Mascot: Reveille the Dog
Animal: Rough Collie (aka Long-Haired Collie)
Sport: College football
Team: Texas A&M Aggies
Venue: Kyle Field, College Station, Texas
Bottom line: I was confused at first when I learned Texas A&M uses a live dog mascot, so I went to their website for the definition of "Aggie."
It reads, in part, "An Aggie is a student at Texas A&M. In the early 1900s, Texas A&M students were referred to as 'Farmers.'" That clears things up.
Whatever the reason, Reveille saw the opening and broke free from his handler, who, in his defense, got zero help from the folks on the sideline.
