Sheep usually have fecal matter in their rear wool, and pigs aren't the only animals that enjoy a bath in mud or muddy water when it's hot.
I suspect the ancient jewish idea of cultic purity had less to do with washed skin and hair, and more to do with behaviour and discipline. It's much harder to ritually slaughter a pig than a sheep or cow, and perhaps this was associated with rumination by the early jews.
