For those who've said lullabies don't really work, this video will surely prove them wrong --- well, when it comes to dogs, anyway.
In a recently uploaded Youtube video, a young boy hums a lullaby to put an adorable puppy to sleep. The lullaby works a lot faster than one may expect: The dog drifts to sleep in a matter of seconds.
However, the cute pup is not the only canine to fall asleep while listening to German composer Johannes Brahms' "Lullaby." Charlie the dog was also lulled to sleep when the same song was played in another video.
