The ear canal is basically an extension of the skin and is prone to infection.
Ear infection can be caused by bacteria, yeast, or mites (small bugs)
Prolonged ear infections can lead to rupture of the eardrum and infection of the inner ear
Pets can also rupture a blood vessel in the ear when they flap the ears due to an ear infection. The ear swells up and forms what is referred to as an ear hematoma.
What Does It Look Like?
Ear infections often present as a dark discharge from the ears.
This can cause them to shake their head and paw at their ears
What Do You Do?
Use a general ear cleaner to flush out the ears
Do NOT stick anything (ie Q-tips) down the ear canal - you can rupture the eardrum
Instead, flush the ears liberally twice a day and after baths/grooming
If the discharge persists or an ear hematoma develops, seek veterinary care.
