Ear Mites in Dogs and Cats: Signs, Causes and How to Treat Them

Ear mites are one of the most common causes of ear trouble in cats, especially kittens, and they show up in dogs too, particularly puppies and dogs that mix with other animals. According to the MSD Veterinary Manual, they are highly contagious and pass easily between cats, dogs, rabbits, and ferrets through direct contact. This is why a whole litter of street kittens will often have them, and why one infested pet can pass mites to every animal in the house.

Worried your pet has ear mites? You can check the symptoms free in the Omelo app in about 30 seconds and see whether they point to a vet visit. In India, you can also book a video consultation with a licensed vet for ₹349 at vet.beomelo.com if you want a professional to look at what you are seeing.

• Intense scratching at the ears, sometimes hard enough to break the skin.
• Frequent, vigorous head shaking, as if trying to fling something out of the ear.
• A dark, dry, crumbly discharge inside the ear that looks like coffee grounds or ground black pepper. This is a mix of wax, blood, and mite debris and is one of the most recognisable signs.
• Redness and inflammation of the ear canal and the flap.
• A faint odour from the ear, though a strong or foul smell points more towards a secondary infection.
• Scabs, hair loss, or raw patches around the ears, the back of the neck, and the base of the tail, from a pet scratching and grooming.
• Restlessness and irritability, because the itch is constant.

In cats especially, the coffee-ground discharge and non-stop ear scratching are a strong clue. In dogs the picture can be less obvious, and ear mites can be mistaken for an ordinary ear infection. That overlap is exactly why a vet check matters.

You cannot reliably tell them apart by looking, and treating the wrong thing wastes time and money. A vet takes a swab of the ear discharge and looks at it under a microscope. Mites and their eggs are usually easy to spot this way. If there are no mites, the same swab often reveals yeast or bacteria instead, which need completely different treatment. This is why reaching for a leftover ear medicine or an over-the-counter drop without a diagnosis so often fails.

There is one more reason not to guess. Before putting anything into an ear, a vet checks that the eardrum is intact, because some ear medicines can cause harm if the eardrum is ruptured. That is not a call to make at home.

• The ear is clearly painful, and your pet cries out or pulls away when it is touched.
• The ear flap is swollen, hot, or has ballooned up. Heavy scratching can burst a blood vessel and cause a soft swelling called an aural haematoma, which usually needs a vet.
• Your pet tilts its head to one side, loses balance, walks in circles, or seems disoriented. This can mean the deeper ear is involved.
• There is pus, a foul smell, or bleeding coming from the ear.
• Sudden signs your pet cannot hear well.

These point to complications or a deeper infection rather than mites alone, and waiting can make them worse.

• Cleaning the ear. The vet, or you at home with guidance, gently removes the crumbly debris so that medicine can reach the ear lining. Never dig into the ear with cotton buds, which pushes debris deeper and can injure the canal.
• A prescribed miticide. Many vets now use a modern spot-on parasite product applied to the skin, which clears mites over a few weeks and is simple to give. Older ear-drop treatments also work but must be continued long enough to cover the full mite life cycle, since eggs left behind can hatch and restart the problem.
• Treating secondary infections. If yeast or bacteria have taken hold from all the scratching, the vet treats those alongside the mites.
• Treating every pet in the home. The MSD Veterinary Manual advises treating all in-contact dogs, cats, and rabbits at the same time, even the ones that look fine, because mites spread by contact and a single untreated animal re-infects the rest.

Most pets are far more comfortable within days of starting the right treatment, and the itching settles as the mites die off and the inflammation calms down. Your vet may recheck the ear to confirm the mites are gone.

Please avoid a few common mistakes. Do not pour oil, coconut oil, or home remedies into the ear in the hope of smothering the mites, as this rarely clears an infestation and can trap debris and worsen an infection. Do not reuse an old ear medicine from a previous pet or problem. And do not insert cotton buds deep into the canal. If you are unsure whether it is really mites, get the swab done first rather than treating blindly.

• Check any new pet's ears. Kittens and puppies, particularly rescues and strays, very often carry ear mites. Have a vet check a new arrival and keep it separate from your other pets until it is cleared.
• Use a parasite preventive that covers ear mites. Several modern flea and tick spot-ons and chewables also protect against ear mites. Ask your vet which product fits your pet's age, weight, and lifestyle rather than picking one off a shelf.
• Keep up routine ear checks. A quick weekly look inside the ears helps you catch dark discharge or redness early, before scratching causes damage.
• Treat the whole household together when mites appear, so you are not passing them back and forth.

Prevention is far easier than treatment, and it spares your pet weeks of itching.

Omelo does not diagnose, treat, or prescribe, and it cannot confirm ear mites. Only a vet with an ear swab under the microscope can tell mites apart from a yeast or bacterial infection. Think of the app as the step that helps you decide to go and how fast, not a replacement for the clinic.

In India, if you would like a licensed vet to weigh in before you travel, you can book a 15-minute video consultation for ₹349 at vet.beomelo.com. A vet can look at the ear and symptoms you are describing and help you plan the next step, including an in-person ear swab when it is needed. For a pet in obvious pain or distress, go to your nearest vet or emergency clinic straight away.
