Dog Ear Health 101: The Case of A Dog Scratching Ear

The Case of A Dog Scratching EarYou’re watching TV and hear the telltale scratch and jingle of a collar: the dog scratching ear problem. 

A dog can be scratching its ear for many different reasons, but it could be a sign that there is an ear problem that needs attention. Itchy ears could mean an infection, which requires a trip to the vet, or just simply itchy ears that need to be cleaned with an ear cleaner and cotton ball.

Dog Scratching Ear…What Could This Mean?

Ear Mites

Ear mites can cause many dog ear problems.

Ear mites are parasitic infections that your dog can pick up from other dogs and cats.  They start on the body and work their way to the earflap and into the canal.

Treating ear mites often requires a trip to the veterinarian.  Treatment usually includes a thorough ear cleaning and topical medication.

Allergies

Just like us, dogs can get allergies too.

Dogs can get itchy skin due to food allergies, flea sensitivity, or different environmental factors like pollen.  Allergic reactions can develop into skin infections in dogs and lead to excessive scratching, head shaking, and hair loss.

Chronic allergies is called atopic dermatitis.

Dog Ear Infection

Problems like allergies and ear mites can turn into ear infections if not treated. Ear infections have many different causes, so it is important to see a veterinarian to diagnose what caused the ear infection to prevent future ear problems. 

Ear infections are typically diagnosed through an examination of the ear canal and taking samples of the discharge and sending it off to a lab for analysis. Ear infections can be prevented by cleaning and proper drying the ears after exposure to water through baths or swimming (to prevent swimmer’s ear). 

Veterinary Medicine suggests regularly cleaning the ear using veterinary-prescribed ear cleaning solution and a cotton ball (never cotton swabs).

Skin Infection

Skin infections can be caused by bacterial infections, skin disease, yeast, and parasites.  Skin infections can spread to the ears and cause itching.

Because there are so many different possible causes, the vet will need to perform a thorough examination which often included blood tests, urinalysis, and skin cultures according to PetMd.

Common causes of skin infections:

  • Sarcoptic Mange (contagious to other animals)
  • Demodectic Mange (not contagious)
  • Cushingtons Disease
  • Lupus
  • Yeast Infection

Yeast Infection

Allergies can lead to yeast infections, which can make a dog very itchy, especially in the ear canal. 

Yeast infections can cause itching, hair loss, and sometimes oily, foul-smelling skin.  Yeast infections can be treated with topical medication or oral medication in persistent cases.

The vet often prescribes a special anti-fungal shampoo to take home and use frequently over a specific amount of time for a yeast infection.

Overall Ear Problems

The cause of itchy dog ears may not always be obvious.

Ear problems can be caused by too much ear wax or a foreign body stuck in the ear canal, which can be easily treated.   Dogs with hairy ear flaps and floppy ears like Cocker Spaniels are more prone to ear infections and other ear problems.

Check and see if the issue is only in the ear or if there are other symptoms on the body.  Look around the ear for any hair loss, or hot spots, and check inside the ear for any odors or discharges. Try to find out as much as possible by examining your dog.

  1. Yes. For a dog up to 100lbs they can have 25mg of benadryl (or off brand) every 4 hours as needed. Over a 100lbs they can have 1 and a half same every 4 hours. Over 150lbs you can give him/her 2 every 4 hours. I would watch for changes in mood. Benadryl can do the opposite of making them tired. It can sometimes cause them to feel agitated, nervous, high strung and hyperactive. If this happens just give them space it will wear off bs and then next time try a smaller dose to see if it helps the problem and also doesn’t effect their mood. Another alternative is Zyrtec (or off brand) the dosage would be different though. Under 50lbs (ask a vet) over 50lbs 1 a day.

  2. Can my dog have a Benadryl for his itchy ear for now my vet said there’s nothing wrong with him maybe allergies but didn’t give me anything for him????
