Using a variety of graphical resources, this atlas describes the cutaneous clinical patterns most commonly encountered in dogs (accounting for 90 % of cases seen in veterinary clinics), as well as the associated aetiologies. For each pattern, corresponding guidelines are provided to ensure correct diagnosis. This book has been designed as an educational guide for veterinary practitioners to facilitate the diagnosis of skin diseases. The wealth of graphical material complementing the text provides veterinary surgeons with reference images with which to compare the cases they encounter in the clinic.
