"WebThe formula $$ \sum_{i=1}^3 p_i q_i $$ for the dot product obviously holds for the Cartesian form of the vectors only. The proposed sum of the three products of components isn't even dimensionally correct – the radial coordinates are dimensionful while the angles are dimensionless, so they just can't be added.
