Dogs. I have had multiple dogs that really want alcohol. Ones that are otherwise well behaved about not stealing human food/drink when it is left where they can get it that will absolutely take beer and/or mixed drinks not only if you leave the room, but if you turn your back on them while in the same room.
I’m very sure it isn’t at all good for them, so now I take extra care when I have such drinks (to take them with me, or finish them, or put anything open back in the fridge).
