I'm sorry but the Boar is pretty much useless most of the time, with a highly situational ability that doesn't work very well.
Meanwhile cat-lovers everywhere aren't getting what we want. A Panther or a Tiger or even a Lion (though I would prefer a Black Panther because I'm partial to them and I think the stat block and abilities would be easy to implement).
Panther

7 (-2)
Skills Perception +4, Stealth +6
Senses passive Perception 14
Challenge 1/4 (50 XP)
Keen Smell. The panther has advantage on Wisdom (Perception) checks that rely on smell.
Pounce. If the panther moves at least 20 ft. straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 12 Strength saving throw or be knocked prone. If the target is prone, the panther can make one bite attack against it as a bonus action.
Actions
Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: (1d6 + 2) piercing damage.
Claw. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: (1d4 + 2) slashing damage.
Way more interesting than the Boar mechanically, way cooler/more fun if you love cats in real life, and it gives us a stealthy animal companion to round things out.
