The origin of charge transport and magnetization anisotropy was studied in ${\mathrm{DyB}}_{12}$, an antiferromagnetic (AF) metal with N\'eel temperature ${T}_{\mathrm{N}}\ensuremath{\approx}16.3$ K that exhibits both small, static Jahn-Teller distortions of the fcc lattice and nanoscale electronic instabilities (dynamic charge stripes). The magnetic field (H) versus temperature (T) phase diagrams were constructed. Moreover, using the angular \ensuremath{\phi} dependences of magnetoresistance and magnetization, butterfly-type patterns of the H-\ensuremath{\phi} magnetic phase diagram in the (110) plane were created, including a number of different magnetic phases separated from each other by radial and circular boundaries. Several positive and negative contributions to magnetoresistance were separated and analyzed, providing arguments in favor of the important role of the spin density wave $5d$ component in the magnetic structure of the antiferromagnetic state. We argue that charge fluctuations in stripes are responsible for the suppression of the Ruderman-Kittel-Kasuya-Yosida indirect exchange between the nearest neighbor $\mathrm{D}{\mathrm{y}}^{3+}$ ions located along the same $\ensuremath{\langle}110\ensuremath{\rangle}$ directions, as these dynamic charge stripes produce the magnetic phase diversity and the butterfly-type anisotropy in ${\mathrm{DyB}}_{12}$.
