They use their molars for grinding aside from the reduced initially molar m1 (the reduce carnassial) that has advanced for the two chopping and grinding depending upon the canid's dietary adaptation.

Over the decreased carnassial, the trigonid is employed for slicing plus the talonid is useful for grinding. The ratio concerning the trigonid and the talonid indicates a carnivore's dietary routines, with a bigger trigonid indicating a hypercarnivore and a bigger talonid indicating a more omnivorous diet regime.[32][33] Due to its minimal variability, the length of the lower carnassial is used to deliver an estimate of the carnivore's system sizing.[32]
