The 28-year-old defender will be in demand in the summer transfer window following West Brom’s relegation to the Championship last season.
He has already received a fine for refusing to go on Darren Moore’s pre-season training camp in Portugal.
Last week, Dawson skipped Albion’s pre-season trip to Portugal, and he has now officially let the club know about his desire to move by submitting a transfer request to the board.
