The Bulldogs have announced the signings of exciting Penrith winger Junior Tia Kilifi, St George Illawarra prop Micky Paea and Cronulla utility Blake Green for the 2010 NRL season.
The club have also agreed on a new contract with the competition's leading try scorer Bryson Goodwin until the end of 2011.
Goodwin, who has scored 18 tries this season after signing from Cronulla at the start of the year, said he was delighted with his first campaign with the Bulldogs and happy to commit his future to the club.
"When I joined the Bulldogs I set myself a goal to play 12 games in first grade," Goodwin said.
"Then when I was picked for the first game of the year I looked beyond that and wanted to play well enough to be in every game."
Tia Kilifi, 21, has signed a two-year deal after an impressive start to his first-grade career with the winning try on his debut against Parramatta in round 17.
The 23-year-old Paea has also signed a two-year deal.
"Mickey gives us a real point of difference, ticking a number of very important boxes which every club requires," Bulldogs coach Kevin Moore said.
"His early-season form was rewarded with selection in the strong Dragons pack before he was hampered by injury. We look forward to Mickey bringing that impact and strong work ethic into our team as well."
