SEN radio host and former Melbourne forward, David Scwarz, says there is disunity among the playing group at the Whitten Oval.

Schwarz said on SEN radio on Monday there is infighting at the club, which is contributing to the side's poor form so far this season.

After shocking the football world winning the premiership last season, the Bulldogs have lost four of their last five games and currently sit ninth on the ladder with a 6-6 record after 12 games.

“There are players down there that aren’t seeing eye-to-eye on a number of issues, and some of them aren’t footy related,” Schwarz said.

“There are other players down there accusing other players of things, whether that be goalkicking or decision-making.

“You go through these things at sporting clubs but it is rare that happens on the back of a premiership given they’ve been so united and so well oiled.

But Schwarz said he expects coach Luke Beveridge to come down hard on the issue and sort out any grievances between players.

“If its personality, and they’re not happy with each other, they’ll sit in a room and work it out or they’ll move one on because they need to fix it.

“Luke Beveridge doesn’t put up with rubbish. So whatever it is, and whoever is expendable, will probably be moved on. They won’t let this linger for too long.”
