3 Types Of Ear Infections In Dogs

Feb 25, 2025 | Pet Health, Pets

Happy Wednesday, everyone!  Did you know there are 3 Types Of Ear Infections In Dogs?  Jake and Maggie are prone to ear inflammation, so I’m always checking for inflamed ears that could possibly lead to an infection.  Once I see inflammation, I clean their ears with No Paws Cleaning Finger Wipes, squirt some Mal-A-Ket Plus (HERE), rub the ear and ear canal, and we are good to go.  It rarely leads to an infection.  But I never knew there are three types of ear infections until I read the Proud Dog Mom Blog.  I found this so interesting and had to share.

Before we get into ear infections, I have something exciting to talk about.  I signed up for a fundraiser to support our rescue pets at my friend’s brewery.  She is an amazing dog mom who supports pet rescue and has fostered many helpless dogs, helping to save their lives and finding them loving homes!  There will be a craft event to support Heart Of Glass Animal Rescue, and I will have a vendor table!  If you are in the area and want to join in the fun, come check us out.  I will talk more about this later and confirm the event’s time then.

Heart Of Glass’ mission is to rescue, rehabilitate, and re-home animals, including special needs, elderly, and behaviorally challenged dogs and cats.  They strive to provide a safe and loving space for animals in need while enlightening the community about proper animal welfare.

3 Types of Ear Infections

Dogs have three types of ear infections:

Otitis externa: inflammation of the ear canal

Otitis media: inflammation of the middle ear

Otitis interna: inflammation of the inner ear

Otitis externa is the most common dog ear infection, as this part of the ear is most exposed to the outside world. Ear infections can be acute (quick onset) or chronic (recurrent).

What Causes An Ear Infection?

Bacteria

Yeast

Wax buildup

Moisture in the ear

Excess hair

Allergies – both environmental and food

Ear mites and fleas

What’s the Difference Between a Dog Yeast Ear Infection vs. Bacterial Infection?

A yeast infection and a bacterial infection in dogs can look the same to the naked eye.  Your veterinarian can take a sample of the ear discharge to determine the difference. When examined under the microscope, your vet can distinguish between a bacterial and yeast ear infection by the microbes they see.

Yeast ear infections tend to have a distinct odor and have a darker brown discharge. Bacterial ear infections are usually a lighter brown or yellow color. Most dogs have a yeast infection when they have an otitis externa. Infections of the middle and inner ear are usually bacterial.

Know Your Dog’s Risk

While any dog can develop an ear infection, some breeds are more susceptible than others. Floppy ear dogs (such as Poodles, Labs, Hounds, Beagles, Spaniels, etc…) top the list. Having that enclosed ear canal creates a perfect moist environment for bacterial and yeast growth. Plus, floppy ears help to trap dirt, debris, and wax buildup.

Tips To Prevent An Ear Infection

1. Keep Your Dog’s Ears Dry

Moisture is the perfect breeding ground for bacteria. While you certainly don’t need to stop your water-loving pooch from taking a dip in the pool on a hot summer day, it’s important to dry her ears afterward. The same thing goes for bath time! Use either a cotton wipe or a piece of gauze to gently dry the ear flap and around the opening of your dog’s ear canal after exposure to water.

2. Pluck Excess Hair 

Have a breed where hair grows inside the ear (like poodles)? Then make sure to pluck it! If not, that excess hair in the outer ear canal will act as a trap for debris and moisture. And you know what that can lead to … infection!

This fine hair is usually easy to pull out with your fingers. But, you can also use a little ear powder and a hemostat. Important Note: Don’t stick the hemostat down into the ear canal because you can cause more harm than good. Just grab the hairs that you can easily see.  Think of it like tweezing your eyebrows – grab onto a hair with your hemostat and pluck.

3. Gently Clean Your Dogs Ears Regularly

Use these steps as your guide:

Use a soft cotton wipe, cotton ball, or cloth.

Dampen the wipe with an ear-cleaning solution (do not spray directly in the ear).

Using your index finger and the wipe, gently wipe away ear wax build-ups.

Get into every little crevice, cleaning out all the wax.

Do not push your finger too deep into the ear, as you may cause damage to the eardrum. Just focus on the surface level of wax.

Finish with a dry cotton wipe to dab away any leftover moisture gently.

 
4. Feed A Healthy Diet 
 
According to the American Kennel Club: “About half of dogs with allergic skin disease and 80 percent of dogs with food sensitivities will develop ear inflammation.”
 
 
5. Monitor Your Pup’s Ears Regularly
 
Ideally, your furry friend’s ears should look smooth without any sign of irritation or swelling. They should feel dry and also be free of debris. While a slight yeasty smell can be normal (routine ear checks will help you know what’s normal for your dog), it should never be overpowering. If you notice anything otherwise, it’s best to take your pup to the vet for an ear check.
