They advanced to the NRU Premier Division in 1995, winning it for the first time in 1998 and entered the Super League in 2007.

The Wolfhounds began as a social touring side of rugby players in the Boston area looking to travel the United States during their off-seasons with their respective clubs.

Due to their successes while touring (particularly in New Orleans and Texas) and enormous support from the Boston Irish community, the Wolfhounds became an official team and entered into the New England Rugby Football Union (NERFU) Division II in 1992.

An unintended consequence of the establishment was the eventual disestablishment of Beacon Hill RFC (lost most of its first XV pack), the end of Mystic River Rugby Club's appearances as a national level club (lost three key first XV), and the relegation of Charles River RFC (lost complete first XV backline) to Division II.

In 1995, the Wolfhounds met enough success to warrant the leap to the Northeast Rugby Football Union (NRU) Premier Division.

BIWRFC has established relationships with local high school and college sides, which become feeder teams for the Wolfhounds.

In recent years, the Wolfhounds have sent some of these young collegiate athletes abroad to gain experience by playing professionally.

They have also initiated several coaching clinics and courses to build rugby in the Boston area among all clubs.
