Friday I had a complaint from animal control saying my dog doesn't have the proper shelter he needs?

but he does I was just washing it out. I was watching my dog and I've lived in my residence for over a year now and never had a complaint from a neighbor until a new neighbor appears. I was outsidethis evening and saw her and her husband watching through the window at my dog. the animal control officer said that the person who reported me also said that theynever see us feed or water the dog which is NOT true at all and the officer agreed and said the dog looked very healthy is this slander? what can I do about it?
