Amid the World Cup excitement in Mexico City, an unexpected star has captured fans' attention.

Osito, an eight-year-old rescue dog, has become a viral sensation as he rides through the city on the back of his owner's cargo bicycle dressed in Mexico's national team colours.

Supporters stop to take photos and videos with the friendly poodle mix, who has become a familiar sight around fan zones and match screenings.

His owner, Jorge Rangel, says Osito's growing popularity has turned him into a symbol of joy and companionship during the tournament.
