Drop ears don’t cause infections by themselves, but they do hold warm air against the canal — and that small shift changes how I think about routine checks.
Why would a flap of skin matter that much? It helps to picture what’s underneath.
How a covered canal stays damp longer
A dog’s ear canal makes a sharp L-turn before it reaches the eardrum, and that bend already limits airflow. When a long pinna lies over the opening, it acts a bit like a lid. Moisture from swimming, bathing, or humid weather evaporates more slowly, and wax and normal debris sit undisturbed.
The Merck Veterinary Manual describes otitis externa as inflammation of that outer canal, often set up by moisture, debris, allergies, and secondary yeast or bacterial overgrowth. Warmth plus trapped dampness does not guarantee infection, but in day-to-day practice it lowers the margin for error.
That is why I treat ear checks as maintenance for drop-eared dogs, not just sick-visit care.
Prevention supports comfort here more reliably than frequent deep cleaning does.
Which floppy-eared breeds tend to need the closest watch?
Individual dogs vary widely, even within one breed. Coat, swimming habits, allergies, and canal shape matter as much as ear length. Still, these are the types vets often see for repeat waxy buildup or head-shaking, and they help show what to plan for.
Scenthounds and heavy-eared companions
Basset Hound, Bloodhound, Coonhound types. Very long, low-hanging ears with heavy folds around the opening. Owners often notice a musty odor or brown wax first. Weight and neck skin can press the ear even tighter against the head.
Beagle. Shorter drop ears than a Basset, but the same covered opening. Many Beagles do well with simple visual checks, unless allergies or swimming enter the picture.
Spaniels and retrievers with feathered ears
Cocker Spaniel, English Springer Spaniel, Cavalier King Charles Spaniel. The American Kennel Club notes the long, well-feathered ears that define the Cocker Spaniel look, and that feathering can hold bath water and field debris near the canal. These breeds also have a higher background rate of allergic skin disease, which makes the canals itchier and waxier.
Labrador Retriever and Golden Retriever. Technically drop ears rather than very long hounds’ ears. Swimming is the usual trigger — a wet swim followed by a long nap without drying time.
Wrinkled and long-backed breeds
Shar-Pei, Bulldog types, Dachshund. Narrower canal openings or extra skin around the base can reduce ventilation further. They may not look as “floppy” as a Hound, yet the same check-and-dry logic applies.

What a steady home routine actually looks like
My evidence-bounded recommendation is this: look and sniff weekly, clean only when you see light wax or debris, and dry after water exposure.
That stance comes from preventive-care experience plus otitis guidelines — routine inspection catches redness early, while over-cleaning healthy ears can irritate them. The VCA Hospitals ear-cleaning guide makes a similar point: use a veterinarian-approved cleaner, avoid cotton swabs deep in the canal, and stop if the ear is painful, very red, or swollen.
The 60-second check I wish every owner did
Lift the flap in daylight. The skin should look pale pink, with little to no odor and only a thin film of light tan wax.
After swimming or a bath, gently blot the underside of the flap and around the opening with a soft towel. You can fan the ear open for a few minutes while your dog rests. That drying step matters more than buying a stronger cleaner.
For dogs that need regular bathing, choosing a gentle formula helps avoid added irritation around the ears and neck — see Best Dog Shampoo for Sensitive Skin: What Actually Matters on the Label for what to look for on the label.
Keep grooming calm and Fear Free: treats, short sessions, and no pinning the dog down to “get it over with.”
When to clean, and when to call the vet instead
Clean when you see mild waxy buildup in an otherwise comfortable ear, using a product your own vet has approved for your dog. Do not start a cleaning series when you see head-shaking, scratching that breaks skin, strong odor, dark discharge, swelling, pain when the ear is touched, or a head tilt.
Those signs point toward active otitis or a foreign body, and cleaning over them can hurt and obscure the exam. Vets often see drop-eared dogs whose owners cleaned diligently for two weeks while a yeast flare kept building — earlier exams would have shortened the course.
What would change my mind toward more frequent scheduled cleaning for every floppy-eared dog? A prospective study showing that routine weekly flushing lowers infection rates in healthy drop-eared dogs without increasing irritation. Current evidence does not show that, so I stay with check-first care.
Pair that habit with the rest of the body: teeth, nails, and coat condition often shift on the same schedule. Owners splitting tasks between home and clinic may find At-Home Grooming vs a Professional Groomer: How to Split the Job and How to Care for a Dog’s Teeth Without Brushing useful for building a realistic calendar.
Size changes how you handle the dog, not whether the ears need air. For positioning tips for small versus large dogs, see Grooming Needs by Dog Size: Small vs Large Breeds.
The bottom line for households choosing a drop-eared dog
Floppy ears are not a flaw to manage around. They are a trade-off: soft expression and breed type in exchange for less ventilation.
If your household swims often, hikes in tall grass, or prefers low-maintenance grooming, favor a breed with lighter, higher-set ears or plan for consistent drying time. If your heart is set on a Basset, Spaniel, or Hound, go in with eyes open and make the weekly lift-and-look part of cuddle time.
Individual dogs vary, and your own vet can tailor the plan to your dog’s canals, skin, and allergy history.
Frequently asked questions
Do all dogs with floppy ears get ear infections?
No. Drop ears trap warm air and slow drying, which can support yeast and bacterial overgrowth, but many floppy-eared dogs stay healthy with simple checks, drying after swimming or baths, and prompt vet care for itching or odor. Allergies and swimming habits matter as much as ear shape.
How often should I check a drop-eared dog's ears?
A weekly lift-and-look works for most dogs: check for pale pink skin, light wax only, and no strong odor, head-shaking, or pain. Clean only when you see light debris and your vet has approved a cleaner, and ask your vet for a personal schedule if your dog swims often or has allergies.
Can I use cotton swabs to clean deep inside the ear?
No. Swabs can pack debris deeper and injure the canal, especially in the L-shaped dog ear. Blot outer folds with a soft cloth, use only a vet-approved cleaner as directed, and schedule an exam for redness, swelling, discharge, odor, or pain.
