The interaction of mesons with electromagnetism is often well described by the concept of vector-meson dominance (VMD). However, there are also examples where VMD fails. A simple chiral Lagrangian for pions, rho and omega mesons is presented which can account for the respective agreement and disagreement between VMD and phenomenology in the sector of light mesons.
