The Manchester City striker will lead the attacking line for the Bosnians in Wednesday night's international friendly with the US in Sarajevo and Everton's Howard knows how much of a handful he can be from their battles in the Premier League.
"There's too many to count, obviously," Howard said of Bosnia's offensive threats. "But I've played a few times against Dzeko and he's always difficult, because he's good left foot, right foot, strong in the air and he can head the ball.
"We won't focus too much on one player, because they've got some really talented players, but we'll keep an eye out for him - he's hard to miss."
Since making his international debut in 2007, Dzeko has scored 29 goals in 53 appearances for Bosnia.
