Who Stole The Big Pink Dog?

There used to be two big Red Dogs and two big Pink dogs in the center of Santa Monica Blvd in West Hollywood and now one of the pink ones is missing! Someone over night swiped a 200 pound sculpture of a pink dog wearing sneakers and a water bottle on its back. No one saw it happen. How does one steal a large pink 200 pound dog from the middle of a busy street and not be seen? Why does someone steal a big pink dog?
