He said:'If you don't take advantage in crucial parts of the game, you get punished and that happened to us. We didn't protect our lead. It's all about not switching off.' His counter-attacking side twice had Newcastle rocking, with fine strikes from Ricardo Gardner and Nicky Southall.
Shearer's single-mindedness twice brought Newcastle level. He hammered in from a controversial free-kick and powered past two Bolton defenders to head home a Hughes cross before Bellamy's header won it.
Allardyce and his men were furious at referee David Elleray's decision which brought Shearer's first equaliser. The official penalised goalkeeper Jussi Jaaskelainen for holding on to the ball, but Bolton claimed he was impeded by Shearer. TV pundit AndyTownsend said: 'David Elleray is the greatest nitpicking referee in the game. He spots something like that but doesn't see dangerous tackles. It was a real choker for Bolton. It was a key decision and a poor decision.'
