If you’ve noticed your dog constantly scratching, chewing on their paws, or suffering from red, irritated skin, you’re not alone. Allergies are one of the most common health concerns for dogs today. From environmental triggers like pollen and dust mites to food sensitivities, allergies can make life miserable for your furry companion.
While conventional treatments like steroids and antihistamines may bring temporary relief, many pet parents worry about side effects and long-term health risks. That’s why natural supplements for dog allergies are becoming increasingly popular. These holistic solutions help reduce symptoms, strengthen your dog’s immune system, and promote overall well-being—without the harsh effects of pharmaceuticals.
In this in-depth guide, we’ll cover the top five natural supplements for dog allergies, including Omega-3 fatty acids, probiotics, quercetin, colostrum, and herbal remedies. We’ll also recommend trusted Amazon products you can easily purchase to start helping your pup today.
Why Natural Supplements for Dog Allergies?
Before diving into the best supplements, let’s understand why they’re effective.
- Target Root Causes: Instead of masking symptoms, natural remedies often address the underlying inflammation or immune imbalance causing allergies.
- Fewer Side Effects: Unlike steroids or synthetic antihistamines, supplements like fish oil or probiotics are generally safe for long-term use.
- Boost Overall Health: Many allergy-friendly supplements improve more than just skin health—they also support digestion, joint health, and immune balance.
- Holistic Care Philosophy: Supplements fit into a broader lifestyle of natural pet wellness, including clean diets, reduced exposure to toxins, and stress management.
1. Omega-3 Fatty Acids for Skin & Coat Health
Omega-3 fatty acids—especially EPA and DHA—are among the most recommended natural supplements for dogs with allergies. Found in fish oil, krill oil, and algae oil, these essential fatty acids help reduce inflammation, moisturize dry skin, and restore shine to dull coats.
Dogs with skin allergies often have inflamed, itchy patches that worsen when left untreated. Omega-3s work by calming the body’s inflammatory response, making them ideal for dogs with environmental allergies, food sensitivities, or flea allergy dermatitis.
Benefits of Omega-3s for Dogs with Allergies
- Reduces itching and scratching
- Supports skin barrier function
- Helps manage chronic hot spots
- Improves joint mobility (bonus for senior dogs)
✅ Recommended Amazon Products:
- Wild Alaskan Salmon Oil for Dogs – Liquid form, easy to pump over food.
- Fish Oil Softgels for Skin & Allergy Relief – Convenient capsule option for picky eaters.
💡 Tip: Always choose a product specifically formulated for pets. Human fish oil capsules may contain additives unsafe for dogs.
2. Probiotics for Dogs with Allergies
The gut and skin are deeply connected—a relationship often called the gut-skin axis. Dogs with allergies frequently suffer from an imbalanced gut microbiome, leading to weakened immunity and heightened sensitivity to allergens.
Probiotics restore healthy gut bacteria, improving digestion and reducing systemic inflammation. When paired with prebiotics (fiber that feeds probiotics), they create a thriving gut environment that helps the body respond more calmly to allergens.
Benefits of Probiotics for Allergic Dogs
- Strengthens immune system
- Reduces yeast infections and “yeasty dog smell”
- Decreases gastrointestinal upset linked to food allergies
- Promotes better nutrient absorption
✅ Recommended Amazon Products:
- Dog Probiotic Chews with Prebiotics – Tasty chews that double as treats.
- Multi-Strain Probiotic Powder for Dogs – Easily mixed into wet or dry food.
💡 Tip: Look for probiotics with at least 3–5 different strains for maximum benefit.
3. Quercetin: The Natural Antihistamine
Quercetin is a powerful plant flavonoid often referred to as “Nature’s Benadryl.” It works by blocking histamine release, which is the body’s natural reaction to allergens. This makes it incredibly effective for dogs suffering from seasonal allergies like pollen, dust, or mold.
When combined with bromelain (an enzyme from pineapple), quercetin’s absorption increases, enhancing its effectiveness.
Benefits of Quercetin for Dogs
- Acts as a natural antihistamine
- Reduces inflammation and swelling
- Helps control watery eyes, sneezing, and runny noses
- Safe for long-term use during allergy season
✅ Recommended Amazon Products:
- Quercetin + Bromelain Dog Supplement – Specially formulated for pets.
- Allergy Relief Chews with Quercetin & Vitamin C – Combines antioxidants for added immune support.
💡 Tip: Not all human quercetin products are safe for dogs. Always use supplements formulated for pets.
4. Colostrum Supplements for Immune Balance
Colostrum is the nutrient-rich “first milk” produced by mammals after giving birth. Packed with antibodies, growth factors, and immune-boosting compounds, it can help strengthen your dog’s defenses against allergens.
By improving immune function, colostrum reduces overreactions to harmless triggers like pollen or certain foods. Over time, this leads to fewer flare-ups and better allergy control.
Benefits of Colostrum for Dogs with Allergies
- Boosts immune system resilience
- Reduces chronic allergy symptoms
- Promotes faster healing of skin lesions
- Supports gut health and overall vitality
✅ Recommended Amazon Products:
- Bovine Colostrum Powder for Dogs – Easily sprinkled over meals.
- Immune-Boosting Colostrum Chews – Tasty, convenient option.
💡 Tip: Colostrum is especially helpful for dogs with autoimmune-related allergies or frequent infections.
5. Herbal Blends for Allergy Relief
Nature provides a wide range of herbs with antihistamine and anti-inflammatory properties. Many holistic supplements combine these herbs into chews, powders, or capsules for allergy support.
Common Herbs for Dog Allergies
- Chamomile: Soothes irritated skin and calms digestion.
- Nettle Leaf: Natural antihistamine that helps with seasonal allergies.
- Turmeric: Anti-inflammatory powerhouse for itchy skin and joints.
- Licorice Root: Reduces inflammation and supports adrenal health.
Benefits of Herbal Allergy Supplements

Lifestyle & Diet Tips to Support Allergy Relief
Supplements work best when paired with other healthy lifestyle choices. Here are a few additional steps you can take to help your dog:
- Switch to a Limited-Ingredient Diet: Food sensitivities often trigger skin issues. Try a novel protein diet (e.g., duck or venison).
- Regular Bathing: Use hypoallergenic shampoos with oatmeal or aloe vera.
- Keep Bedding Clean: Wash dog beds frequently to reduce exposure to dust mites.
- Vacuum & Air Purify: Reducing indoor allergens makes a huge difference.
- Add Coconut Oil: A natural anti-inflammatory and moisturizer for itchy skin.
