Multiattack

The death dog makes two Bite attacks.

Bite

_Melee Weapon Attack:_ +4 to hit, reach 5 ft., one target. _Hit:_ 7 (2d4+2) piercing damage. If the target is a creature, it must succeed on a DC 12 CON save or contract a disease. Until the disease is cured, the target is poisoned. Every 24 hours that elapse, the infected creature must repeat the save, reducing its HP maximum by 5 (2d4) on a failure. This reduction lasts until the creature finishes a long rest after the disease is cured. The creature dies if the disease reduces its HP maximum to 0.
