Lolly – a chow-chow-cocker spaniel mix – was Tony Hertz’s dog for 15 years. “She had long black hair with a little white on her mouth, ears, eyebrows and feet, and a partially marbled tongue. She was quite cute,” Hertz says.

Hertz and Lolly were living in Pismo Beach, California, when he took this shot. At the time he was working on a photography series and book based around shadows, and he had taken her along on one of his regular sunset walks. Over a career spanning three decades, Hertz has photographed queens, popes and a president, but this was an attempt at something more personal. The photo was taken on a grassy area next to a Walmart. As Hertz sat down on a bench for a breather, he noticed in their shadows that Lolly was looking directly at him. “I positioned my phone so it couldn’t be seen in the shadow, composed the shot and then looked toward Lolly so that our profiles would be turned to each other,” he says. Hertz often wears his brimmed hats when seeking out new elements for his series, “to make them consistent with a little noir look”.

Lolly died in November from chronic kidney failure. “There’s a void in my home now,” Hertz says. “Though she lived a good long life, I still miss her very much. The photo reminds me of the love I felt for my faithful companion. She often shadowed me.”
