To mark National Puppy Day, Elizabeth Lo’s acclaimed film Stray gives humans rare insight into the canine gaze, courtesy of homeless mutts in Istanbul

From the moment Zeytin makes her first appearance in Elizabeth Lo’s feature Stray, there is no doubt you are in the presence of a unique spirit. As she surveys an Istanbul side street at dawn, her features are alert, her gaze is uncompromising and her deep, dark eyes sparkle with intelligence. There’s something of Katharine Hepburn in The African Queen about her, or maybe Brad Pitt in one of his less kempt moments. But non-dog comparisons don’t do her justice. This is one indomitable bitch.

Lo first encountered Zeytin and her friend Nazar on a 2017 casting trip to Turkey, and knew immediately that she had found the star she was looking for – which is to say, a dog who could carry a human film. “We were wandering through a busy underground tunnel filled with people when suddenly these two giant stray dogs streaked past us,” she says. “They were running with such a sense of purpose and it was so intriguing. What appointments did these dogs have to keep?”
