CCTV footage has captured the moment a tiny chihuahua's barks were enough to scare off - would-be car thieves.<br /><br />Three lads who pulled up to a residential street were seen trying to open a parked car's doors at two in the morning.<br /><br />But the small dog managed to send them fleeing - with yapping.<br /><br />In the video, two-year-old rescue dog Milo is heard barking and the three men are seen running back to their vehicle and driving away. <br /><br />According to Milo's owner Anna Moomin, 32, this isn't the first time her car was broken into. <br /><br />She said: "This is the fourth time I’ve had men trying to break into my car. "[Milo] did a much better job than the police."<br /><br />Anna, a content creator, thought the group were drunk on their way home from a night out - but the following day she realised items had been stolen.<br /><br />Anna said: "I went to my car in the morning and the contents of my car had been turfed out and spare house keys stolen. <br /><br />"I know I shouldn’t have put them in there but due to my disabilities, I can forget/misplace things.<br /><br />"The time before that was last month when a man in a grey hoodie smashed my passenger window to get 2 cigarettes.<br /><br />"The time before that was probably three months ago when two men were trying to siphon petrol out of my car. <br /><br />"All times were recorded on CCTV and all times the police did nothing."<br /><br />Anna, who is from Barnsley, South Yorks., described Milo as "the best dog ever."<br /><br />Anna said: "He can be very vocal when he hears noises but he’s so caring and loving and likes cuddling with people and dogs he knows. <br /><br />"He can tell when someone’s upset and when I have meltdowns - I’m autistic - he comes straight up and puts his paw on me."<br /><br />The footage was captured on August 22.
