++CLIENTS PLEASE NOTE: THIS VIDEO HAS BEEN LOOPED++ <br /><br />Aero the Australian shepherd may be friendly, but possibly not the brightest tool in the shed.<br /><br />In the video taken by Allison Hefferan, Aero is seen barking excitedly – at a van decal made to look like a golden retriever through a window. The dog doesn't seem to realise he's interacting with a piece of vinyl, and continues barking confidently.
