The Portuguese Water Dog, commonly abbreviated as PWD, is a medium-sized, robust working dog built for endurance in the water. Males stand 20 to 23 inches at the shoulder and weigh 42 to 60 pounds, while females measure 17 to 21 inches and weigh 35 to 50 pounds. The overall impression is of a strong, well-muscled dog with substantial bone, capable of sustained physical effort both in water and on land. Nothing about this breed suggests delicacy, yet neither should it appear coarse or lumbering.
The body is slightly longer than tall, creating a rectangular outline when viewed from the side. The chest is broad and deep, reaching to the elbows, with well-sprung ribs that provide ample lung capacity for the diving and swimming work the breed was developed to perform. The topline is level and the back is broad and well-muscled. The loin is short and connects to a croup that falls away slightly. The tuck-up is moderate, contributing to the breed's athletic profile without appearing overly refined.
The head is large and well-proportioned to the body, with a broad skull that is slightly longer than the muzzle. The stop is well-defined. The muzzle is substantial, wider at the base than at the nose, with strong jaws and a scissors or level bite. The nose is broad and fully pigmented, black in dogs with black, white, or black and white coats, and brown in dogs with brown coloring. Eyes are medium-sized, round, and set wide apart, dark brown or black in color, contributing to the breed's attentive and penetrating expression. The ears are set above the line of the eye, heart-shaped, thin, and held close to the head. They are not large relative to the head size.
The tail is an important working feature and is not docked. It is thick at the base, tapering toward the tip, and reaches approximately to the hock. When the dog is attentive, the tail is held in a ring, carried over the back, and the tip should not extend forward of the loin. In the water, the tail functions as a rudder, and its strength and flexibility are essential to the breed's swimming ability.
The coat is the PWD's most distinctive feature and comes in two varieties: wavy and curly. The wavy coat falls in gentle waves with a slight sheen, while the curly variety forms compact, cylindrical curls that are somewhat lusterless. Both coat types are single-coated, meaning there is no undercoat, which significantly reduces shedding and contributes to the breed's reputation as a lower-allergen option for some allergy sufferers. The coat grows continuously and requires regular grooming to prevent matting. Two traditional clips are used: the lion clip, where the hindquarters and muzzle are shaved while the rest of the coat is left at full length, and the retriever clip, where the entire coat is scissored to approximately one inch in length. Acceptable colors include black, white, brown, and combinations of black and white or brown and white.
The front legs are straight and well-muscled with strong pasterns. The feet are flat and somewhat webbed, an essential adaptation for a breed that spent centuries working in water. The webbing between the toes provides propulsion during swimming and contributes to the breed's powerful, efficient stroke. The hindquarters are well-developed and powerful, with well-angulated stifles and strong hocks. Movement is effortless and balanced, with good reach and strong drive. On land, the PWD moves with a lively, ground-covering gait that reflects its working stamina.
Affectionate With Family
★★★★★
PWDs form intense bonds with their families and want to be physically close to their people at all times. Their devotion is genuine and persistent, making them deeply loyal household companions.
Good With Young Children
★★★★☆
PWDs are patient, playful, and sturdy enough for active families with children. Their exuberant greetings may overwhelm very small toddlers, but they are generally gentle and affectionate with kids.
Good With Other Dogs
★★★★☆
PWDs are sociable and enjoy playing with other dogs, particularly those who match their energy. Their mouthy play style may need monitoring, but they are rarely aggressive toward other canines.
Shedding Level
★★☆☆☆
The single coat without undercoat produces significantly less loose hair than most breeds. PWDs are often recommended for allergy-conscious families, though no breed is truly hypoallergenic.
Coat Grooming Frequency
★★★★☆
The continuously growing coat requires brushing every other day for curly varieties and regular professional trimming every four to six weeks. Neglected coats mat quickly and painfully.
Drooling Level
★☆☆☆☆
PWDs are clean-mouthed dogs that produce minimal drool. Owners will not encounter slobber on furniture or clothing under normal circumstances.
Coat Type
★★★★☆
The single coat comes in two varieties: wavy, which falls in gentle waves with a slight sheen, and curly, which forms compact cylindrical curls. Both grow continuously and require regular maintenance.
Openness To Strangers
★★★☆☆
PWDs show brief initial reserve with unfamiliar people before warming up quickly. They are not suspicious or standoffish but take a moment to evaluate new arrivals before offering their characteristic enthusiasm.
Playfulness Level
★★★★★
PWDs are exuberantly playful throughout their lives, bringing boundless enthusiasm to games, water activities, and interactive play. Their energy and joy are infectious and enduring.
Watchdog/Protective Nature
★★★☆☆
PWDs will bark to alert their families to unusual activity but are not primarily protective dogs. Their watchfulness is moderate, and they are more likely to greet an intruder than confront one.
Adaptability Level
★★★★☆
PWDs adapt well to various living situations provided their exercise and companionship needs are met. They handle travel, new environments, and routine changes with the confidence of a seasoned working dog.
Trainability Level
★★★★☆
Intelligent and eager to collaborate, PWDs respond enthusiastically to positive training methods. They learn quickly and retain well, excelling in obedience, water trials, and agility competition.
