This is what we found on Wikipedia regarding the Canterbury Bankstown Bulldogs:

The Canterbury-Bankstown Bulldogs are an Australian professional rugby league club based in Belmore, a suburb in the Canterbury-Bankstown region of Sydney. They compete in the NRL Telstra Premiership, as well as competitions facilitated by the New South Wales Rugby League, including the NSW Cup, the Jersey Flegg Cup, NSWRL Women's Premiership, Tarsha Gale Cup, S. G. Ball Cup and the Harold Matthews Cup.

The club was admitted to the New South Wales Rugby Football League premiership, predecessor of the current NRL competition, in 1935. They won their first premiership in their fourth year of competition with another soon after, and after spending the 1950s and most of the 1960s on the lower rungs went through a very strong period in the 1980s, winning four premierships in that decade. The club won the first National premiership in 1995, but would defect to Super League in 1997 during the Super League war. They would return in 1998 for the first NRL season, where they have played since.

Known in 1995 as the Sydney Bulldogs, they reverted to the Canterbury-Bankstown Bulldogs until 1999 before changing their name to the geographically indistinct The Bulldogs before reverting again in 2009 to their current name. The club has won 8 premierships, with their most recent premiership in 2004. In 2012, they won their most recent minor premiership. They last played in a Grand Final in 2014 losing to South Sydney. They are commonly referred to as Canterbury, the Bulldogs or just the Dogs.
