The Wembley play-off final hero played a significant part in getting Swansea to the Premier League and is keen to prove his worth to the club again.
"The whole point of playing football is to get to the highest league and I did that with Swansea," said Dobbie, signed on a free transfer from Queen of the South in 2009.
"The season we got promoted to the Premier League I thought I was given a fair crack and I showed the fans what I can do.
"Then I kind of got isolated last year. But I've come back fit and hungry to show the manager I deserve a part in this team."
