Wagg research of 1,000 British dog owners revealed that sleeping patterns may vary depending on the breed of dog, reports the Independent.
Commenting on the research Dr Robert White-Adams said: “When you look at the statistics for which dog breeds are most likely to be up and around at night, and/or causing mischief, it is largely the breeds we associate with being more intelligent, and closer to their working heritages, like collies and spaniels.
