In this paper, using a bestest little Higgs model (BLHM) approach, we obtain bounds on the top quark electromagnetic and weak dipole moments. These physical observables are sensitive to quantum corrections induced by virtual particles at the one-loop level. The contributions of the virtual particles are obtained from the vertices of scalar bosons, vector bosons, and heavy quarks:

GeV,
