What Your Dog's Ears Are Telling You

Of all the areas of a dog's body that get regular attention during a professional groom, the ears are the ones that most consistently reveal something worth knowing. Not because ear problems are inevitable — many dogs go their entire lives without a single ear infection — but because the ear is a uniquely enclosed, warm, and moist environment that is highly sensitive to changes in health, hygiene, and the balance of the microorganisms that naturally inhabit it. An experienced groomer who looks carefully into a dog's ears at every appointment is doing something genuinely valuable — not just cleaning, but monitoring. And owners who know what healthy ears look like and what the warning signs of trouble are can catch problems early, before a minor imbalance becomes a painful infection requiring veterinary treatment.

At Woofz N Wagz, ear care is part of every grooming appointment — and it is one of the areas where we most frequently identify something worth communicating to the owner. Here is everything you need to know about your dog's ears.

What Healthy Ears Look Like

Before you can recognize a problem, you need to know what normal looks like. A healthy dog ear has the following characteristics.

The skin inside the ear flap and the visible portion of the ear canal is pale pink — not red, not inflamed, not irritated. The color is even and consistent without patches of deeper redness or angry-looking tissue.

There is a small amount of light brown waxy discharge. This is normal and healthy — a dog's ears produce a natural wax that plays a role in protecting the ear canal. The key word is small. A light coating of pale to medium brown wax is normal. Dark brown, black, yellow, or green discharge, or any amount that seems excessive, is not.

The ear smells clean or very mildly waxy. A healthy ear has essentially no odor, or a very faint neutral smell. Any distinct, unpleasant odor — sour, sweet, musty, or strongly pungent — is a significant warning sign.

The dog shows no discomfort when the ear is handled. A dog with healthy ears can have their ears touched, lifted, and examined without flinching, pulling away, or showing signs of pain. Sensitivity or a pain response to ear handling is always worth investigating.

There is no hair growth deep within the ear canal that is causing problems. Some breeds grow hair inside the ear canal — Poodles, Bichons, Schnauzers, and Doodle crosses among others — and this hair can trap debris and moisture if not managed. Healthy ears in these breeds have been appropriately maintained, either through professional ear plucking where indicated or regular monitoring.

Common Ear Problems in Dogs

Ear Infections — Otitis Externa

Ear infection — medically called otitis externa when it involves the outer ear canal — is one of the most common health conditions in dogs. It occurs when the natural balance of the ear's microbiome is disrupted and bacteria, yeast, or a combination of both proliferate beyond normal levels. The result is inflammation, discharge, odor, and discomfort that ranges from mild to severe.

Certain dogs are significantly more prone to ear infections than others. The factors that increase risk include the following.

Floppy ears. Dogs with pendulous ear flaps — Cocker Spaniels, Basset Hounds, Golden Retrievers, Doodles — have a reduced airflow into the ear canal compared to dogs with upright ears. The warm, enclosed environment created by the drooping ear flap is an ideal breeding ground for the organisms that cause infection.

Hair in the ear canal. As mentioned above, breeds that grow hair inside the ear canal can trap moisture and debris that contribute to infection if the hair is not managed appropriately.

Allergies. This is one of the most important and most frequently overlooked factors. Chronic or recurrent ear infections are one of the most consistent symptoms of underlying allergies in dogs — both environmental and food-related. A dog that has repeated ear infections despite appropriate treatment should be evaluated for allergies, because treating the ear infections without addressing the underlying allergic inflammation is a cycle that never truly resolves.

Swimming. Dogs that swim frequently introduce water into the ear canal repeatedly, and if this moisture is not adequately dried after each swimming session, it creates the moist environment in which infection-causing organisms thrive.

Hormonal imbalances. Hypothyroidism and other endocrine disorders can predispose dogs to recurrent ear infections by altering the skin's natural defense mechanisms.

Signs of Ear Infection

The signs of an ear infection are usually fairly obvious once they have progressed, but catching them early — before the dog is in significant discomfort — requires knowing what to look for.

Head shaking. A dog that shakes their head more than usual, particularly if the shaking is repetitive or seems to be focused on one side, is often responding to ear discomfort.

Scratching at the ear or side of the head. Using a paw to scratch at the ear, or rubbing the side of the head along the floor or furniture, is a common behavioral response to ear irritation or pain.

Tilting the head. Persistent head tilting — holding the head consistently to one side — can indicate inner or middle ear involvement and is a sign that warrants prompt veterinary attention.

Odor from the ear. As noted above, any distinct unpleasant smell from the ear is a warning sign. The specific character of the odor can provide useful information — a sweet or yeasty smell is typical of a yeast infection, while a more pungent or putrid odor suggests bacterial infection.

Dark or excessive discharge. An increase in discharge volume, a change in color toward dark brown, black, yellow, or green, or discharge that has a different consistency than the light wax that is normal — thicker, more fluid, or crumbly — are all signs of infection.

Pain on ear handling. A dog that flinches, pulls away, cries, or snaps when their ear is touched is telling you their ear is painful. This is a clear signal for veterinary evaluation.

Redness or swelling. Visible inflammation inside the ear flap or at the entrance to the ear canal, or swelling of the ear flap itself — which may indicate a separate condition called an aural hematoma — are signs that the ear needs professional attention.

Ear Mites

Ear mites — Otodectes cynotis — are tiny parasitic mites that live in the ear canal and cause intense irritation. They are more common in puppies and in cats than in adult dogs but can affect dogs of any age and should be considered in any dog showing ear discomfort, particularly if there is a dark, crumbly discharge that is sometimes described as looking like coffee grounds.

Ear mites are highly contagious between animals — if one pet in the household has them, all pets should be treated. They are diagnosed by your veterinarian and treated with appropriate antiparasitic medication. Ear cleaning alone does not eliminate ear mites and should not be attempted as a substitute for veterinary treatment.

Aural Hematoma

An aural hematoma is a collection of blood between the layers of the ear flap, creating a soft, fluid-filled swelling. It is almost always caused by the trauma of repeated head shaking or scratching — the force of the movement ruptures small blood vessels within the ear flap. This means that an aural hematoma is typically a secondary consequence of something causing ear discomfort rather than a primary problem — and treating the hematoma without identifying and addressing the underlying cause will often result in recurrence.

Aural hematomas require veterinary treatment — either aspiration of the fluid or surgical drainage and suturing. Left untreated they can resolve on their own but often result in permanent deformity of the ear flap — the characteristic cauliflower ear appearance that is seen in chronically affected dogs.

Breed Specific Ear Considerations

Different breeds have different ear anatomies and different baseline risks that shape the specific ear care approach they need.

Floppy-eared breeds — Cocker Spaniels, Basset Hounds, Bloodhounds, Golden Retrievers, Labradors, most Doodle crosses — need more frequent ear cleaning and monitoring than upright-eared breeds. The reduced airflow into their ear canal creates conditions that favor the development of infection, and a consistent cleaning routine is a meaningful preventive measure.

Breeds with heavy hair growth inside the ear canal — Poodles, Bichons, Schnauzers, Maltese, and most Doodle crosses — require specific management of this hair. The question of whether to pluck ear hair is one that divides groomers and veterinarians somewhat, and the right approach varies by individual dog. In dogs that are prone to ear infections, plucking excess hair from the canal can improve airflow and reduce debris trapping. In dogs that are not prone to infection and whose ear canal hair is not causing problems, routine plucking may cause more irritation than benefit. At Woofz N Wagz we assess this individually for each dog and discuss our approach with the owner rather than applying a blanket policy.

Upright-eared breeds — German Shepherds, Huskies, French Bulldogs, Chihuahuas — generally have better natural airflow into the ear canal and are less prone to the moisture-related infections that affect floppy-eared breeds. They still benefit from regular monitoring and appropriate cleaning, but the baseline risk is lower.

Breeds with very narrow or deeply folded ear canals — some Shar Peis, some Bulldogs — can have structural features that impair drainage and increase infection risk regardless of how well the ears are maintained externally.

How Professional Grooming Supports Ear Health

At every Woofz N Wagz grooming appointment, we include the following as standard ear care.

Visual inspection of the ear flap and visible ear canal. We look at the color of the skin, the character and volume of any discharge, and any signs of inflammation, redness, or abnormal tissue.

Cleaning of the ear flap and the accessible portion of the ear canal using an appropriate dog-safe ear cleaning solution. We clean only what is visible and accessible — we do not probe deeply into the ear canal, which is a task for veterinary professionals.

Removal of excess hair from the ear opening where appropriate — assessed individually for each dog based on their specific anatomy, coat type, and history.

Communication with the owner about anything we observe that warrants attention or a veterinary follow-up.

What we cannot do — and what no groomer should attempt — is treat an ear infection. If we observe signs of infection during a groom, we will always tell you clearly and recommend a veterinary visit promptly. Putting cleaning solution into an infected ear can be painful and in some cases harmful — particularly if the eardrum has been compromised. Ear infections require veterinary diagnosis and appropriate medication, and we take our responsibility to refer appropriately seriously.

Home Ear Care Between Appointments

Regular home ear monitoring is simple and takes only a minute or two at each check. Lift your dog's ear flap, look at the visible skin, note the color and any discharge, and give it a brief smell. If everything looks and smells normal, nothing needs to be done. If anything has changed from what is normal for your dog, note it and mention it at the next grooming appointment or contact your veterinarian.

For dogs with floppy ears or a history of ear infections, a gentle clean of the ear flap with an appropriate dog-safe ear cleaning solution once every one to two weeks is a reasonable preventive routine. Apply the solution to a cotton ball and wipe the visible portions of the ear — never insert a cotton swab into the ear canal.

After swimming or bathing, dry the ear flap thoroughly and allow the ear canal to air dry as completely as possible. For dogs that swim frequently and are prone to infections, a veterinary-recommended ear drying solution applied after every swim can significantly reduce the moisture-related infection risk.

The Bottom Line

Your dog's ears are telling you something at every grooming appointment and every home check — and learning to read what they are saying is one of the most valuable things you can do for your dog's long-term health. Healthy ears need monitoring and appropriate cleaning. Ears showing early signs of trouble need prompt attention before a minor imbalance becomes a painful infection. And ears with established infections need veterinary care that no amount of grooming can substitute for.

💡 Pro Tip: If your dog is prone to ear infections, keep a simple log of when infections occur, which ear is affected, and what the discharge looked like. Over time this log often reveals patterns — seasonal triggers, correlation with swimming or bathing, connection to dietary changes — that provide valuable information for your veterinarian in identifying and addressing the underlying cause rather than just treating each infection in isolation.

At Woofz N Wagz we take ear health seriously at every appointment — and we are always honest with you about what we see. Your dog's ears matter, and we are here to help you keep them healthy. 🐾
