Western Bulldogs coach Luke Beveridge has defended his decision to name an unchanged line-up for Saturday night's clash with Richmond, despite his side's four-game losing run.

After two wins to start the season, the struggling Dogs have failed to kick more than nine goals in any of their four defeats, and must find a way to prevail against the Tigers at Marvel Stadium to get their campaign back on track.

"We weren't far away from beating Fremantle on their own deck (last week), so even though we're not winning we feel like the team isn't far away," Beveridge told reporters on Friday.

"(We) are definitely playing a stronger game for longer, there's no doubt about that. But we've had a couple of games that we've been pretty disappointed in the consistent output for four quarters.

"But we can't just turn it on its head or flip it over. The VFL team had a tough day at Williamstown last week, there were a couple of boys putting pressure on for spots prior to that and they will get their chance.

"If you're winning every week it would be nice to be picking unchanged sides week to week, but we need to reward that at some point.

"I think some of the lads in the AFL team are definitely feeling some pressure to play well."

The eighth-placed Tigers were forced into making two changes as they look to improve on their 4-2 record.

David Astbury (ankle) and Jack Riewoldt (knee) joined Trent Cotchin (hamstring), Alex Rance (knee), Jack Graham (hamstring) and Shaun Grigg (knee, hip) on the sidelines after last week's win over Melbourne.

The pair were replaced by Shai Bolton and Connor Menadue.

"They've got a similar configuration or composition in their team as we have ... they're not a tall side," Beveridge said.

"They've lost some experienced players, but it's been impressive to see the way some of their young guys have come in and performed.

"I think both teams height-wise won't be far apart, which is a bit different for us. So hopefully we can win some of those and take a couple of bites inside our 50 and be able to hit that scoreboard from those set shots."

Beveridge, who led the Bulldogs to the 2016 premiership in his second year in charge, will coach his 100th AFL match on Saturday night.
