I personally think that Reveille kicks Uga's ass.
Not only is she better looking, but she's been around longer than Uga.
Reveille I came to Texas A&M in January 1931. A group of cadets hit a small black and white dog on their way back from Navasota. They picked up the dog and brought her back to school so they could care for her. The next morning, when "Reveille" was blown by a bugler, she started barking. She was named after this morning wakeup call. The following football season she was named the official mascot when she led the band onto the field during their half-time performance. When Reveille I died on January 18, 1944, she was given a formal military funeral on the gridiron of Kyle Field. She was then buried at the north entrance to the field, as all Reveilles are, facing the scoreboard so that she can always watch the Aggies outscore their opponent.

After construction of the Zone at Kyle Field, which obstructs the view of the Reveilles, a small scoreboard was placed on the outside of the Zone, so they could always see how their Ags were doing.
My favorite part of the Rev tradition, is that she attends all classes with the Mascot Corporal of Company E-2. If Rev barks in the middle of class, Class is over for the day!
