Here's a breakdown of what it is and why it's important:
* Cerumen is a mixture of:
* Oil (sebum) produced by the skin: This helps keep the ears lubricated.
* Dead skin cells: These naturally shed from the ear canal.
* Earwax glands secretions: These contribute to the sticky nature of the earwax.
* Cerumen's purpose:
* Protects the ear canal: It traps dust, dirt, and other foreign objects from getting further into the ear.
* Keeps the ear canal clean: It helps remove debris and keeps the ear canal lubricated.
* Has antimicrobial properties: Cerumen helps fight off infections.
When cerumen becomes a problem:
While cerumen is normal, excessive buildup can lead to problems, such as:
* Ear infections: Cerumen can trap moisture, creating a breeding ground for bacteria.
* Hearing loss: A buildup of cerumen can block the sound waves from reaching the eardrum.
* Itching and discomfort: Excessive cerumen can cause irritation and scratching.
What to do about excessive cerumen:
* Regular ear cleaning: Clean your dog's ears regularly with a dog-safe ear cleaner. Never use cotton swabs, as this can push the cerumen further down the ear canal.
* Professional cleaning: If you notice excessive buildup, take your dog to the vet for professional cleaning.
It's important to note:
* If you see any signs of ear infection, such as redness, swelling, discharge, or shaking the head, take your dog to the vet immediately.
* Always use dog-specific ear cleaners, as human ear cleaners can irritate your dog's ears.
Remember, a little bit of brown wax in your dog's ears is perfectly normal and even helpful. However, if you notice any excessive buildup or signs of infection, it's best to consult with your veterinarian.
