What key feature characterizes a Limited-Ingredient Diet (LID) formulated for sensitive Westies?

Featuring a single novel protein source and fewer carbohydrates

Because West Highland White Terriers frequently display adverse food reactions manifesting as dermatological issues, Limited-Ingredient Diets (LIDs) are often utilized. The core principle of an LID is simplification: it deliberately restricts the number of different ingredients to make identifying and eliminating potential triggers easier. This usually involves presenting only one novel protein source—a protein the dog has not encountered frequently—alongside a reduced amount of carbohydrates. These diets frequently aim to exclude common dietary culprits known to cause sensitivity issues, such as wheat, corn, and soy, thereby reducing the overall burden on the digestive and immune systems.
