Ciraldo's side have won just one of their last six and are now facing an uphill battle to make the top eight after a 22-16 loss on Saturday night.
Even Tigers coach Benji Marshall conceded his side were "lucky" at CommBank Stadium after Stephen Crichton had a try chalked off in the first half.
But the biggest turning point of the match came in the 55th minute when the Tigers led 16-10 and Canterbury utility forward Josh Curran charged down a Jarome Luai kick and raced in to score.
Curran's try was overturned with replays showing the faintest of touches with Luai's foot.
Marshall said: "I like that we're protecting kickers but I thought we dodged a bullet there to be honest."
And to add to the Bulldogs' woes, the Tigers went down the other end and scored through Jeral Skelton off a Luai grubberkick.
Ciraldo claimed Tigers centre Sunia Turuva was offside in his chase and then impeded Dogs fullback Jacob Kiraz from stopping Skelton.
"I'm sending another email this week and I'll get something written back," Ciraldo said.
"The Josh Curran one, maybe the charge down is gone - his foot did touch him - but Josh charged the ball down first, chasing the kick and then Jarome's foot hit him.
"If that's the way it is, I'll cop that. Jarome clearly didn't think it was a penalty because he turned and chased.
"The more disappointing one was to go down the other end. Someone offside takes out our fullback and then that's a try.
"What's worse? Someone touches your foot or someone takes out your fullback and they score a try."
Ciraldo then pointed to Crichton's try being taken off the Bulldogs late in the first half as another source of frustration.
Canterbury sit 14th after 13 rounds with a 4-8 record and face Parramatta on the King's Birthday public holiday in a match which shapes as make-or-break for their season.
"I think every coach ... we all feel like that, we all feel aggrieved," Ciraldo said.
"What I do know is I've got a very tough football team and what they're going through right now - we've got some injuries - but the guys that are playing, I'm proud of the mental toughness too.
"When those decisions that you're talking about go against us time after time after time, our guys just get on with their job and keep playing tough and represent this club to the best of their ability."
