Graham has made 13 appearances this season without finding the net and his lean spell in front of goal stretches back 30 games, for three different clubs, since he struck for Monday night's opponents Swansea in January.
Bruce is becoming fed-up at being asked about Graham's goalless streak but pointed to other strikers who have gone through similar spells and come good recently.
"I keep getting the same thing thrown at me about Danny and he's got to see it through like any other striker," Bruce said.
"Could Swansea be the one that turns him around? We have to wait and see, but you never know.
"We saw something like that the other night when we played Arsenal. Nicklas Bendtner hadn't scored for them for two years, we'd tried a little bit to get him in the summer, I've signed him twice in the past...did Arsene Wenger do it on purpose?
"If he did he's a better genius than I thought he was.
"But all strikers go through it. No matter how good you are, there comes a time in your career when go you go through a lean patch. One thing you've got to do is knuckle down and try not to lose confidence."
Centre-back Curtis Davies admits Graham has been the victim of some well-meaning banter but backed his team-mate for his contribution to their positive start to the season.
"We still give Danny a bit a of stick, a bit of banter, and I think he'd feel uncomfortable if we weren't doing that," Davies said.
"At the same time when we need to gee him up we do. The work he does for us as a team is great, he just needs one to deflect off him and go in the back of the net.
"Maybe the goals aren't coming because he's working too hard for us and he finds himself in positions where he's retreated to help the midfield, not in positions in the box where he can nick the tap-in.
"That's credit to him because he's rolled his sleeves up but I'm sure he'd like a goal too. It would be brilliant for Danny to nick one at Swansea. He's well-liked there and had a very good time there."
