Jackson, 28, has played 181 games for the Bulldogs since making his NRL debut for Canterbury in 2012.
The former Australia and New South Wales representative extended his stay with the Bulldogs on Sunday.
"It really is fantastic news and a great early Christmas present for our members and fans that Josh has re-signed with the club," Bulldogs chief executive Andrew Hill said in a statement.
"He is an incredibly popular figure here at Belmore and he represents everything that is great about our club in the way that he carries himself on and off the field.
