In Pr-substituted NdOs$_4$Sb$_{12}$ ($x \\le$ 0.75), but not in NdOs$_4$Sb$_{12}$, Clogston-Jaccarino plots of $\\mu^+$ Knight shift~$K$ versus magnetic susceptibility~$\\chi$ exhibit an anomalous saturation of $K(\\chi)$ at $\\sim-$0.5% for large susceptibilities (low temperatures), indicating a reduction of the coupling strength between $\\mu^+$ spins and $4f$ paramagnetism for temperatures $\\lesssim$ 15~K.
