We are using this rug in our mudroom.  It does not slip around at all on the marmoleum floor without a pad.  It gives a cheery, fun feeling to the entry.  The background is a swirl pattern that I don't think will show much dirt.  We track in a lot of snow on our boots etc.   Ours is the 3x5 and each bird measure about a foot.  Have only had the rug for two weeks, and will probably wash it and hang to dry and store at the end of winter.  Very happy with this purchase.
