Dipolar gases like erbium and dysprosium have a dense spectrum of resonantloss features associated with their strong anisotropic interaction potential.These resonances display various behaviours with density and temperature,implying diverse microscopic properties. Here, we quantitatively investigatethe low-field ($B < 6\,\text{G}$) loss features in ultracold thermal samples of$^{162}$Dy, revealing two- and three-body dominated loss processes. Weinvestigate their temperature dependence and detect a feature compatible with a$d$-wave Fano-Feshbach resonance, which has not been observed before. We alsoanalyse the expansion of the dipolar Bose-Einstein condensate as a function ofthe magnetic field and interpret the changes in size close to the resonanceswith a variation in the scattering length.
