The Bulldogs said the decision was made on the back of internal talks and that the club would support the 27-year-old, who also took time off due to personal reasons in July 2020.
“Lachie has been dealing with some personal issues for a period of time,” said Bulldogs head of football Chris Grant.
“After some recent internal discussions, it has been determined and agreed with Lachie that the best course of action is for him to spend some time away from the club while he addresses his personal issues.
“We will continue to support Lachie during his leave of absence, with his personal wellbeing the sole focus for everyone in the immediate term.
“During this period of absence from the football program Lachie will not play at either AFL or VFL level.
“We expect that Lachie’s privacy will be respected during this period.”
Hunter has played 167 AFL games since landing at the Bulldogs via the 2012 national draft.
The former Bulldogs vice-captain has played four of five senior matches this season.
