Which of the following is not typically included in the differential diagnosis for chronic pruritus in a dog?

Chronic pruritus in dogs is usually driven by allergic or inflammatory skin diseases and parasites that cause itch directly in the skin. Classic culprits include atopic dermatitis, flea allergy dermatitis, and food-induced dermatitis because they provoke ongoing itch through immune or irritant pathways and often present with persistent scratching or rubbing and possible secondary infections. Diabetes mellitus, by contrast, is a systemic metabolic disease; itch is not a defining feature of diabetes itself. Therefore, diabetes mellitus is not typically included in the differential diagnosis for chronic pruritus. If a diabetic dog is itchy, you would still evaluate for the usual itchy skin diseases and any secondary infections rather than attributing the pruritus to diabetes.
