Dr Kidd received a Bachelor of Science in Bacteriology from the University of Wisconsin-Madison in 1987, and graduated from the University of Wisconsin-Madison's School of Veterinary Medicine (UW-SVM) in 1991. After several years in private small animal practice, she returned to the UW-SVM to obtain specialty training in Small Animal Internal Medicine. She completed the program in July of 2000, and achieved board certification by the American College of Veterinary Internal Medicine at that time. She stayed on as a Clinical Instructor of Small Animal Internal Medicine until December of 2002. Dr Kidd then left Madison to pursue research training at the Intracellular Pathogens Research Laboratory at North Carolina State University's College of Veterinary Medicine, under the mentorship of Dr Ed Breitschwerdt. There she obtained a PhD in Immunology with a minor in Molecular Biology. Her PhD research centered on the molecular characterization of Spotted Fever Rickettsiosis in dogs. She then completed a postdoctoral fellowship at The Scripps Research Institute investigating the anti-inflammatory properties of insulin in gram negative sepsis and mechanisms of thrombosis in pro-inflammatory states in the laboratory of Dr Nigel Mackman.

Professional Experience

Dr Linda Kidd is an Associate Professor of Small Animal Internal Medicine. She joined the faculty in April of 2007. Dr Kidd is the director of the CORE Small Animal Internal Medicine course for fourth year veterinary students. She also serves as a content-expert in Small Animal Internal Medicine, and is pursuing collaborative clinical research projects with internal medicine specialty practices in Southern California, North Carolina State University, Colorado State University, and The University of North Carolina Chapel Hill.


The most important role of an instructor of Small Animal Internal Medicine is to provide veterinary students with the tools necessary to effectively apply knowledge in the clinical context so that their approach to problem solving results in optimal patient care. Similarly, the role of mentor in the clinical research setting is to provide the student with the tools necessary to ask research questions that result in clear and meaningful conclusions. At the heart of every teacher-student interaction is the fostering of a passion for life-long learning and the desire to benefit animals and their human companions.

Research Interest

Her clinical and research interests include Rickettsioses and Anaplasmosis, immune-mediated diseases, endocrinology, sepsis, and disorders of hemostasis and thrombosis. She is also interested in research regarding the efficacy of using patient SOAPS and videoconferencing rounds for learning internal medicine in a distributive model of veterinary clinical education.
