This is Tia, a 5 and a half year old Staffordshire Bull Terrier cross breed. Ever since she was a pup Tia has been rocked to sleep by her mom singing to her and it works so well that now she doses off whenever she recognizes the familiar tune.
One afternoon, mom decided to check how effective her lullaby is and that’s when this happen. As you can see in the beginning of this video, Tia was fully awake, but watch her eyes as soon as her owner started singing. The eyelids closing, the head getting heavier, and the fact there was a pillow nearby didn’t help her stay awake either. Makes me sleepy just watching this.
