Despite recent injuries, Dawes is confident world record holder Bolt will be in peak condition as he attempts to retain both individual titles and help Jamaica keep their 4 x 100m crown.
"He's back fully," Dawes said. "He has been training very, very hard and his performance is on track.
"We expect he'll be fully fit by the time the Olympics come around."
Dawes believes Bolt and sprint rival Yohan Blake could reach new heights in London for the Jamaican team.
"Both of them are at the top of their game.
"If the conditions are ideal, then we are going to see something fantastic. We may see records go.
"They are 100% fit and 100% raring to go. They are mentally fit and they are going to be going all out."
First up for Bolt will be the men's 100m's on 4 August in the Olympic Stadium, with his defence of the 200m title starting three days later on 7 August. The men's 4 x 100m Relay starts on 10 August.
