This plucky little pooch name definitely has a bark worse than his bite, angrily yapping at a much bigger dog. <br /><br />The young chihuahua had just arrived at the house when he noticed the older dog standing in the living room. <br /><br />The puppy, named Rooney, barked angrily at the Aspin, named Man U, at the house in Bangkok, Thailand, last Wednesday (August 21). <br /><br />Owner Siriwan Jaiwung, 23, who is a Manchester United fan, said: ''He might be small but he's definitely brave.''<br /><br />++CLIENTS PLEASE NOTE: THIS VIDEO HAS BEEN LOOPED++
