We keep a small selection of little doggie necessities at Aunty Biscuits.  She is responsible for washing them, repairing them,stock levels etc.  One of the mats we paddle over into the kitchen was turquoise with white spots, which doesn't show the dirt as badly as it sounds it should be.  Another is a red fleece coat which has been washed several times.  This time they shared a wash.  We now have a mat that is turquoise with a very, very delicate shade of pink.  Good job she likes pink.
