Most PWDs, especially those shown in conformation shows, are entirely black, black and white, brown, or silver-tipped; it is common to see white chest spots and white paws or legs on black or brown coated dogs. 'Parti' or 'Irish-marked' coats, with irregular white and black spots, are rare but visually striking. 'Parti' dogs are becoming more common in the United States. However, in Portugal the breed standard does not allow more than 30% white markings. Overall, white is the least common Portuguese Water Dog color, while black with white markings on the chin ('milk chin') and chest is the most common color.
