Adorable Dog wearing an Ambulance Costume Howls his own Siren.

Every time an ambulance drives by Wally howls with them. So this year for Halloween Wally is an ambulance!! It's a Styrofoam box over his body that's designed to look like an ambulance, and it's accessorized with a blinking red collar that makes a siren sound. And when the siren howls, so does the pup.
