while it's not something we would ever have done with our dog, some dogs are far happier in their own homes with someone popping in to feed and water them, than being put into kennels where they can become very stressed.
if you're very concerned, and if the wimpering and whining (barking?) is a realy nuisance to you,why not have a word with the person who comes round to feed it, next time you see them, and find out exactly what's going on before you think about taking it any further.
