Adorable Puppy Falls Asleep after Listening to Lullaby

The puppy in this clip is 8 weeks old, his name is Taco, and he's a Boston terrier. Taco's owner wants him to go to sleep, so he sings the puppy a lullaby. Does it work? On YouTube Taco's owner writes, "I sing a lullaby to my 8 week old Boston Terrier puppy named Taco as she falls asleep. She begins tilting her head when I hum the song instead of singing it. She gives in right at the end."
