Boney Boys (and girls): If the Bone Dog has only 1 hitpoint remaining, it rolls with damage advantage (roll damage then take the higher), then dissipates into dust, leaving nothing behind.
Skeletal Bond: If there is at least 1 skeleton(humanoid) in combat with the Bone Dog, they both gain 1 AC and Advantage on saving throws of all kinds.
(Passive) Bone Chattering: When entering combat solo, the Bone Dog chatters its jaw producing noise enough to alert other nearby Bone Dogs and their Bonded "Masters".

Charging Strike: As a bonus action, if the Bone Dog has used all of its movement this turn, the Bone Dog can do a lunging strike (1d4+4)[10ft +2 to hit]. If this attack hits the target must succeed on a STR/DEX saving throw (DC 12) or be knocked prone.
