Itchy skin and digestive issues are common problems with our pups. And sometimes, allergies or intolerances to environmental or food allergens are to blame. If you suspect your dog’s symptoms are due to allergies, you’re certainly not alone. That’s why the commercial market is flooded with supplements that claim to relieve dog allergies and symptoms such as scratching and overall discomfort.
As with all consumer products, some allergy supplements for dogs are higher quality and more effective than others. I’ve done my research to weed through your options, and I think the best allergy supplement for dogs is Pet Honesty Allergy Support Chews. But depending on your dog’s needs, there are many others to consider that might fit the bill better. Let’s dive in to help you find allergy relief for your furry friend among my top picks.

3 Expert Tips
Before you dive into the world of dog supplements to soothe Fido’s discomfort or scratching, it’s important to remember the following:
- Always Ask Your Vet First. Before you give your pup supplements, it’s essential to check with your vet. Giving your pup the wrong supplement can sometimes do more harm than good.
- Give Them Time To Work. Remember that dog allergy supplements can take up to six to eight weeks of daily use to see noticeable benefits. So, don’t give up on them before this.
- Not All Allergy Supplements Work For Every Dog. Whether they work can depend on what’s causing your dog’s allergies and how your pup tolerates ingredients. You might have to try a few before you find the one that works best for your pup.

7 Active Ingredients To Look For In Dog Allergy Supplements
While many herbs and ingredients can help relieve itching and inflammation, these are the major ones you want to remember for an effective allergy supplement for your pup.
- Omega-3 Fatty Acids. These are commonly found in fish oils and have been shown in research studies to help decrease inflammation in allergic dogs. Omega-3s also promote a shiny, healthy coat and joint and heart health.
- Probiotics. Probiotics support stronger gut health, which has been shown to promote a healthy immune response to allergens.
- Quercetin. This natural plant flavonoid acts as an antihistamine, anti-inflammatory, and antioxidant. It’s often paired with bromelain for maximum efficacy and offers cardiovascular benefits. It’s also called “nature’s Benadryl.”
- Colostrum. This contains natural antibodies that can help boost immune health and improve inflammation.
- Turmeric. Turmeric is an antioxidant and anti-inflammatory that can help relieve redness, swelling, and itching.
- Astragalus. This is extracted from the stems or dried roots of the Astragalus membranaceus plant. It has been shown to improve the cellular immune level in immunosuppressive dogs.
- Biotin. This B-complex vitamin supports skin and coat health and is often used to treat hair loss in humans.
How Can I Figure Out What’s Causing My Dog’s Allergies?
Determining the cause of your dog’s allergies can be extremely difficult. We recommend that you consult your veterinarian to diagnose the problem. But another first course of action is to give your pup an at-home dog allergy test kit. These kits test for intolerances to many food and environmental factors. Then, you can share these results with your vet to work on further diagnostics and a treatment plan.
Did You Know?
Pet insurance can cover testing, treatment, and prescription shots or medications for allergies as long as no signs or symptoms appear until after your policy enrollment and waiting periods have passed. Learn more about pet insurance coverage for dog allergies.
How Are Dog Allergies Treated?
Dog allergies and intolerances can wreak havoc on your pup’s well-being. If you struggle to help your pup with constantly itchy skin, we recommend you consult your vet. Itchy skin can be a symptom of other illnesses and health problems. You may also want to learn more about allergy treatment options for different types of allergies and the best allergy medications for dogs.
Changing To A Healthy Diet Can Make A Difference
Feeding your dog a high-quality diet can boost their immune system, which helps protect them from severe skin reactions. If you and your vet think a dog food change might help your pup’s allergy symptoms, you may want to consider our picks for the best dog food for allergies or a fresh dog food delivery service. We have also reviewed Bramble, a plant-based diet option for pups with intolerances to meats.
