Yale's Handsome Dan XVII (9.5 years old) died on Aug 12, 2016 from a brain tumor. They identified their new mascot a month later and debut Handsome Dan XXIII in Nov 2016.
It took them two months!
Yeah, we are dragging our feet on this. Yale and Miss State replaced their mascot recently in a very quick manner. It's been over 11 months and we have no mascot!
Yale did go with a different breed, the Olde English Bulldogge.
