The Bulldogs have locked away an important piece of their future, re-signing Marcus Bontempelli until the end of 2019.

The talented 19-year-old showed his faith in the direction the club is heading by agreeing to the long term deal.

"My teammates, coaches and staff are just an extended part of my family and I feel very privileged to come in to work every day to help improve our club with them," Bontempelli said on Sunday night.

"I just couldn't be prouder to be a Western Bulldogs player and I know that will continue well into my career."

He has kicked 32 goals in 37 games since being taken with the No.4 pick in the 2013 National Draft.
