Like Poodles and several other water dog breeds, PWDs are highly intelligent, can have curly coats, have webbed toes for swimming, and do not shed.[6] However, Portuguese Water Dogs are more robustly built, with stout legs, and can have a wavy coat instead of tightly curled. If comparing the structure to that of a Poodle, there are significant differences between the two breeds. The Portuguese Wat
er Dog built of strong substantial bone; well developed, neither refined nor coarse, and a solidly built, muscular body. The Portuguese Water Dog is off-square, slightly longer than tall when measured from prosternum to rearmost point of the buttocks, and from withers to ground. Portuguese Water Dog eyes are black or various tones of brown, and their coats can be black, brown, black and white or brown and white. Male Portuguese Water Dogs usually grow to be about 20 to 23 inches (51 cm to 58 cm) tall, and they weigh between 40 and 60 pounds (18 kg to 27 kg), while the females usually grow to be about 17 to 21 inches (43 cm to 53 cm) tall, and they weigh between 35 and 50 pounds. PWDs have a single-layered coat that does not shed[7] (see Moult), and therefore their presence is tolerated extremely well among many people who suffer from dog allergies. Some call PWDs hypoallergenic dogs, but any person with dog allergies who would like a dog with these qualities should actually spend time with the animals before purchasing, to test whether the dog is truly non-allergenic to them. 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 combination.
