Alexis Sanchez equalised three minutes later but Arsenal suffered a blow when goalkeeper Petr Cech went off injured.
Albion restored their lead on 55 minutes when Hal Robson-Kanu prodded in a minute after coming on and, after Danny Welbeck had struck the bar for Arsenal, Dawson struck again with a header from James McClean's corner.
