Natural Treatments for Atopic Dermatitis in Dogs

Atopic dermatitis is a prevalent skin condition in dogs, affecting an estimated 10-15% of the canine population. It is characterized by excessive itchiness, known as pruritus, and is a lifelong condition with no known cure. However, effective management can significantly improve a dog's quality of life.

Understanding Atopic Dermatitis

Causes of Atopic Dermatitis

A genetic predisposition is suspected, as certain breeds and family lines of dogs are more prone to developing this condition. The outer layer of the skin, the epidermis, is often defective in atopic dogs. When allergens come into contact with the skin, the immune system mounts an inflammatory response, leading to the characteristic signs of itchiness.

Typical allergens include various pollens, molds, dust mites, and dander (skin cells), among other environmental substances.

Signs and Symptoms

The most prominent sign of atopic dermatitis is intense itchiness, which can vary in severity and may fluctuate over time. Often, this itchiness has a seasonal component, reflecting the specific allergens involved, though it can progress to a year-round problem for some dogs.

Dogs commonly exhibit signs such as scratching behind their elbows, licking and chewing their paws, rubbing their faces, and scooting. Initially, the skin may appear normal, but over time, persistent scratching and licking can lead to hair loss. Affected skin areas may become red, and the hair in these spots can develop a brown discoloration due to saliva staining. As the condition advances, the skin can become darker and thicker. Secondary infections may manifest as rashes, frequently appearing on the belly, behind the front legs, and around the base of the tail.

Breeds and Age of Onset

Atopic dermatitis typically begins to manifest in dogs between 6 months and 3 years of age. Numerous breeds are susceptible, including Labrador Retrievers, Golden Retrievers, Soft-coated Wheaton Terriers, West Highland White Terriers, Jack Russell Terriers, Bulldogs, Boston Terriers, Boxers, Pit Bulls, Shar Peis, Shih Tzus, and Weimaraners, as well as mixed-breed dogs. The condition is more common in dogs where both parents are affected and occurs with equal frequency in males and females.

Diagnosis of Atopy

There is no single definitive test for atopy. Diagnosis is presumptive and based on several criteria:

• Classic signs of itchiness.
• Findings from a physical examination.
• A positive response to treatments for atopy.
• Exclusion of other conditions with similar symptoms, such as flea infestations, parasitic infections (like sarcoptic mange), and bacterial or fungal skin and ear infections.

Conventional Treatment Approaches

Therapy for atopic dermatitis is individualized and may need to be adapted based on seasonal changes and the progression of the condition. A combination of approaches is often employed to maximize success, and determining the most effective options may involve a trial-and-error process.

Veterinary Examination and Management

Your veterinarian will examine your dog for any signs of secondary infections in the skin and ears and recommend appropriate treatments. Dogs with atopy may also have concurrent allergies to fleas and certain foods. Your vet will likely advise using an effective flea and tick preventive. If itchiness persists despite flea and atopy treatments, a food allergy may be investigated.

Topical Therapies

These treatments help remove allergens, moisturize the skin, and address secondary bacterial and yeast infections. They include shampoos, rinses, mousses, and medicated wipes. Some topical products also contain antihistamines and corticosteroids to reduce inflammation.

Allergen-Specific Immunotherapy (ASIT)

Diagnostic testing can identify specific allergens triggering your dog's reaction. This can involve intradermal skin testing or a blood test to detect IgE antibodies to a panel of allergens. While reducing exposure to some allergens might be possible, many are ubiquitous in the environment and unavoidable.

Based on test results, immunotherapy can be formulated for subcutaneous (under the skin) injection or sublingual (under the tongue) administration.

Oral Medications

Oral medications can help reduce inflammation. Corticosteroids like prednisone and prednisolone are highly effective for acute flare-ups but should be used at the lowest effective dose for the shortest duration possible due to potential side effects. Cyclosporine is another effective option for reducing itchiness with fewer side effects than corticosteroids. Oclacitinib (Apoquel) is a newer medication that provides significant relief from itching and generally has a better side-effect profile than corticosteroids.

Antihistamines such as hydroxyzine, diphenhydramine, and cetirizine can be helpful for mild itchiness but are less effective for severe itching. Essential fatty acid (EFA) supplements can be used as an adjunct to other therapies.

Injectable Medications

Lokivetmab (Cytopoint) is a monoclonal antibody administered via subcutaneous injection, typically every 4-8 weeks, to reduce itching.

Natural and Holistic Approaches to Atopic Dermatitis

Many pet owners seek natural remedies to soothe irritated skin and address underlying allergy symptoms safely. While home treatments can provide relief for mild cases, professional veterinary care is essential for more severe or persistent issues.

Identifying Root Causes

Before treating symptoms, understanding the root cause is crucial. Bacterial or yeast infections often develop secondary to allergies.

Soothing Topical Remedies

• Colloidal Oatmeal Baths: Grinding plain oatmeal into a fine powder and dissolving it in lukewarm bathwater provides a soothing soak for itchy skin. A 10-15 minute soak, with gentle massaging of the mixture into affected areas, can offer relief.
• Chamomile, Calendula, and Green Tea Soaks: These herbal teas possess properties that cool and soothe irritated skin, reducing inflammation. They are particularly beneficial for hot, itchy patches at risk of becoming raw. For localized relief, a cooled strong brew can be applied directly to the affected areas.
• Apple Cider Vinegar: Diluted apple cider vinegar (50% water, 50% vinegar) can be used as a topical rinse or soak. Its antiseptic and antifungal properties can help, but it should not be applied to raw or open wounds as it may sting.
• Pure Aloe Vera: Applying pure aloe vera gel directly to inflamed, itchy skin can provide immediate cooling relief.

Dietary Considerations

A dog's diet plays a significant role in managing skin allergies. Focusing on a diet free from by-products, chemicals, and fillers is recommended. Some dogs may benefit from a bland diet of boiled chicken or turkey mixed with rice (a 2:1 ratio of rice to protein). Avoid roasting or frying the meat, as fat can lead to pancreatitis.

Food Allergens: Common food allergens include beef, dairy, eggs, chicken, lamb, soy, pork, rabbit, and fish, rather than solely grains. An elimination diet under veterinary guidance may be necessary to pinpoint specific food sensitivities.

Probiotics and Prebiotics: Introducing prebiotics and probiotics can help improve gut health, as a significant portion of the immune system resides in the gut. A diet high in protein and fat, with very low carbohydrates (minimal grains and mostly green vegetables), may help reduce yeast populations.

Raw Food Diets: Some advocate for raw food diets to eliminate common food allergens and provide easily digestible nutrients.

Supplements and Oils

• Organic Coconut Oil: Possesses moisturizing, antibacterial, and antifungal properties. It can be applied topically to soothe dry skin, create a protective barrier, and help with conditions like eczema, yeast infections, and insect bites. It can also be given internally in moderation.
• Fish Oil Supplements: Rich in essential fatty acids (EFAs), fish oil can help strengthen the skin barrier and reduce internal inflammatory responses.
• CBD Oil: Derived from hemp, CBD oil is reported to offer soothing relief when applied topically or added to food.
• MCT Oil: When free of lauric acid, MCT oil has antibacterial and anti-inflammatory properties that can benefit skin health when applied topically or ingested.

Other Natural Practices

• Epsom Salt Soaks: Soaking paws in an Epsom salt solution for 5-10 minutes daily can help remove environmental allergens and contaminants, while also soothing the skin.
• Yogurt: Plain, unsweetened yogurt can support gut health and may be beneficial for certain types of rashes, hives, or allergies stemming from digestive issues. Consult your veterinarian before adding it to your dog's diet.

When to Seek Professional Veterinary Care

While natural remedies can offer relief, it is crucial to consult a veterinarian for a proper diagnosis and treatment plan, especially for persistent or severe symptoms. Some conditions require immediate veterinary attention:

• Bloating or a twisted stomach (GDV) is a life-threatening emergency.
• Blood in stool or urine may indicate serious underlying issues.
• Persistent coughs, significant changes in appetite or demeanor, or signs of severe infection (e.g., yellow or green discharge from eyes or nose) require prompt medical evaluation.
• If symptoms persist beyond a week, or if your dog develops self-inflicted wounds due to itching, veterinary consultation is necessary to rule out underlying conditions requiring medical treatment.

Important Note: Never administer human medications to dogs without explicit veterinary approval, as dosages and safety profiles differ significantly. Essential oils can also be toxic to dogs, so extreme caution and veterinary guidance are necessary.

Working closely with a veterinarian is key to successfully managing atopic dermatitis and preventing flare-ups. For challenging cases, a referral to a veterinary dermatologist may be beneficial.
