Greasy brown discharge with sweet musty smell (yeast Malassezia)? Yellow-green pus mixed with brown crust (bacterial)? Dry dark coffee-ground gunk (ear mites debris)? Or soft light brown wax (healthy)? Upload a close-up photo of your dog's ear — AI identifies the 4 most common causes of brown discharge dog ear infection. Triage urgency + typical US vet cost. ⚠️ Head tilt, balance loss, or walking in circles = same-day emergency — middle/inner ear involvement, skip the photo.

Good photos
Avoid
Gently fold back your dog's ear flap to expose the canal. Take a close-up of the brown discharge or gunk visible inside. Natural daylight, no flash (flash distorts discharge color). Photograph BEFORE cleaning — wiping the discharge loses the diagnostic visual pattern. If both ears have brown discharge, photograph each separately.
The AI compares your photo against 4 distinct brown discharge dog ear infection patterns: greasy brown smear with sweet smell (yeast Malassezia), yellow-green pus mixed with brown crust (bacterial), dry dark coffee-ground gunk (ear mites debris), and light brown soft wax (healthy excess wax). Texture, color, and odor signal are analyzed.
Receive the most likely cause of the brown discharge, urgency level (watch at home → emergency), typical US vet visit cost estimate, and what to prepare. AI is educational pattern recognition — not a veterinary diagnosis.
Brown discharge dog ear infection — match what you see to the most likely cause. Upload your dog's ear photo above for AI analysis that goes deeper than this table.
Light brown soft wax + no smell + dog acting normal + no scratching
Healthy excess ear wax accumulation — weekly cleaning, watch for change
Greasy brown discharge + sweet musty smell + persistent head shaking + scratching
Yeast infection (Malassezia) typical pattern — greasy texture + sweet smell signature
Thick black gunk in dog's ear + intense itching + dark crust around outer ear flap
Ear mites (Otodectes cynotis) debris — highly contagious; black gunk + intense itch signature
Yellow-green pus + brown crust + foul rotten smell + pain on touch + redness
Bacterial infection (often secondary on top of yeast or mites) — vet cytology + care plan needed
Brown discharge + head tilt + balance loss + walking in circles + facial droop
Middle/inner ear infection — emergency vet now; risk of permanent nerve damage
