Western Bulldogs youngster Mitch Wallis says their AFL win over Hawthorn felt so good he needed reminding it was just the pre-season.

The Dogs' comeback victory last Friday night, their first of any kind since June last year, has transformed the mood at the club.

"It's been a while since our last win, eight or nine months, so to get that feeling again gives us confidence," Wallis told reporters on Tuesday.

"Training this week's been great so far just with how we feel and how we're going about it.

"We've got lots of confidence leading into this game on Saturday."

It has renewed the Bulldogs' belief they are making progress, after ending last season with 11 straight defeats.

Making it even sweeter was the fact they came from behind late in the game, the reverse of their many fade-outs last year.

"If you had have watched the vision, I went up after the game, I was pretty excited," Wallis said.

"But then I sort of got brought back to reality that it is a practice match.

"But I'm still passionate about winning, I've only had a few so every one counts."

Wallis has played in just six wins in his two AFL seasons.

The Bulldogs next face Fremantle in the West Australian town of Mandurah on Saturday in what are forecast to be mid-30s temperatures.

But they're confident the weather won't be a problem given they've spent the summer training in similar conditions.
