The dog looked well cared for to me, but had been incontinent for some days beforehand - I think that the fly eggs had been laid then perhaps. That and the flat was infested with flies (much like the local hospital) so it wouldn't have taken maggots long to find the body. The flies have been troubling the area for over a week now - for some reason there is a plague of them, so the presence of these wasn't unexpected. Except that there was little being done in the flat to control them (hence the vulnerable adult form) Dogs can become 'stiff' pretty much immediately after death, not true 'rigor' but something similar. The dog wasn't malnourished - if anything it was a bit tubby. The woman also had some other animals in the flat and they were all in good condition so there was no cause for concern in my eyes - otherwise, you can trust me, I would have told the RSPCA
