It's not the size of the dog but rather the size of its bark that matters. Just ask a couple of would-be burglars who were chased away by a tiny Maltese pooch in Australia recently. The hilarious video footage shows the little pooch heroically chasing off two men who tried to break into a home. Lynda Knuth, 78, said she was awoken around 6 a.m. by the sound of a commotion earlier this month at her home. The home surveillance cameras show the wannabe burglars trying to enter her home but her dog Marley thwarting the men by racing out to scare them. The men take off as soon as they hear the brave pup coming to defend his home. Marley then chases them to the end of the driveway, barking until his owner comes out to see what the noise was, footage shows.
