Small Animal Internal Medicine for Veterinary Technicians and Nurses is the first comprehensive resource on internal medicine written for the veterinary technician. Organized by body system, each chapter discusses pertinent diseases, from clinical signs, diagnostic testing and prevalence to treatment options and nursing considerations. This comprehensive resource, which includes a companion web site with quizzes and additional images, is a must-have resource for both veterinary technicians and veterinary technician students.
Linda Merrill, LVT, VTS (Small Animal Internal Medicine, Clinical Practice) is the executive director and founding chair of the Academy of Internal Medicine for Veterinary Technicians and organizing committee member of the Academy of Veterinary Technicians in Clinical Practice. She is also a former president of NAVTA and has nearly 30 years of practice experience in small animal, cardiology, oncology, and internal medicine.
