Yeah, the 'holiday' houses and their part time occupants are not on my favorites list. I see them in the villages and on the roads. Too much money and very little respect for anything except more money.
I know one of the local guys who takes care of the animals (not the dogs) for a couple of the houses.
He has some horror stories about the treatment of the animals. There is a poney at one of the houses. They bought it for their daughter who had a bad case of the 'I wants'. The pony is kept in a shed that is so small it cant turn around in it.

This guy takes the pony out for an hour, or so a day.
