Dogs have lived alongside humans for thousands of years, evolving from their wild ancestors, wolves, into a diverse species that has infiltrated nearly every aspect of human life. While humans have long valued dogs for their loyalty and companionship, scientific inquiry into the minds of dogs is relatively new. The documentary Inside the Mind of a Dog explores dogs' cognitive and emotional world, detailing discoveries that shed light on how dogs think, behave, and form bonds with humans. Scientists hope to understand dogs better by studying canine cognition and improving how we interact with them.
