Gumbo (mascot)

Gumbo the Dog is one of two official mascots of the NFL's New Orleans Saints, the other being Sir Saint. Gumbo is in the form of a Saint Bernard dog and wears the number 00. It was the Louisiana Restaurant Association's gift to the Saints. From the New Orleans Saints' website:

Even though Gumbo went into a brief retirement, he was brought back by popular demand.

For years, Gumbo was, in fact, a real Saint Bernard dog that roamed the sidelines in Saints' apparel for dogs. The reason for choosing this breed of dog is the fact that Orleans Parish (where the City of New Orleans lies) shares a border with St. Bernard Parish to the east. The present mascot consists of a person wearing a Saint Bernard dog head and a football uniform. He is usually seen on the sidelines during games near the goalpost and sometimes celebrates touchdowns with Saints players.
