Ooohh Nooo, it’s Otitis Externa! again…
Nearly every dog gets at least one in their lifetime! Ear infections are one of the top 3 most common pet health insurance claim reasons! They’re crazy! They’re everywhere!
Sometimes they are frustrating! They can be hard to beat! They often recur. They are PAINFUL!
Outer ear infections in dogs are most often caused by :
- Bacteria (various kinds, many of which are antibiotic resistant)
There is almost ALWAYS an Underlying Cause that needs to be treated in order to cure the infection and prevernt recurrence.
ALLERGIES to food products– Be on the alert for:
- no other symptoms of allergy such as itchy skin/ persistent licking
- Maybe Bottom scooting
- Maybe Periodic loose stools, diarrhea or vomiting
ALLERGIES to environmental factors ( pollens, dust mites, molds, etc), especially if:
- Licking, scratching other parts of the body, too
Anything that plugs the ear canal such as
- Wax accumulations
- Thick or matted hair in the ear canal
- Foreign bodies such as a grass awns or insects (ticks love ear canals!)
- Tumor or polyps
Water in the ear– from swimming or bathing
Hormone problems suppressing the natural immune system
- Shaking of the head
- Ear scratching
- Red and inflamed ears
- Offensive ear odor
- Black, Brown, reddish or yellowish discharge (fi you think it’s “dirt”, it’s probably not– see a vet!)
- Constant tilting head may signal middle ear infection
Because a number of problems can cause an ear infection, it is important that your dog or cat see the veterinarian at the first sign of symptoms. The veterinarian will also make sure the eardrum is intact before prescribing medication because some medications have been known to result in hearing loss if administered to a pet with a ruptured eardrum. Your veterinarian will prescribe proper medication and treatment.
Examining the ear–Your veterinarian will use an otoscope to look inside your pet’s ear for debris and to check on the condition of the eardrum. If this is painful, your pet may need to be sedated or anesthetized for the exam. If the ear examination reveals a foreign body, tick or heavy debris buildup, sedation may also be required in order for the veterinarian to remove the irritant.
Cytology— Your veterinarian will take a sample of the material in the ear canal and examine it under a microscope (cytology) to determine if an organism caused the infection, and which organisms are involved. This is a critical step of diagnosis and follow up! Different organisms require different medications and the type of organism involved can change over time, even during treatment!
Cleaning- Your veterinarian may need to clean your pet’s ear of debris prior to treatment in order for treatment to be most effective. Some medications are inactivated in the presence of pus. Medication can not treat an infection if there is so much debris in the canal that the medication cannot reach the skin. Cleaning can sometimes be done in the exam room. But anesthesia is often needed if your pet’s ear is too painful or there is an excessive amount of debris. Ears are suuuper sensitive– there is only 1 nerve between the ear and the brain! Making the investment in cleaning, even if it means anesthesia, early in the treatment process will help cure the infection faster and reduce the number of rechecks needed.
Medication treatment–Medication treatment is typically prescribed for one to two weeks. This can be painful for your pet, so be gentle. Your veterianrian may be able to instill long-acting medication in your pet’s ears initially to minimize uncomfortable treatments at home. Depending on your pet’s condition, you may have to do daily cleaning at home. Your veterinary team will show you how.
Prompt diagnosis and proper treatment will speed your pet’s recovery. .Be prepared for recheck examinations with your veterinarian. Only your vet, using an otoscope, can ensure that the infection is cleared up all the way to the ear drum. Ear infections can be frustrating and take some time to treat due to the number of factors that complicate recovery:
- The cause of infection can change during the course of treatment-– from a bacterial to a yeast infection, for instance
- Resistance to typically used medications.
- Not cleaning the ear enough so that medication can reach the infection
- Not treating the ears deeply enough
- Not treating long enough to clear the whole infection
- Underlying problems such as allergies or thyroid disease.
The longer an ear infection goes untreated, the harder it is to get rid of. Your pet will be in pain until you start treatment. Heavy head shaking, a sign of infection, can result in broken blood vessels in the ear flap (this is commonly called an aural hematoma) that requires surgery. Frequent ear infections can damage the eardrum and close the ear canal, in which case surgical reconstruction may be necessary.
Recurrence of infection may happen for a number of reasons. Sometimes the infection is persisting rather than recurring because it was not cured the first time. This happens most often when patients are not rechecked with the veterinarian. An infection may look cleared at the ear opening, but still be brewing deep in the canal, near the ear drum.
Recurrences should always be treated and the underlying cause treated. Dogs should not “always” have ear problems. They are painful and often a sign of a bigger problem!
- Prevent water from getting in your dog’s ear during baths– put a cotton ball in ear opening to catch any accidental water that may get in.
- If your dog is a frequent swimmer, ask your veterinarian for a drying ear wash to use nightly during swimming season.
- Use any ear flush prescribed for your veterinarian on a regular schedule.
- Treat the underlying causes!
|Q.||What is the best way to keep my dog’s ears dry?|

|Q.||How soon should I take my pet to the veterinarian’s office if I think it has an ear infection?|
|A.||Call and make an appointment immediately. Your pet is in pain. Your vet needs to determine the source of the problem and prescribe a course of treatment as soon as possible.|
