Ear infections are one of the most common health issues we see in pets. Ear infections can be due to many different reasons. Through accurate diagnosis we can get the correct treatment for your pet.

    Symptoms can vary but commonly you may notice:

  • Shaking of the head
  • Odour
  • Redness/discharge
  • Scratching/Rubbing at ears
  • Behavioural changes

One way we may diagnose an ear infection is via a cytology sample that we examine under the microscope. This will let us know exactly what type of infection your pet has so we can prescribe the right ear medication.

There are three main types of infective organisms we commonly see; ear mites, bacteria and yeast.


  • Ear Mites: Ear mites are often passed from pet to pet and are more common in young animals and those who spend a lot of time outdoors. They are barely detectable by the naked eye and can cause some serious ear and/or skin infections.
  • Bacteria: Bacteria are one of the most common causes of ear infections. Low numbers of bacteria are seen in the normal ear. Changes in the ear environment (moisture, heat, hair, foreign body) can lead to an overgrowth of bacteria and cause infection.
  • Yeast: This is also one of the most common causes of ear infections. Yeast is also found in the normal ear in low numbers. But like bacteria, changes in the ear environment can cause an overgrowth of yeast which will lead to an infection.


A combination of the above organisms can also be present causing a mixed infection.

The good news is that with proper diagnosis, ear infections can be treated and hopefully prevented with the right management plan for your pet.

It is a vital part of treating an ear infection that you make sure you follow the veterinarians instructions with medication and revisit appointments to ensure any infection has cleared up. Although you may notice an improvement in your dogs signs and appearance of the ear, this does not necessarily mean the infection has been cleared up. If there is any remaining organisms in the internal ear canal and treatment has stopped prematurely, the ear infection will likely return.

If you would like to know more or are concerned your pet may have an issues with their ears, please do not hesitate to call the clinic to speak to one of our helpful staff on 9398 3333.
