The summer signing from Queen of the South has been sidelined for a month with rib problem but returned for the second string in Wednesday's 2-0 win against Forest Green ahead of Saturday's clash with Sheffield United
The Swans have failed to score in their last three Championship games and Dobbie hopes to get the opportunity to end their drought.
He told the club's official website "It felt really good (against Forest Green), there is no problem injury wise and it's good to be back.
"I'm ready if the gaffer [Paulo Sousa] needs me. It was only four weeks I was out, the last week and a half I've been doing quite a lot of running so I'm ready.
"That's the main reason I came here, to score goals for Swansea and it was just unfortunate after scoring a few goals I got injured, but if I'm back on Saturday I'll be trying to do that."
