Very visual handbook aimed at veterinary professionals and dealing with everything related to fleas and ticks, focusing particularly on clinical issues in dogs and cats. The first part is entirely dedicated to fleas (including their identification, life cycle, clinical signs derived from flea infestation, flea allergy dermatitis (FAD), and prevention and control measures, among others). The second part describes thoroughly everything that involves ticks infestation (including species identification and their geographic distribution, feeding behaviour, the biting process, diseases transmitted by ticks, prevention and control measures, etc.).
