Well my dog is not usually a thief but I forgot I had cut a lemon in half and left it in a place he could reach.  Popped upstairs to do some cleaning and when I got back he's chewed it and eaten all the juice . 
Is it likely to do him harm (I am prepared for any explosions that may happen overnight :-D)?  He seems totally fine at the minute.
Wish I'd have seen his face when he had a mouthful of sour lemon juice!!

Don't think it will do him any harm two of my girls love honey & lemon if we have a cold they sit & beg for some

I don't think it will harm him but I suppose it might make him a bit loose as they are very acidic.  Silly dog :-)

It shouldn't harm him no, but I am amazed he has eaten a lemon!  I usually put cut lemons on the work tops when I am preparing food so that my dog doesn't steal anything more tasty, a lemon near his nose usually works :)

Well he seems fine today!  Wonder what was going through his head to make him decide to steal that?

Greed? :-D

He's probably the least greedy dog ever!  But he's very nosy and perhaps a tad stupid :-D
