Dog & Cat Ear Infections: Signs, Causes & Treatment

    pet ear infections

Uh-oh! You notice that your pet’s ears are hot, red, smelly or stinky and with an unusual discharge. These signs can be worrisome for any pet parent, but don’t panic—understanding the common symptoms and causes of ear infections in your dog or cat can help you act fast and keep your pet comfortable.

What causes ear infections in dogs or cats?

Understanding the cause of ear infections in your pet can help prevent future episodes. The following are the most common causes of your pet’s ear woes:

Moisture

Moisture is a common culprit. Dogs who swim frequently or have droopy ears, like cocker spaniels, can get water trapped in their ears, creating a perfect environment for bacteria and yeast to grow.

Allergies

Allergies can play a significant role in ear infections. If your dog suffers from food, environmental or flea allergies, their ears may become inflamed more easily. 

Foreign bodies

Foreign bodies such as grass awns (foxtails) can cause irritation if they get lodged in your pet’s ears.

Ear mites

Mites are a common parasite in dogs—and in outdoor cats and newly adopted kittens, too. They cause extreme itching and pain, and are a common cause of ear infections.

Hormone imbalance

An imbalance in certain hormones, like thyroid hormone, can predispose a pet to infections, including ear infections. Other symptoms, such as changes in energy, appetite, thirst and urination, usually accompany thyroid hormone issues. 

By identifying these triggers, you can work with your veterinarian to minimize exposure and implement effective prevention strategies. 

Does my dog have an ear infection?

If you're wondering if your dog has an ear infection, take a close look at their ears. Typical signs of a dog ear infection include redness, swelling, a foul odor and an accumulation of wax or discharge (often black or white). Your dog might also scratch at their ears or shake their head frequently. These symptoms signal that it’s time for a veterinary visit. Once diagnosed, your veterinarian will guide you on the best dog ear infection treatment to get your pup back to their happy self.

Does my cat have an ear infection?

If you’re wondering if your cat has an ear infection, look for similar signs: redness, an unpleasant smell and unusual discharge. The signs of a cat ear infection might also be subtle—slight swelling or a dark, crusty build-up in the ear canal. Cats may also exhibit head shaking or ear scratching, but sometimes they hide these symptoms better than dogs. Because cats are masters of hiding discomfort, any change in behavior, like reduced grooming or increased irritability, should prompt a closer look. If you spot these clues, consult your veterinarian promptly for a proper treatment plan.

Once a diagnosis is confirmed, dog or cat ear infection treatments typically involves gentle cleaning and medication to clear up the infection. Avoid using over-the-counter remedies without veterinary guidance, as improper care can worsen the condition.
