Uga VII, the name of a lineage of English Bulldogs owned by Frank W. “Sonny” Seiler, died Thursday of heart-related causes, the dog’s owner said.

The 56-pound dog, nicknamed “Loran’s Best,” was known as a laid-back mascot who seemed oblivious to crowd noise during boisterous games and would sit patiently as excited fans snapped photos of him. He often roamed the sidelines in a shirt with a ‘G’ stitched on it, sometimes resting on a bag of ice to cool off in his customized dog house.

According to University of Georgia (UGA), Sonny Seiler, the dog’s owner said there were options available for Uga VII’s replacement but no final determination would be made until sometime next year.
