A documentary on the thought processes, intelligence and personalities of dogs, examining their history and relationship with wolves, their domestication and uses in helping people. In particular, we see how dogs are selected and trained to be service dogs.
An interesting look into what makes man's best friend tick. Some decent insights, including looking back on dog's descent from wolves, domestication and breeding and how these shaped their personalities and uses.
The coverage of the selection and training to be service dogs was very interesting and ultimately quite emotional as we see the dogs get placed with various people with different issues, requiring dogs of varying personalities and abilities.
Not quite as profound as I was expecting though. I was expecting some major breakthroughs to be revealed but, unless you're unaware that dogs can be trained to help out humans, a lot of the stuff is hardly revolutionary.
Still, very interesting and who doesn't like to see footage of cute doggies living their best lives!
