This five-part series by Plimsoll Productions covered the latest science relating to the behaviour and ecology of dogs, trying to understand how and why they became man's best friend and conveying the effects this millennia-old relationship has had on our own history.
The below shots were taken in the cerrado of Serra da Canastra (Brazil) while looking for the elusive maned wolf; in Thailand, where we followed the daily lives and challenges of stray dogs and of those who keep an eye on them; in the countryside of northern Portugal, where the deep connection between guardian dogs and sheep helps shepherds maintain their herds safe from the Iberian wolf; and finally in Chicago, where we saw how adaptable wild canids can be with coyotes taking over the city's busy streets.
