The Geordie defender has put pen to paper on a contract with League One side Wigan Athletic.
He hopes that he can earn a long-term deal, as his present one expires in January.
Dummett told Chronicle Live: "I am 33-years-old now but I know I have a lot of years ahead of me. I don't feel anywhere close to slowing down.
"I know that I still have a lot to offer. It's why I wanted to find the right club. I feel like a young player again in the way that I have to prove myself again and I have no problem with that. When you go to a new club, even though you have played so many times at the top level, you feel like you have to prove yourself again.
"I know that I am now playing for another contract or if Wigan don't keep me I am playing to try to get a new club. I am going there with that ambition to help Wigan and have that same ambition to prove myself."
