Ears - how to prevent and treat infections and irritation

Avoid repeat flare up with this protocol to keep bacteria at bay.

French Bulldogs are notably predisposed to ear infections (otitis externa) due to their narrow ear canals, prominent upright pinnae (“bat ears”), and tendency toward allergic skin disease. Allergies, excessive moisture, and bacterial or yeast overgrowth are common underlying causes. Effective ear care in this breed focuses on routine cleaning, prevention of moisture buildup, early detection of inflammation, and veterinary-guided treatment where necessary.

​

Routine ear hygiene is an essential part of managing a French Bulldog’s ear health. Regular cleaning—typically once to twice weekly, or as directed by a veterinarian—helps remove wax, debris, and allergens that contribute to infection. A veterinary-recommended ear cleaner with drying, antiseptic, or anti-yeast properties should be used, depending on the dog’s specific needs. Commonly recommended products include Epi-Otic Advanced Ear Cleanser (Virbac), Otomize, MalAcetic Otic Cleanser (Dechra), or AuroEar Flush. For dogs prone to yeast infections, cleaners containing 2% acetic acid or boric acid (such as MalAcetic) help maintain an acidic environment that discourages yeast growth.

​

When cleaning, it is important to apply the solution generously into the ear canal, gently massage the base of the ear to loosen debris, and then allow the dog to shake its head. The outer ear and visible folds should be wiped clean with a soft cotton pad or gauze—never with cotton swabs, as these can push debris deeper into the canal or damage the eardrum. The ears should be thoroughly dried after swimming or bathing, as residual moisture can create a favourable environment for bacterial or fungal proliferation.

​

Monitoring for early signs of infection is critical. Redness, dark or odorous discharge, head shaking, pawing at the ears, or sensitivity to touch often indicate developing otitis and require veterinary attention. Chronic or recurrent infections may indicate underlying allergies or endocrine disorders, which should be addressed to achieve lasting control. Veterinarians may prescribe topical medications such as Otomax, Surolan, or Posatex, which combine antibiotic, antifungal, and anti-inflammatory ingredients, depending on the diagnostic findings from ear cytology.

​

Allergy management plays a key role in preventing recurrent ear disease. As with skin allergies, identifying and reducing exposure to allergens—through diet trials, omega-3 supplementation, or immunotherapy—can significantly decrease the frequency of ear flare-ups. Products such as Royal Canin Sensitivity Control or Hill’s Prescription Diet z/d are often beneficial for dogs with concurrent food sensitivities.

​

Maintaining an appropriate home environment also supports ear health. Regular cleaning of bedding, minimising dust and pollen exposure, and ensuring the home remains free from smoke and strong fragrances can help limit irritation. Owners should also avoid over-cleaning, as excessive ear flushing can strip protective oils and disrupt the natural balance of the ear canal.

​

With consistent maintenance, prompt response to early signs of infection, and careful management of contributing factors such as allergies or humidity, most French Bulldogs prone to ear infections can maintain healthy, comfortable ears. Regular veterinary examinations—ideally every three to six months—are recommended for dogs with a history of otitis to ensure the ear canals remain clean, open, and infection-free.
