Multiattack

The temple dog makes two Bite attacks. If both attacks hit a Medium or smaller target, the temple dog sinks in its teeth, shaking its head violently, and the target must succeed on a DC 15 Strength saving throw or take 9 (2d8) slashing damage and be grappled (escape DC 15). Until this grapple ends, the target is restrained, and temple dog can't Bite another target.

Bite

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) piercing damage plus 7 (2d6) radiant damage.
