PWDs come in a number of different colors. Black is the most common color. Sliver tipped, black and white, or brown can also be seen. White chests and legs on black or brown coats are acceptable. “Parti” coats, with white coat and black spots, are rare but they are becoming more popular in the US.
In Portugal the breed standard does not allow more than 30% white markings. White is one of the less-common colors. Their skin has an interesting bluish tinge that is hard to notice underneath the black fur. White varieties have pink skin and are more sensitive to sun exposure than black or brown dogs.
