Dogs were generally less stressed when they heard music, and they showed a slight preference for reggae and soft rock according to researchers at the University of Glasgow.

The study, published in the journal Physiology and Behavior, built on previous research by the same team that found shelter dogs hearing classical music bark less and lie down more, signs of relaxation. But by the seventh day of classical, the benefits to the dogs in that study had worn off, Evans said, indicating that “the animals were getting habituated with the music, or possibly getting bored.” That’s what led the researchers to try the varied genres.
