The invention relates to a method for manufacturing a dog ring gear (30), each dog (32) being made up of a front portion and a rear portion, said method including the following steps: forming, by means of compression and sintering, a ring gear with dog preforms (50) extending on all or part of the periphery thereof; and calibrating the sintered ring gear in a die including a front die half (64) and a rear die half (62), intended for engaging at the junction between the front and rear portions of the dogs, the thickness (A) of a rear portion (BP) of each preform, in the original plane of the dogs, being greater than the narrowest section (S1) of a groove (66) formed in the rear die half and smaller than the thickest section (S2) of said groove, in said plane.
