The former Sheffield United and Barnsley hitman sparkled for the Millers as they snatched a late win away to League Two basement boys Wrexham at the Racecourse Ground.
And although it was substitute Chris O'Grady who won it for the visitors with a 78th-minute strike, Dyer was at the heart of his team's best attacking moves.
"I though Bruce did really well, he's wily," praised Robins. "He was cute and used all of his experience. Around the box he held the ball up, got his body stuck in and created one or two openings for us without being dynamic.
"Someone like Bruce is always involved in the game. He's great around the edge of the box, his twisting and turning brings other people into play, which helps us out.
"I've got no doubt he will score while he's here with us. Bringing Bruce in will give some people a kick up the backside."
Victory saw Robins' team move up to tenth in the table - and there was also praise for match-winner O'Grady and experienced shot-stopper Andy Warrington
"We needed an injection of fresh blood and that's what we got off (Marc) Newsham and O'Grady when they came on," added Robins.
"And Andy's used all of his experience to save that one (free-kick) at the end, he's got across his goal really well. He's a good goalkeeper."
Defender Ian Sharps (hamstring) was unfit to start, but Robins is hopeful the former Tranmere Rovers centre-back should be back to full fitness soon.
"It's been only nine or ten days since he injured his hamstring, so we'll see how he is this week.
"We've just got to keep working hard now after this result. All these games in this division are all the same, they're all hard.
n Meanwhile, Brian Laws remained defiant but admitted it was a "big week" as Sheffield Wednesday face two successive home games as they look to turn results around.
The Owls manager - who has overseen the worst league start in the club's history, five straight defeats - has issued a "Don't panic" warning.
But he knows that results have to improve and quickly .
n Millers: P24/25
