Dog lovers will think they already know everything there is to know about their favorite furry companions, while those indifferent to the animal might think a film will do little to sway their opinion. But Netflix’s Inside the Mind of a Dog makes a surprisingly compelling case for diving deeper into canine psychology. Experts weigh in on their intelligence, which many believe surpasses that of apes, our closest mammal relative, as well as their loyalty and charm. People take the latter two for granted, but they’re actually part of a successful evolution strategy experts have dubbed “survival of the friendliest.” The documentary is full of interesting takes like these, but what really tugs at the heartstrings are the stories of the service dogs we follow. It helps, too, that the movie is narrated by an enthusiastic-sounding Rob Lowe, himself an eager dog owner, and peppered with engaging animations and adorable pup clips.

The noble service dogs and their hardworking trainers.
