10 Best Allergy Supplements for Dogs
As a dog owner, you know how important it is to keep your furry friend happy and healthy. Unfortunately, allergies can be a common problem for many dogs. But did you know that there are several supplements that can help alleviate your dog’s allergy symptoms? In this article, we’ll explore some of the best supplements for dogs with allergies.

1. Omega-3 Fatty Acids
Omega-3 fatty acids are an essential nutrient that can help reduce inflammation in your dog’s body. This is especially helpful for dogs with allergies, as inflammation is a major contributor to allergy symptoms. You can find omega-3 fatty acids in supplements like fish oil or flaxseed oil. Just be sure to choose a high-quality supplement that is free from contaminants.
2. Quercetin
Quercetin is a flavonoid that has been shown to have antihistamine and anti-inflammatory properties. It can help reduce the severity of allergy symptoms and is often found in supplements designed specifically for dogs with allergies. Quercetin can also be found in foods like apples, onions, and broccoli, but supplements may be a more effective way to provide your dog with a therapeutic dose.
3. Probiotics
Probiotics are beneficial bacteria that live in your dog’s gut. They play a crucial role in maintaining a healthy immune system, which can help reduce the severity of allergy symptoms. Probiotic supplements are available in many forms, including powders, capsules, and chews. Look for a supplement that contains multiple strains of bacteria and has a high colony-forming unit (CFU) count.
4. Digestive Enzymes
Digestive enzymes can help improve your dog’s digestion and absorption of nutrients. This is important for dogs with allergies because they may have trouble digesting certain foods. When food isn’t properly digested, it can lead to inflammation and other allergy symptoms. Digestive enzyme supplements are available in powder or capsule form and can be added to your dog’s food.
5. Colostrum
Colostrum is the first milk produced by mammals, including dogs. It is rich in antibodies and other immune-boosting compounds that can help reduce allergy symptoms. Colostrum supplements are available in powder or capsule form and can be added to your dog’s food. Just be sure to choose a high-quality supplement that comes from a reputable source.
6. Vitamin C
Vitamin C is an antioxidant that can help reduce inflammation and support a healthy immune system. It can be especially helpful for dogs with environmental allergies, as it can help reduce the severity of allergic reactions. Vitamin C supplements are available in tablet, chewable, and powder forms, but it’s important to give your dog the appropriate dose for their size and weight.
7. Turmeric
Turmeric is a spice that contains a compound called curcumin, which has anti-inflammatory properties. It can help reduce the severity of allergy symptoms and improve overall immune function. Turmeric supplements are available in capsule and powder forms, but it’s important to choose a high-quality supplement that is free from additives and fillers.
8. Milk Thistle
Milk thistle is an herb that has been used for centuries to support liver function. It can help improve the liver’s ability to process toxins and allergens, which can reduce the severity of allergy symptoms. Milk thistle supplements are available in capsule and liquid forms, but it’s important to choose a supplement that is specifically formulated for dogs and has the appropriate dosage.
9. Licorice Root
Licorice root is an herb that has anti-inflammatory and antioxidant properties. It can help reduce inflammation and improve immune function, making it a helpful supplement for dogs with allergies. Licorice root supplements are available in capsule and liquid forms, but it’s important to choose a supplement that is specifically formulated for dogs and has the appropriate dosage.
10. CBD Oil
CBD oil is derived from hemp and contains cannabinoids that can help reduce inflammation and improve immune function. It can be especially helpful for dogs with skin allergies, as it can help reduce itching and irritation. CBD oil supplements are available in a variety of strengths and forms, but it’s important to choose a high-quality supplement that is free from THC and has been third-party tested for purity and potency.
