Top Book to Read on Dog Behaviour and Cognition According to a Behaviourist

As a behaviour scientist, I have done my fair share of reading about dog behaviour and cognition. Some books I could take or leave, but there is one that I read at the beginning of my foray into dog behaviour that has stuck with me to this day and one I still refer my clients to. Reading it will make you more understanding, empathetic, and overall a better dog guardian.
