Dogs have appeared on the silver screen since the dawning days of cinema, when their tails wagged silently but joyfully in front of audiences, making viewers laugh, cry, and clap with delight. Dogs are our closest animal companions, and many hours of footage have been devoted to them – on smartphones, movie cameras and everything in between. Nearly as long as humans have walked upright, dogs have padded alongside, too often paying a steep price for this proximity through abuse and neglect. These animals arouse our empathy, but they are subjected to our exploitative nature all the same, a reminder that humans are just animals, fighting to live, sometimes at any cost. Dogs are fodder for rich, emotional stories, but these tend to be aimed at children rather than adults. However, there is the rare film that examines the relationships between dogs and people with an eye to more universal themes. The results range from heartfelt to horrific but are always provocative.
