Ear infections are one of the most common (and uncomfortable) conditions we see in dogs — and yes, cats too. While they can happen at any time of year, we often see an increase in ear infections during warmer months, especially in pets who love swimming or spending time outdoors.
Understanding why ear infections happen, what signs to look out for, and when to seek veterinary care can help keep your pet comfortable and prevent minor issues from turning into painful, ongoing problems.
Why Are Ear Infections More Common in Warm Weather?
Warm weather creates the perfect environment for ear infections to develop. Heat and moisture allow bacteria and yeast — which are normally present in small amounts — to overgrow inside the ear canal.
Common summer triggers include:
- Swimming or frequent bathing, where moisture becomes trapped in the ear
- Humidity and heat, which promote bacterial and yeast growth
- Floppy ears or hairy ear canals, which reduce airflow
- Underlying allergies, which can flare seasonally
Dogs that love the beach, lake or backyard hose are particularly prone, but any pet can be affected.
Signs Your Pet May Have an Ear Infection
Ear infections are uncomfortable and often itchy or painful. Common signs include:
- Head shaking or tilting
- Scratching or rubbing at the ears
- Redness or swelling of the ear flap
- Unpleasant smell coming from the ear
- Discharge (brown, yellow, or black)
- Sensitivity when the ear is touched
In cats, signs can be more subtle — scratching, crusting around the ears, or changes in behaviour may be the first clue.
Why Early Treatment Matters
Left untreated, ear infections can become more severe and harder to manage. Chronic infections may lead to:
- Ongoing pain and irritation
- Thickening and narrowing of the ear canal
- Ruptured eardrums
- Recurrent infections that require long-term management
Early treatment is usually simpler, more effective, and more comfortable for your pet.
Can I Treat My Pet’s Ear Infection at Home?
While it’s tempting to try home remedies or leftover ear drops, not all ear infections are the same. Some are caused by bacteria, others by yeast, parasites, or underlying allergies — and using the wrong treatment can make things worse.
A proper ear examination allows us to:
- Identify the cause of the infection
- Check the eardrum is intact
- Prescribe the correct treatment
- Address any underlying issues contributing to recurrence
How Can I Help Prevent Ear Infections?
While not all ear infections are preventable, these steps can help reduce risk:
- Gently dry ears after swimming or bathing
- Check ears regularly for redness or smell
- Only use ear cleaners recommended by your vet
- Avoid over-cleaning (this can irritate the ear)
- Seek early advice if you notice changes
If your pet is prone to recurring ear infections, we can help create a tailored prevention plan.
When Should I Book a Vet Visit?
If your pet is showing signs of discomfort, head shaking, or ear discharge, it’s best to book an appointment sooner rather than later. Ear infections are uncomfortable — and your pet will feel much better once treatment starts.
