On the basis of slope-parameter (a') expansion of the dual Born amplitudes, we discuss the renormalization of the dual resonance model in the context of usual quantum field theory. In lowest non-trivial order of a' and in the one-loop approximation, we show that the Veneziano model of general intercept is nonrenormalizable, while the model of unit intercept is renormali.zable. We use the dimensional regularization and 't Hooft's general algorithm in calculating the counter-Lagrangian.
