The L-shape of dog and cat ear canals are designed to protect their highly developed sense of hearing. Unfortunately, this design may also cause moisture, debris, parasites and wax to be trapped in the ears, resulting in infections.
Causes of Ear Infections
In cats, the most common causes of ear infections are mites or a weak immune system (which may be caused by the feline leukemia virus or feline immunodeficiency virus). Persian cats can be prone to ear infections.
In dogs, the most common underlying afflictions are allergies (upwards of 80%) and yeast, both of which often result in secondary bacterial infections. Dogs with floppy ears and swimmers are prone to ear infections.
Other causes of ear infections include:
- Fungal and yeast infections can result in scratching that turns into a bacterial ear infection.
- Inherited anatomical abnormalities in the ear canal structure can leave pets predisposed to ear infections due to inadequate drainage or constriction.
- Chronic ear infections can cause a build-up of scar tissue, leading to more infections.
- Ear growths/tumors/polyps may block efficient ear drainage in both dogs and cats.
- Ticks and fleas
- Water in the ears after swimming or a bath may cause an ear infection in dogs.
- Hot, humid weather brings a higher risk of infection.
- Trauma to the ear
- Hormonal imbalances
Symptoms of an ear infection may include:
- Excessive ear scratching or rubbing ears against objects
- Head shaking or tilting
- Foul smell that may remind you of yeast, sweat socks or a sewer
- Redness & bleeding
- Matted fur around the ears
- Stumbling, walking in circles, clumsiness
- Droopy eyes
- Brown, black or yellow discharge
- Pinkish-brown ear wax may indicate a yeast infection
- Dry, dark, discharge may be ear mites, which can lead to an ear infection.
Preventing & Treating Ear Infections in Dogs & Cats
High quality essential oils may be blended into a cleansing and/or natural treatment solution for ear infections, with the most commonly used for dogs being lavender, aloe vera, mullein flower, grapefruit seed extract, bergamot, niaouli, calendula, manuka and chamomile. Cats are highly sensitive to essential oils but some are reputed to be safe to use as hydrosols, such as witch hazel, aloe vera, rose, and lavender.
Remember to use very small, heavily-diluted amounts of essential oils for all pets. We rely on essential oils from Starwest Botanicals for their medicinal quality. Avoid drying agents like alcohol and dangerous “cures” like gentian violet. If you prefer a premixed solution, holistic veterinarians often recommend Ear Clean.
Medications are often necessary to bring an ear infection under control, especially if the problem is in the inner ear or if serious swelling is involved. Unfortunately, a vicious cycle can follow treatment with antibiotics, anti-fungal medications and other drugs intended to treat ear infections in dogs and cats. The chemical balance of the ear and the bacterial balance within the body is often affected by these treatments, resulting in a long-term battle against secondary and recurring infections. Antibiotics, for example, can inadvertently kill off beneficial bacteria, allowing yeast to flourish.
It is very important to nurture balance following medication, and maintaining that balance should become a routine part of natural pet care to prevent ear infections and mites.
This may include:
- Prebiotics and probiotics (such as plain yogurt)
- Cleaning with white or apple cider vinegar to maintain a healthy chemical balance in the ear
- Feeding anti-fungal foods
- Feeding anti-inflammatory foods
- Nurturing a healthy immune system with a naturally balanced diet that includes antioxidants and fatty acids.
Cleaning dog and cat ears every 1-3 weeks can prevent infections. This can be as simple as a 1:1 blend of organic apple cider vinegar or white vinegar with sterile water. Some holistic veterinarians also suggest making a pure, green tea that can be cooled and dropped into the ear. A convenient option is purchasing natural ear cleansing solutions or mite treatments. Cleaning ears too often can cause problems of its own, so only clean when necessary.
Use a soft plastic dropper and massage the base of the ear to distribute. When your dog or cat shakes their head afterward, the debris will be ejected. Clean around the ears and dry thoroughly with a clean cloth. Do not use cotton swabs. Note: If massaging the ear causes pain, it may be due to a foreign object in the canal or severe infection. Stop massaging and contact your Veterinarian.
Keep ear hair clipped if your dog or cat has a lot of fur in the ear. This allows for more air circulation. Be sure to use blunt-tipped scissors or an electric trimmer.
If you suspect allergies, try a gradual switch to a more natural food that doesn’t contain harsh chemicals, and a short ingredient list that allows for a process of elimination. You may also wish to try quercetin or bromelain supplements, which may help prevent allergic reactions in the gastrointestinal tract. They can often be found in combined formulations for easy administration. Environmental allergies may include pollen or dust mites.
If ear mites are the issue, you can place a few drops of extra virgin olive oil or almond oil mixed with vitamin E into the ear after cleaning to smother them. Some also suggest following this treatment with a Yellow Dock infusion.
Note of Caution: Treatment of ear infections (otitis externa, otitis media and otitis interna) in dogs and cats should always begin with an examination and diagnosis by your Veterinarian. Your pet may initially require ear drainage or antibiotics. All natural treatments and dietary changes should be cleared by your Veterinarian.
