This presentation will review non-allergic dermatologic disorders in our canine patients that can mimic allergic manifestations but are to the contrary based on our dermatologic investigations. While allergies may make up a large portion of our day to day cases, there are other dermatoses that are important to rule out through a thorough investigation, to include the dermatologic database. During this presentation, we will explore a number of case studies, to include both clinical lesion and cytological images, depicting other dermatologic conditions ranging from infectious diseases to auto-immune dermatoses.
