What do dogs know and understand of the world? Do their emotions feel like our own? Do they love like we do? What do they think of us? Author and zoologist Jules Howard takes a look at the many scientists before him who turned their analytic eye on their four-legged companions. Leagues of psychologists and animal behaviourists have built upon the study of dogs and have fetched increasingly important results. Wonderdog reveals the study of dogs to be key in the advancement of compassion in scientific research, and crucial to making life on Earth better for all species.
