Dossena received a straight red card in first-half stoppage time at the KC Stadium, being sent off just moments after midfielder Lee Cattermole was also dismissed.
And while Bruce had some sympathy for his former player Cattermole, he had no such sentiment for the Italian.
"I don't know if you can get three red cards but he deserved it," raged Bruce.
"They are the ones that hurt professional footballers. Over the top - a stamp on his ankle. He is lucky, Meyler, that he has got away with it. It could have been an awful situation and it was one of those awful challenges that no one wants to see."
And according to the current laws, Bruce also felt Cattermole deserved to be sent off by referee Andre Marriner.
"In my day it might have been a booking but in this day if you go in with studs showing it's deemed as reckless and is a red card.
"Lee has got to curb that red mist. You can't make that kind of challenge in today's football. He has got to learn that and I'm sure he will eventually."
Even though they were reduced to nine men, Sunderland made life tough for their former boss and could even have pinched a point towards the end of the clash but for a fine save by former Newcastle keeper Steve Harper to deny Adam Johnson.
"To be fair to Sunderland they stuck to a shape, packed the penalty area. We needed a second but we'll take it. It's a big three points for us," Bruce added.
"For Steve to come and make a save - I'm delighted to have brought him here. He's given me a big hand.
"At the end when he needed to make a save he stood big to make that save to spare all our blushes because if we'd missed out on the points there would have been a few sent packing - and me too I would have thought."
In contrast, Sunderland boss Gus Poyet was furious at Marriner's decision to send off Cattermole, while failing to punish Hull's Paul McShane for a challenge that "could have killed" goalkeeper Keiren Westwood.
Poyet accepted Dossena had to go for the stamp on Meyler but felt the eighth red card of Cattermole's career - for a studs up tackle on Ahmed Elmohamady - was a harsh one.
His feeling of injustice was aggravated by the fact McShane was not penalised for his collision with Westwood, which left the Irishman groggy and unable to continue.
Poyet accepted there was no malice in the challenge but gave a colourful account of the danger involved.
Asked about the dismissals, he said: "Cattermole no, Dossena yes.
"I would love the ref to talk. If I was a pundit working today - and I was during the summer when I was out of work - I would ask the technical people to show the tackle on Westwood that nearly cut his head off, the one on Adam Johnson (by Robbie Brady) and the one from Lee Cattermole and let the pundits comment on them.
"They need to comment on all the tackles. I'm not accusing McShane at all: I think he played the ball and he was late but he nearly killed him and he is injured and he is out and I need to change my goalkeeper.
"The tackle of Lee didn't touch him (Elmohamady). He was still on the pitch and he was down for two minutes, there's a little bit of a difference,
"Maybe I'm from another planet, I don't know."
