@JeremyECrawford When wearing barding (PHB p. 155), do animals need proficiency in that type of armor to avoid penalties(PHB p. 144)? #DnD

The rule on monsters and armor is purposefully generous and is ultimately in the DM's hands. See MM p. 9. #DnD https://t.co/1UQlGYnPZY

That would be monsters. What about animals? I bought a flying monkey which I gave barding. Does it now have Disadvantage on everything?
