I play the role of a cleric in a game that also has a ranger.
This ranger happens to have a wolf as a companion. It happened a couple of times that the wolf fell to 0 hp and was declared dead by the DM.
Even though I know that this creature is a beast and it should die once it reaches 0 hp, I can seem to not be bothered by it since I focus on keeping us alive.
I am aware of the Monster And Death section of the book which states that:
Most DMs have a monster die the instant it drops to 0 hit points, rather than having it fall unconscious and make death saving throws.
Mighty villains and special nonplayer characters are common exceptions; the DM might have them fall unconscious and follow the same rule as player characters.
This here is more in the sense of possibility vs a clear rule stating the fact.
I saw nothing about this in the ranger's companion section.
Is there a rule or clarification that I would have missed somewhere? I would like if there was a clear rule or clarification on this somewhere that I would have missed.

Most everywhere I have seen they say RAW, it is DM discretion.
However according to Mike Mearls via Twitter (Twitter conversation), his advice is simply: Yes. They get death saving throws.
