Research/Clinical Interest

Dr. Todhunter is interested in the broad sweep of orthopedic genetic research with a focus on prevention, as opposed to treatment, of hip dysplasia and other inherited orthopedic traits in dogs. He also works to identify genetic markers (single nucleotide polymorphisms) that point to the associated or causal genes and the genes themselves underlying the development of canine hip dysplasia and secondary hip osteoarthritis.  He also has interest in genetic mapping of rupture of the cranial cruciate ligament and elbow dysplasia.
