What is an ear infection in dogs?
An ear infection in dogs (otitis) is an inflammation in the outer, middle, or inner ear. The external ear canal is most commonly affected – this is called otitis externa. It occurs repeatedly in many dogs and is one of the most common reasons for a vet visit.
A dog ear infection is not only uncomfortable and painful, but if left untreated, it can also become chronic and, in the worst case, even damage hearing. It is therefore all the more important that you recognize the first signs early and react correctly.
How do I recognize an ear infection in dogs?
The earlier you recognize an ear infection in dogs, the faster your coatry friend can be helped. The symptoms vary in severity depending on the stage.
Stage 1: Early signs of an ear infection in dogs
- Slight warming of the ears
- Increased scratching or rubbing of the ears on coatniture or the floor
- Slight change in ear odor, sometimes no visible discharge yet
Stage 2: Advanced ear infection in dogs
- Blackish-brown, foul-smelling discharge in the ear canal
- Significantly increased head shaking and visible discomfort
- Occasionally occurring pain, the dog withdraws or no longer allows its ear to be touched
Stage 3: Severe ear infection in dogs
- Purulent or bloody discharge from the ear
- Severe pain with excessive head shaking and scratching
- Frequent head tilting – an indication of a deeper infection or involvement of the inner ear
Stage 4: Chronic ear problems
- Thickening and tumor-like changes in the ear canal area
- Permanent narrowing of the ear canal, which makes healing significantly more difficult
At the latest from stage 2, you should definitely have an ear infection in dogs checked by a veterinarian. The longer you wait, the greater the risk of a chronic ear infection.
What helps with ear infection in dogs? Treatment and Therapy
The correct treatment of an ear infection in dogs depends on the cause and severity. Your veterinarian will examine the ear, inspect the ear canal, and if necessary, take swabs to identify bacteria, yeasts, or mites.
- Cleaning the ears: Regular, gentle cleaning with a suitable ear cleaner for dogs can help remove excess discharge, dirt, and germs.
- Medication: Depending on the findings, ear drops with anti-inflammatory, antibacterial, or antifungal agents may be necessary. For mite infestation, special products are used.
- Pain relief: If your dog is in severe pain, the vet may also prescribe painkillers or anti-inflammatory drugs.
- Treatment of the underlying disease: In cases of allergies, kidney problems, or hormonal disorders, the underlying cause must also be treated – otherwise, the ear infection in dogs will keep returning.
Important: Please never use human medications on your own and do not experiment with only home remedies for ear infections in dogs in deeper stages. These can provide support, but they do not replace a diagnosis and therapy from the vet.
Home remedies for ear infections in dogs – what is allowed?
Many owners look for ear infection in dogs home remedies to gently support the ear canal. Gentle measures can sometimes provide relief in early stages – but only as long as there are no purulent, bloody, or extremely painful findings.
What you should consider:
- Some home remedies that are common in humans can cause great damage in a dog's ear.
- Oils, alcohol, or vinegar solutions do not belong in the ear without veterinary recommendation.
- Only use products that are explicitly intended for dog ears – if in doubt, always consult your veterinarian.
However, you can generally support your dog by:
- ensuring an allergen-poor, high-quality diet
- strengthening its immune system through the gut (e.g., with functional toppings)
- gently removing moisture from the ears after swimming
Which dogs are prone to ear infections?
Certain breeds are particularly susceptible to ear infections in dogs. Especially dogs with droopy ears or dense hair in the ear canal have a higher risk because the ear environment remains moist and warm – an ideal breeding ground for bacteria and yeasts.
- Cocker Spaniel
- Poodle and Schnauzer
- Bernese Mountain Dog and Newfoundland
- Retriever and Spaniel breeds
For these dogs, regular ear checks should be part of your routine. This way, you can usually detect a developing dog ear infection early.
Chronic ear infection in dogs
If an ear infection in dogs does not heal completely or constantly recurs, it is called a chronic ear infection. The tissue in the ear then changes permanently:
- the ear canal thickens
- proliferative changes form
- the ventilation of the ear becomes progressively worse
In such cases, simple treatment with drops is often no longer sufficient. Sometimes long-term therapies or even surgical interventions are necessary to permanently relieve your pet. This makes early treatment of every ear infection in dogs all the more important.
How long does an ear infection in dogs last?
An uncomplicated, acute ear infection can significantly improve with the right treatment within a few days to two weeks. It is important to complete the therapy as prescribed by the veterinarian – even if your dog seems fit again sooner.
Chronic ear infections, on the other hand, can drag on for months and often require a combination of:
- consistent ear care
- medication
- dietary adjustments (e.g., for allergies)
- treatment of underlying diseases (kidney, skin, hormones)
Causes of ear infection in dogs
The causes of an ear infection in dogs are diverse and range from anatomical peculiarities to allergies and internal diseases.
Kidney dysfunction
In traditional Chinese veterinary medicine, there is a close connection between the ears and kidney function. Dogs with chronic ear problems often also show abnormalities in the kidney area. It is therefore worthwhile to have organ values checked for recurring ear infections in dogs.
Allergies as a cause
Many allergies manifest as recurring inflammations of the skin and ears. An ear infection in dogs can therefore be an important warning sign that your dog is reacting to food components, pollen, mites, or other environmental factors.
An allergen-poor, easily digestible diet is an important component here. Especially the gut plays a crucial role as the seat of a large part of the immune system.
How can I prevent an ear infection in dogs?
You can do a lot to reduce the risk of an ear infection in dogs:
- Regularly check ears – especially after swimming or rain
- Gently dry moisture in the ear without going into the ear canal with cotton swabs
- For susceptible breeds: regular, gentle cleaning as recommended by the veterinarian
- Have allergies checked if the dog ear infection recurs
- Support the immune system – e.g., through a gut-friendly, functional diet
When do I need to take my dog to the vet?
You should always have an ear infection in dogs checked by a vet if:
- there is a strong odor or purulent discharge from the ear
- your dog is in pain and no longer allows its head to be touched
- it tilts its head or shows balance disorders
- the symptoms do not improve within a few days despite care or ear cleaner
- the ear infection in dogs keeps recurring
Home remedies can support therapy, but they never replace a thorough diagnosis. An untreated ear infection in dogs can lead to chronic pain and hearing loss in the long run.
