Visual Signs of Dog Ear Infections
When examining your dog's ears for infection, several distinctive visual indicators should catch your attention:
Ear Canal Appearance
- Redness and inflammation inside the ear canal
- Visible swelling that may partially close the ear canal
- Dark brown or black discharge resembling coffee grounds
- Yellow or greenish pus-like secretions
- Waxy buildup that appears excessive or abnormal
External Ear Changes
- Crusty or scaly skin around the ear opening
- Hair loss near or inside the ear
- Visible scratches or sores from excessive pawing
- Thickening or hardening of the ear flap
- Unusual ear positioning (drooping or stiffness)
Behavioral Symptoms Accompanying Visual Signs
Along with visible changes, dogs with ear infections typically display specific behaviors that confirm something isn't right:
Common Behavioral Indicators
- Frequent head shaking or tilting
- Persistent scratching at ears
- Rubbing ears against furniture or floor
- Showing pain when ears are touched
- Increased irritability or restlessness
Types of Ear Infections and Their Appearance
Bacterial Infections
Bacterial infections often present with yellowish-green discharge and a strong, unpleasant odor. The ear canal typically appears red and inflamed, and the discharge may be thick or puslike.
Yeast Infections
Yeast infections usually produce a dark brown or black discharge with a distinct sweet or musty smell, often described as similar to bread dough or corn chips. The ear canal may appear more pink or red than normal.
Ear Mite Infections
Ear mite infections create a characteristic dark, coffee ground-like discharge. The debris appears dry and crumbly, and you might notice tiny white spots moving within the ear canal.
When to Seek Veterinary Care
Certain visual signs warrant immediate veterinary attention:
- Blood or extremely dark discharge
- Completely closed ear canal due to swelling
- Signs of trauma or injury to the ear
- Balance issues or unusual eye movements
- Severe pain or aggressive response to ear touching
Prevention and Monitoring
Regular ear checks can help you catch infections early. Establish a routine of examining your dog's ears weekly, looking for:
- Changes in ear color
- Unusual odors
- Excessive wax buildup
- Signs of irritation or discomfort
- Abnormal discharge
