One dog in particular caught Tranter's attention. A female beagle cowered in the corner of her filthy enclosure and stared at Tranter with wide, suspicious eyes. Tranter stooped down to film the female dog, then turned to leave the area. That's when Tranter heard a puppy cry.
"I immediately spun around and thought, where could puppies be?" she told The Dodo. "There was nothing in the pen except for a big wooden box. I knelt down and looked underneath that box, thinking it was the only place where dogs could be. But there was nothing."
Tranter turned her video camera light off and sat on the ground to listen. When she heard the cry again, she started crawling around the pen until she noticed a piece of plaster loose on the wall. Tranter turned her camera light back on and shined it through the gap. There, inside the wall cavity, she discovered four wriggling beagle puppies squashed into the tiny space.
