Being able to count on images of pathologies when carrying out a diagnosis is highly appreciated by veterinarians, and especially in dermatology. Remembering an image of a pathological picture can be very important for the differential diagnosis, and it allows the veterina-rian to be acknowledged for his “Clinical eye”. However this can be a pitfall in the cases in which the picture does not follow the classic pattern of the pathology. This book aims to orientate the clinician towards a correct diagnosis with an ample selection of images. With the inestimable help of eminently clinician collaborators, the author goes further by contributing with non-classical images to orientate the vet in those non-common cases. In each chapter the images are accompanied by the general clinical picture of each disease, where etiopathogenesis of the lesions and the clinical picture are described, as well as the diag-nostic method and the treatment.
