There are hundreds of possibilities. Like humans, dogs can develop allergies to various substances and an allergen may be inhaled or the dog may absorb it through direct contact with his skin. Sensitivity to certain foods may also trigger an allergic reaction. At Seminole Trail Animal Hospital, we carry many foods with novel proteins which help with hypersensitivity often associated with allergies. Iams Veterinary Diet Skin & Coat Plus KO is one example for canine patients with skin allergies, chronic ear infections, and chronic gastrointestinal disorders. This diet contains kangaroo and a novel carbohydrate source oats. It also contains specific ingredients geared towards aiding in digestive health. This can be used with dogs who exhibit any of the following conditions or symptoms: inflamed/itchy skin, food allergies/intolerance, chronic ear infections, inflammatory bowel disease, colitis, chronic gastroenteritis, vomiting, and other issues. If you are interested in using this diet as supportive care for your pet, please contact us for more information.
