Home Remedies for Ear Infections in Dogs

Ear infections are a common and persistent canine problem, and the majority of dogs will suffer from the unpleasant condition at some point or another. Any dog could potentially experience ear trouble, but long-haired breeds with excessive hair and upright outer ears are especially susceptible to canine ear infections. Unlike in humans, the ear canal in most dogs is typically vertical. This allows for a buildup of moisture and debris to become lodged in the ear, which can cause an infection. Depending on how extreme the ear infection is, signs cans range anywhere from non-existent to severe on the symptom scale. Ear problems are one of the biggest reasons dogs frequent the vet’s office. Though there are many pharmaceutical and home remedies for ear infections in dogs, the problem can recur often and be difficult to clear up.

What is an Ear Infection?

Ear infections can be extremely uncomfortable. They generally occur in dogs when either a viral or bacterial infection affects the area around and/or inside the ear. Dogs are susceptible to three types of ear infections:

  • otitis media– an inflammation in the area located directly behind the eardrum, more commonly referred to as the “middle ear”
  • otitis interna- swelling/inflammation of the inner ear
  • otitis externa– infected outer ear

The inflammation and build-up of fluids associated with ear infections can cause various levels of pain and discomfort in dogs. Irreparable damage to the middle and/or inner ear can occur in more severe cases where the infections have become chronic or incessant.

What are the Symptoms?

Symptoms of an ear infection can manifest both physically and behaviorally, and they should always be checked by a veterinarian. Physical signs of ear infections in dogs are:

  • Odor and/or discharge of ear- often yellow, brown, or even bloody in color
  • Redness/swelling
  • Scabbing/hair loss inside and around the outer ear
  • Impaired hearing/deafness

Behavioral signs of ear infections in dogs include:

  • Excessive scratching/rubbing affected on surrounding areas
  • Resisting to chew – they may stop playing with their chew toys
  • Head shaking/tilt
  • Loss of balance/altered sense of equilibrium
  • Uncharacteristic eye and body movements

What Causes Ear Infections in Dogs?


Bacteria is the leading cause of ear inflammation and infection in dogs. The dark, wet environment of the ear canal creates an ideal atmosphere for growing bacteria, which eventually increases to an elevated number where infection occurs.


Yeast is another primary cause of ear infections in dogs and can increase the chances of a bacterial infection. It easily grows in the moist conditions of the ear canal, and even certain dog foods (such as those containing a lot of refined carbohydrates) contribute to high levels of yeast production that can cause inflamed ears.


Dogs that struggle with environmental or food allergies will most likely suffer from ear infections. Allergies cause inflammation in the skin and can lead to the overproduction of yeast and bacteria: two very common triggers for ear infections in dogs.

Wax Buildup

Because the canine ear canal sits upright and has an “L”-shaped kink to it, wax and other potentially dangerous fluids can become trapped inside. This makes dogs naturally susceptible to ear infections. In particular, dogs with longer ears and excessive ear hair have an even greater tendency for waxy buildup, discharge, and infection.


Dogs who are active unknowingly pick up a ton of foreign objects just from adventuring outdoors. These foreign bodies, which include dirt and plant matter, often attach themselves to a dog’s collar or harness and eventually make their way to the ear, causing irritation and subsequent infection.

Ear mites

Ear mites are external parasites. They are more common in puppies as opposed to older dogs. Ear mites often cause hypersensitivity, which can result in intense itching and eventual irritation of the skin surrounding the ear canal.

Certain hormones, such as those produced by the thyroid and adrenal glands, influence the overall health of skin and ears. Therefore either deficiencies or excesses of these particular hormones can result in ear problems, including infections, for dogs

Swimmer’s Ear

Swimming allows moisture to enter the ear. This moisture, along with the vertical shape of the canine ear canal, promotes the growth of inflammation-causing microorganisms inside the ears of many dogs who love to swim.

How are Ear Infections Normally Treated?

Most commonly, ear infections in dogs require a thorough cleaning and/or a number of medications and can usually be treated with:

  • Ear-flushing– As the affected area is sensitive, cleaning an infected ear should be done using only the gentlest of cleansers and sterile cotton balls. Flush the ear as many times as the dog will allow comfortably, until the canal appears clean upon examination. Stay away from products like generic cotton swabs and rubbing alcohol, which can further irritate the present infection. Allow 10 minutes of drying time after ear-flushing.
  • Antibiotics– Either topical (ear drops/ointment) or oral (anti-inflammatory/pain relief medication). Be sure to complete the full course of antibiotics prescribed by the vet.
  • Steroids– Prescribed by the veterinarian to help ease inflammation and swelling.

Causes of Repeated Ear Infections

Chronic ear infections can lead to irreversible damage to a dog’s middle and/or inner and are often caused by:

  • Poor diet/allergies: Certain foods produce a lot of yeast, which is the most common cause of ear infections in dogs. Dogs with allergies and food aversions can develop inflammation, and healthy diets should be established early on.
  • Toxins: Discharge and inflammation are two signs of excess toxins. Regular vet checkups should be scheduled in order to monitor health.
  • Over-vaccination: Many ear infections are caused by immune system problems from vaccines. Do not over-vaccinate, and be aware of any unusual reactions.
  • Drugs: Medications can make the problem worse, and many dogs eventually develop a resistance. There are many other natural and home remedies for ear infections in dogs as alternative means of treatment.
