It’s Selena Gomez’s Pet!
That dog you saw earlier belongs to 'Who Says' songstress Selena Gomez! His name is Baylor, aka "Bay," and Gomez loves him to pieces. Gomez adopted the dog in late 2011 and has been head over heels for him since. She is constantly tweeting photos of her puppy, snuggling with him when she's sick in bed or taking him for walks outside on sunny days. What a loving mom she is to little Baylor!
