The canine practice is constantly evolving in response to the growing needs of animal owner's demands. A large amount of veterinary medicine evolution progresses through human medicine translation. But also, substantial work in human medicine has evolved by translating from research related to veterinary medicine. Being part of one health, these two disciplines (veterinary and human medicine) increasingly tend to go hand in hand. Since dogs are our housemates, they live in our environment, are subject to the same conditions and aggressions, and develop comparable pathologies and diseases. Using this coexistence, diagnosis and treatment protocols could also come closer together. Nevertheless, veterinary medicine is greatly limited by its cost. The diagnosis tools tend to be the same as in humans. They are adapted to the different anatomy and physiology, but with controlled costs most of the time, they are not applied with the same protocols or with the same frequency. Still, every day, we become aware of new diagnostic and treatment methodologies that are being applied to dogs. These methodologies and treatments arise from the need for adaptation and, sometimes, with great innovation, also allowing the evolution of these same tools for application in human medicine. This book aims to showcase innovation in protocols, treatments, products, and ideas in canine practice.
