I read that earlier and really didn't know what to make of it.
First though was sympathy for the poor dogs suffering in conditions like that, I do hope they recover from their ordeal ...
Second was wondering about the owners state of mind? The dogs were, obviously, being fed & watered, so being 'cared' for in a very basic fashion - I think she just couldn't cope, rather than was being 'cruel'.
It is all conjecture, of course, no improvement of the situation for the animals, for us knowing 'how' or 'why', it happened, just so, so, sad
