BUENOS AIRES, Argentina -- Thirteen Argentina followers are roaming the streets of Buenos Aires proudly sporting their team's jersey -- but they're not on two legs, they're on all fours, letting out the occasional bark. As Argentina rides World Cup fever , a dog walker has added his pack to the local fanbase. Nahuel Meneghini, 33, walks the streets of the capital's city center with the dogs wearing the team's jerseys, leashes and collars in support of Lionel Messi 's squad.
