7 Dog Breeds Most Prone to Ear Infections

Dan noticed it during towel-off time. Gabby, his 7-year-old spayed female German Shorthaired Pointer mix, kept shaking her head after a swim in West Palm Beach, and one ear smelled faintly sweet after three days of humid Florida air.

Vets often see versions of that moment, especially in summer. A dog with long, hanging ears swims or bathes, moisture lingers in the canal, and head-shaking starts a few days later. That pattern is why ear shape and coat deserve as much attention as any cleaner or home remedy.

Ear infections in dogs, usually otitis externa, mean inflammation of the outer ear canal, often with yeast or bacteria involved. According to VCA Hospitals, warm, poorly ventilated canals and underlying allergies create conditions where microbes can overgrow. The Merck Veterinary Manual notes similar predisposing factors, including ear conformation, moisture, and hair in the canal.

Why do some ears trap more trouble than others?

Think of the canal as a hallway that needs airflow. Floppy pinnae lay a blanket over the opening. Long, hairy canals add surface area and trap wax. Dogs that swim weekly or live in humid climates stay damp longer.

That does not guarantee infection. Individual dogs vary widely, even within a breed. But less airflow plus more moisture means less margin for error, which is why checks matter more for some shapes than others.

Which breeds should owners watch most closely?

No list is absolute, and mixed-breed dogs like Gabby can be just as affected. With that caution, vets tend to watch these types more closely because of anatomy, coat, or allergy risk:

1. Cocker Spaniel — long, heavy ears and a hairy canal.
2. Basset Hound — very long pinnae that limit airflow.
3. Labrador Retriever and Golden Retriever — love water, plus allergy risk.
4. Shar-Pei — narrow canals and skin-fold tendencies.
5. Poodle and Poodle mixes — hair growth in the canal.
6. Bulldogs and Pugs — skin folds, allergies, and narrow openings; Leonardo, a 3-year-old intact male Pug mix in Oakland, is the kind of dog whose owner, Jesus, may notice rubbing and brown waxy buildup within 2 weeks of allergy season.
7. German Shepherd Dog — upright ears, but allergy-related inflammation still brings repeat flare-ups.

Short ears are not a free pass.

Allergies, swimming, and wax buildup can affect any dog. The takeaway is risk, not destiny.

What does a puppyhood ear-check routine actually look like?

Start young, keep it calm, and pair it with something the dog already likes, such as brushing or a bath towel routine. The goal is familiarity, not deep cleaning every time.

Once a week, lift each flap in good light. Look for odor, redness, swelling, dark discharge, or pain when touched. Note what normal looks like for your dog so change stands out. After swimming or bathing, gently dry the outer ear with a soft towel and let air circulate.

Keep tools simple and dog-friendly. A basic kit described in Essential Dog Grooming Tools for Beginners supports regular handling without turning it into a wrestling match. If you already split chores between home and salon, the approach in At-Home Grooming vs a Professional Groomer: How to Split the Job may help maintain a steady schedule.

Skip cotton swabs in the canal, plucking large amounts of hair at home, or pouring in homemade mixes. Those steps often irritate tissue more than they help, and the evidence for prevention is thin.

When should grooming pause and a vet visit happen?

Grooming supports clean, dry, comfortable ears. It does not diagnose or treat infection.

Call your veterinarian promptly for strong odor, yellow-green or bloody discharge, marked redness or swelling, pain, head tilt, scratching that breaks skin, or shaking that lasts more than a day. Puppies, dogs with repeat episodes, and dogs already on allergy or skin care need earlier checks rather than another round of cleaning.

Bring notes: which ear, when signs started, recent swims or baths, new foods or treats, and any cleaner used. That history helps the vet decide whether cytology, allergy work, or a different maintenance plan fits.

For owners of floppy-eared breeds, routine checks from puppyhood are the highest-value habit. They take two minutes, build tolerance for handling, and catch small changes before they become painful infections.
