Cuteness overload is coming to Georgetown University in the form of a 4-month-old bulldog puppy.

Jack Jr., a.k.a. J.J., will serve as mascot-in-training to official bulldog Jack, a beloved figure on campus and at Hoya sporting events. University officials made the announcement Friday, complete with pictures and an adorable video of the puppy . . . well, looking adorable.

The puppy — described as “laid back”— is a gift from bulldog breeders Janice and Marcus Hochstetler, who have two children attending Georgetown. He’ll live on campus with Jack and the Rev. Christopher Steck, an associate professor of theology, and be tended by the team of 20 students who walk the dogs daily. Steck is headed to San Diego to pick up J.J., who’ll be introduced to the student body at an official welcoming ceremony April 13.

The new addition to the Hoya family is not a replacement for 8-year-old Jack, who injured his left leg this month; plans have been underway since J.J. was born in December. “Really excited about the new puppy, and, just to be clear, Jack is NOT being retired,” Steck tweeted Friday.

As the university puts it: “After consulting with experts earlier this year and learning of the opportunity to take in a new puppy, Steck decided the dogs would benefit from a mentor-mentee relationship.” J.J. (no relation to the current Jack — by tradition, all the dogs carry the name) will be the sixth bulldog to serve as the school’s four-legged mascot.

Jack is scheduled for surgery in April and is expected to make a full recovery. He will return to his official duties in the fall “to appear at games and teach J.J. what it means to be a Hoya.”
