Poor creature has been whining more than usual for 24 hours now and there's no sign of people being home. We don't really know them except to occasionally say hello in the street - a woman and her adult son live there, woman is a nurse and sometimes works away, don't know what son does.
The dog lives in the garden (in a kennel) and gets no fuss or walks ever. I WFH twice a week and am usually here at weekends, plus I was a SAHM before that and never saw any contact.
I've called the local police/RSPCA and they both say there's nothing they can do right now - if the dog is housed and not visibly starving then it's 'fine' 
Will I be in any legal trouble if I lower a bowl of food over the fence for him?
I may already have done this.
