Just like people, dogs can suffer from allergies. Some dogs have environmental allergies which may be seasonal. Other dogs may have allergic reactions to certain foods and ingredients in their diet. Allergies, if left untreated, can be very uncomfortable for dogs. Dogs may experience a variety of symptoms if they are struggling with allergies. Common symptoms include watery eyes, sneezing, itchy skin, dull coat, rashes, dandruff, and scaly skin—all of which can lead to dogs excessively licking, scratching, and/or chewing in an attempt to alleviate the itchiness. These skin allergies can lead to the development of hot spots and other sores. Daily supplements can provide anti-itch support to help relieve dermatitis skin conditions resulting from allergies.

What to Consideration When Purchasing Allergy Supplements for Dogs

Allergy Testing:​ If you think your dog is struggling with allergies it's a good idea to mention this at your dog's next vet appointment or schedule an appointment with your dog's veterinarian. Allergies can range from minor to severe and may require prescription oral and topical medication to treat. Your veterinarian may also determine that your dog should see a specialist who will be able to conduct allergy testing to determine what exactly your dog is allergic to.

Dog-Specific Products:​ If you have a dog who has allergies, or you suspect your dog has allergies, it's important to use products that are safe for dogs. Some human medications like Benadryl are generally safe for most dogs, but it's best to use supplements and treatments specifically made for dogs.

Dosage:​ When selecting an allergy supplement to add to your dog's diet, make sure to follow all recommended instructions for how much of the supplement to feed your dog based on their weight and age. In the event of accidental overdose, or if your dog eats more than the recommended dose of an allergy supplement, contact your veterinarian or an emergency veterinary clinic for support.
