Annabelle

Keen Hearing and Smell. Annabelle has advantage on Wisdom/Perception checks that rely on hearing or smell.

Pack Tactics. Annabelle has advantage on attack rolls against a creature if at least one of her allies is within 5 feet of the creature and the ally isn't incapacitated.

Retrieve.  Annabelle can retrieve any item smaller than her, movable, and in sight. 

Cuddle. Cuddling Annabelle halves the time needed for rests.

Calming. Calms down  any allies when they are feeling overwhelmed or anxious. Petting her reduces fear, and makes people more likely to want to help you. NPCs will sometimes walk up to the party to pet Annabelle. 

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 1d4 + 2 piercing damage. If the target is a creature, it must succeed on a DC 11 Strength saving throw or be knocked prone.

Tackle and Drag. Melee Weapon Attack: +4 to attack, up to ten feet away, one target. Hit: 5 (2d4+1) knockback damage. Target must succeed a DC 11 strength saving throw or be knocked prone, and then must succeed a DC 11 strength saving throw or be dragged back towards her allies, ten feet. 

Bark. Ranged, Acoustic Attack: +4 to attack, up to ten feet away, up to three targets. Hit:  1 Deafening damage. Targets must succeed a DC 12 Constitution saving throw or be deafened, stunned, and petrified for one round. 

Calming. Deescalate, calm, or pacify:  +4 bonus. Curls up next to, or stands by, a target. Her very presence calms them down, giving them -1 to success for attacking. Touching her gives them -3 to success for attacking. When a target is calmed, persuasion and deception get +3. Intimidation gets -1, due to them already wanting to help. 

Other Dogs/Dog-like creatures: will always attack on sight, regardless of the situation. Anyone in the party can attempt to restrain her, but must make a DC 15 Strength saving check.

Threatening Humanoid: Will growl, and crouch, but not attack unless the other attacks first. 

Loud Noises: Will whimper, and attempt to be near her allies.
