Bendtner will wait until after this summer's European Championships before deciding his long-term future.
"I haven't given it much thought," Bendtner told The Shields Gazette. "I really like the club and the manager has done really well since he came in here, but I haven't given it any thought yet.
"I still have two years left with Arsenal. It isn't just up to me.
"Ideally it would only be in my hands, but I'm just waiting to see in the summer.
"We've got the Euros, then in the summer after the Euros, we will see where we are."
