For itchy skin on a dog, the first step is to make sure they are current on their flea and tick preventatives. Fleas and mites prefer clean, healthy haircoats, so grooming is not adequate prevention. Topical prevention like Advantix II and Seresto collars may be best at repelling fleas for allergic dogs. Fish oils are the best source of omega-3 and omega-6 fatty acids, which have been shown to improve skin health and reduce inflammation in certain canine skin diseases. Oatmeal has been shown to possess antioxidant and anti-inflammatory properties in both human and veterinary products. Used topically, it helps improve the skin barrier, moisturizes, and may even have UV-protective and antifungal activity. The most effective oatmeal products for dogs are shampoos. Skin health is closely linked to nutrition, so make sure your pet’s food is well-balanced and meets the standards set by the Association of American Feed Control Officials. For dogs already eating a well-balanced diet that still need extra support, look for a sensitive skin and sensitive stomach diet.
