The Bulldogs have signed former Junior Kangaroo and Panthers Holden Cup captain Andy Saunders.

The 22-year-old prop was part of the Penrith NYC team that won the Holden Cup in 2013 and represented the Junior Kangaroos the following year, before being named in the NYC Team of the Year in 2014.

He is the Bulldogs' second signing this week, following in the footsteps of Wests Tigers forward Rod Griffin.
