The head coach says the Championship club are close to finalising a new contract with skipper and centre-back Hudson.
And Wagner says Town intend to take up the extra year option on midfielder Hogg’s deal, which runs out this summer.
Hudson is set for a 38th appearance of the campaign at Rotherham United on Tuesday evening, when a Town win will banish any mathematical chance of relegation.
Former Watford man Hogg remains on the comeback trail from a knee injury, and Wagner hopes he will play a part between now and the final match at home to Brentford on May 7.
“I am very happy with Hoggy and we will take up the option of another year,” said Wagner, whose side are 16th after winning 2-0 at Blackburn Rovers on Saturday.
“With Huddy, we have had good talks, there are just a few little things to sort out. Like in life, if both partners are happy, they will be together.”
Rotherham are unbeaten in nine under former Town boss Warnock and are nine points clear of the drop zone.
“They have found a way forward and it looks like the manager has found a style which suits the players,” said Wagner, who has a question mark against forward Jamie Paterson (hamstring).
“Rotherham keep things simple and they are playing with confidence. If a side consistently collect points like they have, then you have to say they deserve them - it’s not down to luck.

“It is up to us to go there and stop their run, to show hunger and a desire to develop what has been a good start to a busy week (Town host Birmingham City on Saturday).
“In our job, nothing feels better than winning.
“There are 12 points left to play for and we want to get as many as we possibly can.”
