Dudfield has played four times so far for the Cobblers, and said: "I love it at Northampton."
The 22-year-old forward has been unable to hold down a first team place in Peter Taylor's side, and is enjoying the change.
"It's a battle here at the moment but it's part and parcel of coming on loan to a struggling team.
"There are a lot of teams I could be on loan with where there is nothing to play for, but there is everything to play for here and I just want to make sure I play well and that we stay up.
"Then hopefully I can get something sorted because I would like to stay at the club," he added.
