I took this course as out of pure casual interest, as I am already in the (human) medical field. Nevertheless, I deeply enjoyed this course and feel that my understanding of common domesticated animals (especially dogs and cats) has increased. This course is recommended for casual learners and those who are thinking of going to the veterinary field. The parallels in clinical approaches between human and veterinary medicine are truly interesting, and the historical perspective is endearing. I realized that with the emerging importance of One Health, (human) physicians should begin to take heed, perhaps, of the unique strengths and coverage of veterinary medicine for medicine and public health purposes.
