A pheromone that attracts female pigs to males also silences barking dogs, researchers report in The Professional Animal Scientist. An animal welfare researcher at Texas Tech University discovered by chance that spritzing androstenone, a steroid and pheromone secreted by male pigs, instantly stopped his pet dog from making noises. Further research confirmed that one spritz of the foul-smelling “pig perfume” does the trick, with no effect on the dogs’ cardio functioning. The researchers have developed the “perfume” as a commercial product for pet owners, though they caution that it should be used only as a training tool.
