My dd lives in a small apartment block. There is a ground level car park and in one corner, there is a small scrubby patch of grass. It’s against the wall and far too small and grim and surrounded by diesel fumes for anyone to use it for anything. With the knowledge and consent of the landlords, my dd and two other dog owners use it for early morning/late night pees. This morning, my dd found a neat pile of squares of dark chocolate in the middle the patch. Obviously it’s freaked her out a bit. Can anyone think of an innocent explanation? And if you were her, what should she do? Obviously she’s shared it on the resident’s WhatsApp. But no replies yet.
