This book covers all aspects of toxicology, including toxic diseases of large animals, small animals, and exotic pets. It provides key information on how poisons affect the body, how the body responds to a foreign substance, how poisonings are diagnosed, and how poisonings are treated. Coverage includes every organ system of every species of animal with details on each body system's susceptibility to poison. Poisons affect animals differently depending on species, breed, age, gender, health status, and reproductive status. This resource addresses these differences, allowing the veterinarian to determine the class of toxicant, the mechanism of action, and the proper course of treatment. If confronted with an unknown poison, the information in this book will assist the veterinarian in formulating a list of potential poisons based on the clinical signs that the animal is exhibiting, and in choosing the appropriate tests to narrow the list to one or a few possible poisons.
