Why Cornish Rex Ear Care Matters
Ear infections are one of the most common — and most preventable — grooming-related health issues in dogs. For the Cornish Rex, ear anatomy and coat type interact: tight curly hair inside the ear canal traps wax and moisture, blocking airflow and creating ideal conditions for infection. The Cornish Rex produces more skin oil than most cats because there are no guard hairs to distribute and absorb it — weekly ear cleaning and monthly bathing with a gentle shampoo keep the skin from becoming greasy. Left untreated, ear infections cause pain, head shaking that can rupture blood vessels in the ear flap (aural hematoma), and chronic scarring that narrows the canal permanently.
How Often to Clean Your Cornish Rex's Ears
Healthy Cornish Rex ears need cleaning every 1–2 weeks as part of routine maintenance — not daily, which strips protective wax and irritates the canal. Increase frequency to weekly during swimming season, after baths, or if your dog has a history of ear issues. Breeds with hair growing inside the ear canal, common in very short, ultra-fine, wavy, down-only, no guard hairs coats, may need professional ear plucking every every 6-8 weeks to keep the canal open — ask your groomer whether plucking or trimming is appropriate for your Cornish Rex. Never clean ears that look red, swollen, or smell strongly yeasty — those symptoms mean infection, and cleaning can push debris deeper. See your vet first.

Proper Ear Cleaning Technique
Use only a veterinarian-approved ear cleaner — never hydrogen peroxide, alcohol, or water alone, all of which irritate the sensitive canal lining. Fill the ear canal with cleaner until you see it pool at the opening, massage the base of the ear for 20–30 seconds (you'll hear a squelching sound — that's correct), then let your Cornish Rex shake their head vigorously. This shaking is essential — it brings dissolved wax and debris to the outer ear where you can wipe it away with cotton gauze or a soft cloth. Never insert cotton swabs into the canal; they push debris inward and can rupture the eardrum. Work in a bathroom or outdoors — the head shake sends fluid flying. Finish by drying the outer ear thoroughly; moisture left in the fold is a common infection trigger.
Signs of Ear Infection in Cornish Rexs
Know the difference between dirty ears and infected ears. Dirty ears have visible brown wax at the opening but no odor, redness, or behavioral change. Infected ears smell distinctly yeasty or foul, show redness or swelling inside the canal, produce dark discharge, and cause your Cornish Rex to scratch persistently, shake their head, or tilt it to one side. Any head tilt lasting more than a day, balance problems, or crying when the ear is touched requires same-day veterinary attention. Chronic infections in floppy-eared breeds often trace back to inconsistent cleaning or incomplete drying after water exposure — both are entirely preventable with a consistent routine.
Coat and Ear Hair Management
For the Cornish Rex's very short, ultra-fine, wavy, down-only, no guard hairs, hair inside and around the ear opening needs regular attention. Trim or pluck excess hair from the ear canal opening to improve airflow — your groomer can demonstrate the correct technique during your next every 6-8 weeks appointment. After every bath, place a cotton ball loosely in each ear during rinsing to prevent water entry, and remove it immediately after — never leave cotton in the ear. The Cornish Rex produces more skin oil than most cats because there are no guard hairs to distribute and absorb it — weekly ear cleaning and monthly bathing with a gentle shampoo keep the skin from becoming greasy. A light dusting of ear powder before plucking (if your groomer recommends plucking) gives grip and reduces discomfort.
Pro Tip from Groomas
Never use a slicker brush on a Cornish Rex — the down-only coat breaks very easily; use only your bare hands or a very soft chamois cloth to smooth the coat.
