What causes ear infections?


There are many reasons why our pet’s ears become inflamed.  Here are a few commonly seen causes.


Allergies : There is a strong link between allergic skin disease and Otitis (ear inflammation) and often an ear infection is the first symptom of underlying skin disease. 


Foreign bodies - Grass seeds can get stuck in your pet’s ear and cause pain and inflammation making the ear sore and irritating to your pet


Humidity - Moisture in your pet’s ears encourages yeast and bacteria to grow.


Narrowed ear canals – some breeds of dogs eg the Shar Pei, have narrowed ear canals making drainage from the ear, and good ventilation into the ear canal difficult. For these breeds of dogs getting ear treatment into the right part of the canal to get a quick resolution can be tricky. 


Parasites - Mites are often a cause of ear infection in young animals. These pets are highly irritated by their ears, and often have a dark brown discharge from the ears.  


What to do if you think your pet has an ear infection. 

Make an appointment at your local vet clinic. The vet will examine your cat or dog from top to toe including a focus on the ear canals.  They will use an otoscope to look into the ear canal and take swabs to analyse what type of infection is present. Often if we can’t see right down the ear canal because it is either painful or full of discharge we will suggest a small sedation procedure for your pet so we can clean the ear and examine the ear drum. We will then prescribe an appropriate medication for the ear, and can show you how best to apply this to the ear canal.


How you can prevent ear infection

Check your pet’s ears regularly and be on the look out for signs of an infection. If ears are not a healthy pink colour, if they have a discharge or odour, or if you notice swelling or pain from the ear then consult your veterinarian. Check your pet’s ears regularly and be on the lookout for signs of an infection. Also, regular cleaning by lifting the ear; squeezing in a recommended ear cleaning fluid; gently massaging the ear to distribute the fluid; and removing excess liquid with cotton wool can help with pets that are prone to infections, Your vet or vet nurse can show you how to properly clean your pets ears.


And finally, never use cotton buds in your pet’s ears as this could cause further damage to the ears.
