Dr. Lauren Baker has a doctorate of veterinary medicine as well as a Masters and a PhD in comparative biomedical sciences from the University of Wisconsin-Madison where she is researching complex genetic traits in dogs.  We start with some basics of genetics and genomics and why dogs are good models for genetic study in order to lay the groundwork to talk about her research into some of the possible genetic influences for cruciate ligament rupture in dogs.  We also discuss the science and value of commercially available genetic testing for dogs both for owners and practicing veterinarians.
