Luke Beveridge has declared his side is the playing its best football in his time as coach as the Western Bulldogs prepare for Saturday's preliminary final against Greater Western Sydney.

Wins over West Coast and reigning premier Hawthorn in the first two weeks of the finals has instilled a confidence within the playing group as they get ready for the interstate trip to Spotless Stadium.

"We have had some big outcomes on our recent journey that added fuel to the fire, but you'd have to consider the last two weeks the biggest performances since I've been here," Beveridge said on Thursday.

"Because they're big games, you'd have to consider it's (our) best footy."

While the end of season bye helped the Bulldogs get key players fit for the finals, Beveridge was unsure whether the Dogs would have an advantage over GWS, who have had two weeks off in the past month.

The Giants bypassed semi-final weekend after accounting for their crosstown rival the Swans in week one of the finals and progressed straight to the penultimate weekend of the season in their first ever finals series.

"We've got a bit of continuity because we've only had the one break, but time will tell," Beveridge said.

"It's a combination of so many things. It's the maturity of your group, the need for games under your belt, how sore your players have been and all those sorts of things.'

“I'm sure the opposition have trained in a fashion that's prepared them well for Saturday.

“There are just no excuses (for) either side."

Having put the heat on his defenders to curtail the Hawthorn's dangerous small forwards ahead of the semi-final, Beveridge is now calling on another commanding performance for his deep midfield against the Giants.

In their two final wins, the Dogs smashed the Eagles and Hawks in both contested and uncontested possession, but the Giants are just as proficient in those key areas.

"I think our midfield over the last two weeks have dominated the games in a really even spread," Beveridge said.

"If we can get that again it's going to really help us.

"I think it's quite a common thing to want midfield dominance, but it doesn't necessarily win you the game.

"You've got to get it done on the scoreboard and defend well, but I think it's going to have a big say again."
