Allergy Induced Ear Infections in Dogs
Allergy-induced ear infections are painful conditions that tend to recur in many dogs.
Allergies to fleas, foods, and things in the environment like molds, pollens, and dander are the most common underlying causes for allergic otitis.
Allergies cause the skin barrier to break down and increase the wax production in the ear canal. This allows the low number of normal yeast and bacteria on the skin and in the ear to overproduce and allow more severe strains of bacteria to thrive. This leads to increased inflammation, pain, and discharge from the ear.
Dogs with seasonal allergies tend to get ear infections around the same season each year. Dogs with food allergies or non-seasonal environmental allergies may have ear infections recurring throughout the year.
Since dogs with allergic otitis will have repeated ear infections, this chronic inflammation can cause the ear canal tissue to scar, become calcified, and reduce the opening of the ear canals. This makes treatment even harder as the medication has a hard time reaching the deeper ear canal regions.
Symptoms of Allergy-Induced Ear Infections
The symptoms for allergic otitis are the same as otitis externa but tend to recur during the allergy season or be more frequent year-round.
Shaking the head
Scratching at the ears
Redness to the ear flap or entrance to the ear canal
Discharge from the ear canal
Pain when the ear is touched
Thickening of the ear canal
Rubbing the face/ear on the ground or furniture
Licking the paws excessively (a general sign of an allergy)
Itching or licking other parts of the body (a general sign of an allergy)
In severe cases, if the eardrum ruptures, the infection can spread to the middle and inner ear causing symptoms like head tilt, walking abnormally, circling, falling over, or pain when eating or opening the mouth fully.
TREAT and PREVENT the UNDERLYING ALLERGY
Food Allergy
Up to 15% of dogs can have a food allergy but…
There are no diets that are completely “hypoallergenic”, meaning that they will not cause allergies. The closest we have to this kind of a diet are the hydrolyzed diets that can be purchased through veterinarians. Dogs and cats can be allergic to pretty much any protein or carbohydrate ingredient that can be found in pet food.
The most commonly reported food allergies in dogs and cats are chicken, beef, dairy, and egg (and fish for cats). There is nothing particularly special about these ingredients other than they have been the most common ingredients in pet foods
Rule out Food Allergy with a Food Trial
Simple protein ( ie 1/3 Turkey, 1/3 Carb of Brown Rice, 1/3 Veggie ( ie Kale),plus Sunflower Oil and feed that for 8 weeks
2 cups/20lbs daily
Atopic Dermatitis is the most common cause of allergic symptoms/recurring ear infections in dogs.
In the past it was explained as being primarily due to allergens that were inhaled; now the belief is that these allergens are absorbed in the skin, then cause your dog’s immune system to respond inappropriately
BIOFLAVONOIDS. These are the wonderful group of structures found in the pigment of fruits and vegetables. Quercetin has been effective for people with allergies and may be effective in dogs. Standard dose is 100 mg per 10 lbs of body weight daily.
ANTIHISTAMINES. Benadryl (diphenhydramine) is the most commonly used antihistamine. It is given at a dose of 1 mg per pound of body weight, 2-3 times a day. It is best to consult your veterinarian before using these medications. It often takes 14 days of using these to see if they are helping.
Herbal Antihistamines: NETTLE 1 teaspoon/10lbs daily. QUERCETIN is considered the most effective natural antihistamine with doses of 50-100mg/10lbs daily of the standard supplement.
LICORICE ROOT. Considered ‘natural’ steroid. The dose is ½ ml per 20lbs twice daily of the tincture. Caution if underlying organ dysfunction. Max use for 14 days in a row.
CURCUMIN. 95% curcuminoids can be very helpful to decrease the level of itching and skin inflammation. The dose is 100mg/10lbs of body weight daily
HONEY for ALLERGIES: Local, Unpasteurized
‘natural’ desentization, ½ tspn/10lbs daily for 8-12 weeks,
Homemade Topical Skin Cream that works GREAT!: 2ml of Licorice Root Tincture, 2 tablespoons of Coconut Oil, 1 teaspoon of Honey, 10 drops of Lavender Oil
SOY to STOP the ITCH.
Beta-sitosterol is a sterol (type of fat) found in soy, and it can help decrease the level of pruritis (itchiness) in your dog. In people it is most commonly used for lowering cholesterol levels and improving symptoms of an enlarged prostate (benign prostatic hyperplasia or BPH). Studies have shown that Beta-sitoserol ‘attentuates’ atopic dermatis in animals. The dog Beta-sitoserol dose is 1-2mg/lb twice daily. The one I have used is called Beta-Sitosterol Plant Sterols, 180 Softgels by Now
FATTY ACIDS. These are a must for any allergy. Flax oil, fish oil or Krill Oil for dogs. Krill oil dose of 1000mg/50lbs daily. Fish Oil dose is 1000mg/10lbs daily.
How can I treat and prevent allergic otitis?
TREAT The RECURRING DOG EAR INFECTION
Apple Cider Vinegar is NATURALLY antibacterial and antifungal, so will help with most cases of ear infections. I prefer a 80:20 solution of ACV and Warm Green tea. Apply 5-10 drops twice daily for 7-10 days
Sweet Almond Oil in combination with lavender oil is beneficial when the ears are very inflamed, and the ACV will be irritating and painful. 2 tablespoons of almond oil, 10 drops of lavender oil
ANTI-YEAST MEDS. Medication for yeast in people, will often work in dogs. Canesten and Monistat both work well. You can get the generic forms, look for Clotrimazole (the drug name in Canesten). Apply twice daily for 7-10 days.
NEW Anti-Yeast Ear Recipe.
Green Tea -1 cup
Apple Cider Vinegar -2 tablespoons
Coconut Oil- 1 tablespoon
Ensure this is at room temperature and the coconut oil has melted. You can first use this as a flush to clean the ears, then use as a treatment applying 5 drops in each ear twice a day for 5 days as needed.
Beatrice will be getting a topical ear remedy, as well as the oral Quercetin daily. I'll give you an update as to how she responds, but as I type this newsletter she is curled up beside me snoring, but very smelly :-)
