Lhasa Apso puppy Frank takes his role as protector of Erica Kaufman’s twin baby sons seriously. As Kaufman describes, “he typically sniffs and quickly licks the head of the son not featured”. On this occasion, he decided to bond with baby Noah and grew so attached that when Kaufman tried to take the dog away, he growled and snapped at her and continued to groom the happy baby.
