaning, and medication for the primary problem. For chronically allergic dogs, this can be a recurring theme, which is exactly the kind of thing worth having covered before it's on the record.
The insurance angle
Because an aural hematoma is illness/injury-driven rather than elective, comprehensive pet insurance generally covers it — the treatment and, importantly, the underlying ear infection — at your reimbursement rate after the deductible, as long as the ear problem wasn't pre-existing. That's the key timing issue: if your dog already has a documented history of chronic ear infections before you enrol, an insurer may exclude the ear. Insuring a young dog with healthy ears is the way to keep this common, recurrence-prone problem covered. Accident-only plans usually won't pay, since this is driven by illness, not a single accident.

Considering insurance?
An ear hematoma is a $300–$1,500 fix — but the ear infection or allergy behind it can make it a recurring bill. Comprehensive insurance covers both, as long as the ear isn't already pre-existing. Insure a young, healthy-eared dog and compare Canadian plans.
