Complaints re noise work in the following way: the council write to the home owner and inform them that a complaint has been received in case they are not aware of the problem. They will then suggest to the complainants that they keep a record of dates and times for say a month and if the nuisance continues the council may install monitoring equipment in a nearby premises which records the noise nuisance and if it proves to be enough of a nuisance (has to be regular and persistent) they can go to court to ask for a noise abatement order on the property. If the owner of the property does not comply then they will be taken to court and fined for causing a nuisance. So as you see it is a long drawn out process, and the owner will be back long before any action is taken. The daughter is not responsible for the noise nuisance, only for the physical care of the dogs which is sufficient in the eyes of the RSPCA i.e. food, water and shelter. I would suggest she carries on feeding the dogs once a day and if she gets no joy from the owner when she returns next week she then needs to decide whether or not to continue, but as a dog owner I suspect she feels sorry for the dogs. As far as kennels are concerned, traditionally most have never expected payment up front, but as many now take payment by cards some are starting to take the card details so they can get their money should the owner not pay up. If the kennels I help at have a long term booking they ask for so many weeks' boarding fees up front especially if its a new customer or a foreigner (a lot dump them when returned home). If the dogs are not collected on the due date the owners have seven days and the kennels can sell or rehome the dogs. IMHO I would mention casually to a person of dishonest intentions that they are away and the dogs are not in the house and sit back and wait to find out they have been burgled - that should bring the owner back.
