What are ear mites?

Ear mites are tiny skin parasites that cause intensely itchy ears, a build-up of earwax, and ear infections. Ear mites can affect dogs of any age but are most common in puppies. They can also affect other animals such as cats and ferrets.

How did my dog catch ear mites?

The most common way for a dog to catch ear mites is from another dog, but they can also survive in the environment for months so it's possible your dog could have caught them from your home, garden or while out and about.

When to contact your vet

Always contact your vet if you think your dog has an ear problem.


Ear mite treatment

  • Your vet will give your dog a treatment to kill their ear mites (likely to be a tablet or ‘spot-on’).
  • Your dog may need more than one treatment to make sure all their ear mites are dead.
  • Ear mites are contagious so you will also need to treat any other dogs and cats in your household.

Ear cleaner

  • It’s likely that your vet will prescribe your dog an ear cleaner for use at home.
  • Once a day ear cleaning will help clear out any excess wax and debris from your dog’s ears.

Medicated eardrops

  • If necessary, your vet will prescribe eardrops to help with inflammation, pain and infection.
  • If your dog is given eardrops, make sure you follow the instructions and complete the course (even if your dog’s ears seem better part way through).

Treat your home

  • Ear mites can survive in the environment for months so you will need to spray your home, and hot wash pet items such as bedding and grooming equipment.
  • Household flea spray is effective against ear mites in the home but never use it directly on an animal. Household flea spray often contains ‘permethrin’, which is highly toxic to many species including cats, fish and birds.

Ongoing care

Your will need to keep an eye out for any returning symptoms and contact your vet if you are concerned. If your dog is prone to dirty ears, you may need to clean them from time to time.

If your dog’s ear mite problem is treated quickly, they are very likely to make a full recovery.

Home remedies for ear mites

There are many products on the market that claim to kill ear mites, but those available without a prescription are usually less effective than a licenced product from your vet. We recommend seeing your vet if you suspect your dog or puppy has ear mites – they will provide you with an effective treatment and check their ears for any other problems. Leaving an ear issue untreated for too long can lead to serious problems.


Regularly treating your dog for fleas is the best way to prevent ear mites. Many of the products we use to kill fleas or other parasites also kill ear mites.

When you welcome a new dog into your life, consider getting dog insurance straight away before any signs of illness start. This will give you peace of mind that you have some financial support if they ever get sick.
