What does ear scratching look like in dogs? How much is too much?
Dogs show ear irritation in a few different ways: scratching with a back paw, shaking their head, or rubbing their ears on the couch or carpet.
These behaviors once in a while are usually nothing to worry about. What matters is the pattern. If you're noticing these signs several times a day, or enough that it stands out as new or persistent, it may mean your dog’s ears are feeling irritated rather than just occasionally itchy.
That shift from an occasional scratch to a noticeable routine is often the first clue that something in the ear needs attention.
Why does my dog keep scratching their ear?
As a concerned dog parent, it’s natural to want to know exactly what is causing your dog’s itchy ears so you can help them feel better as soon as possible.
Constant itching can mean that your dog has an ear condition that requires a closer look, such as:
- Allergies, including reactions to fleas, food, or the environment
- An ear infection caused by bacteria or yeast
- Moisture buildup from swimming or bathing
- Ear mites (parasites) that can infect a dog’s ear canal
- A polyp (an abnormal growth) in the ear
- Excess hair in the ear
- Foreign material (like a grass seed) in the ear
If your dog is scratching often, your veterinarian can help sort through these and other possibilities and recommend treatment to help your dog feel more comfortable.
When should I contact a veterinarian about my dog’s ear-scratching?
Occasional ear itching can be normal and nothing to worry about. But if it becomes frequent, starts to interrupt your dog’s day, or comes with other changes, it may be a sign that their ears need attention.
Below are some common signs that suggest it may be time to get your dog’s ears checked:
- A sweet, musty, or corn-chip-like smell coming from your dog’s ears
- Itching more than a few times per day
- Scratching that keeps you up at night
- Yelping, nipping, or pulling away when you touch the ear
- Frequent head-shaking
- Redness, scabs, or swelling around the ears
- Brown or yellow debris inside the ears
- Matted hair around the ears
- Moist, irritated skin or hair loss around the ear
- Hearing loss—not listening to commands or looking confused about where a sound is coming from
If you’re seeing these signs along with ongoing scratching, scheduling a visit can help you understand what’s behind the irritation and how to help your dog feel more comfortable. Most of the signs above aren’t emergencies and many respond well to treatment, but it’s still recommended to have your vet take a look within a few days.
If your dog suddenly seems wobbly, is stumbling or tilting their head, or if their eyes move back and forth repeatedly, these can point to an inner ear or nervous system issue. These symptoms are more urgent and warrant an emergency visit.
How will my veterinarian treat my dog's ear scratching?
At your visit, your vet will start by taking a close look at your dog’s ears to understand what’s causing the scratching. They’ll begin with a full physical exam and may ask about your dog’s symptoms, recent changes, and anything else you’ve noticed at home.
Your vet may also run some tests, which may include:
- An ear swab and cytology: The vet will use a cotton-tipped swab to collect a small sample of debris from the ear canal. They will then check the sample to see if there are yeast, bacteria and/or mites present, as well as how severe the problem is.
- An ear culture: The vet will send the sample to a lab for testing to detect infection and identify the bacteria causing it, as well as what treatment may work best.
- Allergy testing or a food trial: Your dog might need blood or skin tests to check for environmental allergies. Your vet may also recommend trying a prescription diet to check for food allergies that could be causing your dog’s itchiness.
Some dogs with sensitive or painful ears may need medicine to stay calm and comfortable while the veterinary team collects ear swab samples and cleans and examines the ears.
If the cause is hard to find, your vet may suggest seeing a veterinary dermatologist, a doctor who focuses on skin and ear problems.
Final thoughts
Ear scratching can be uncomfortable for your dog and concerning for you to see. The good news is that you now know the common signs, what often causes them, and when it may be helpful to get your vet involved.
If the scratching is frequent or comes with other changes, your veterinarian can help figure out what’s behind it and recommend ways to bring your dog relief. And once you know the cause, your vet can also help you understand how to support your dog and reduce the chances of the problem returning.
Frequently asked questions
Frequently asked questions about this topic
Regular ear cleaning recommended by your veterinarian can help prevent itchiness in some dogs, but it may not fix itching that’s already happening. Cleaning sensitive ears with the wrong product or technique could make the issue worse. If your dog’s ears are itchy or painful, it’s best to check with your veterinarian before starting a new cleaning routine.
Any dog can develop itchy ears, but some dogs are more likely than others to have ear problems that cause scratching. Breeds with floppy ears (e.g., cocker spaniels, basset hounds), narrow or small ear canals (e.g., shar-peis, pugs), or hairy ears (e.g., poodles) may be more likely to develop itchy ears than other dogs.
Most dogs with itchy ears need treatment to feel better. If ear problems are not treated, they can hurt your dog's ears, affect hearing, and make discomfort last longer. Early diagnosis and appropriate treatment are important ways to relieve your dog’s discomfort and protect their long-term ear health.
