Portuguese Water Dog: The Obama Effect

The Portuguese Water Dog is a medium-sized, non-shedding working dog from Portugal that became one of the most talked-about breeds in the world when President Barack Obama's family chose one, named Bo, as the First Dog in 2009, followed by a second Portie, Sunny, in 2013. The White House connection generated enormous public interest in a breed that was previously known primarily to dedicated enthusiasts.

But the Portuguese Water Dog's qualities extend far beyond its celebrity moment: this is a genuine, hardworking, highly capable breed with a long and fascinating maritime history.

Origins: Portuguese Fishermen and the Atlantic

The Portuguese Water Dog has been a working companion to Portuguese fishermen for centuries. The breed was used by the fishing communities of the Algarve (southern Portugal) and later across the entire Portuguese coast in a variety of tasks that made it an indispensable member of the fishing crew:

• Herding fish into nets by swimming around schools and driving them toward the boat
• Retrieving fishing gear, tackle and lines that fell overboard
• Swimming between boats to carry messages and items

The Portuguese name for the breed, Cao de Agua (literally "dog of water"), reflects these working roles directly. The breed's physical characteristics are precisely suited to this work: a robust, muscular, waterproof-coated body capable of diving and sustained swimming in Atlantic conditions.

The breed nearly vanished in the 20th century as mechanized fishing replaced traditional methods and the need for working water dogs declined. By the 1930s, the breed's population had fallen to near-extinction.

Vasco Bensaude, a wealthy Portuguese shipping magnate, became the key figure in saving the breed, he sought out fishermen's dogs for a breeding program to re-establish the breed.

The Portuguese Water Dog Club of America was formed in 1972, and the breed's profile grew in the United States, but the Obama family's selection in 2009 created an unprecedented spike in public awareness.

Physical Characteristics

The Portuguese Water Dog is a well-proportioned, robustly built working dog of medium size, neither too large to be agile in a boat nor too small to have the strength and stamina for sustained water work. Its most notable feature is its coat, available in wavy or curly varieties and usually worn in a lion clip (hindquarters, muzzle and base of the tail shaved, the rest left full length) or a retriever clip (about one inch long, evenly over the body).

Physical Characteristic	Males	Females
Height	50-57 cm (20-22 in)	43-52 cm (17-20 in)
Weight	19-25 kg (42-55 lbs)	16-22 kg (35-49 lbs)
Build	Robust, muscular, well-proportioned
Coat	Wavy or curly; single layer; waterproof	Same
Coat colors	Black, white, brown, black with white, brown with white	Same
Eyes	Medium-sized; black or brown; well-set	Same
Tail	Thick at base, tapering; carried in a curve above the topline	Same
Feet	Webbed, primary swimming adaptation	Same

The Portuguese Water Dog's coat is a single layer with no undercoat, this is the basis for its classification as a low-shedding breed. Like the Poodle (a related breed sharing similar water-retrieval origins), the PWD's coat grows continuously and requires regular trimming rather than seasonal shedding. Its coat is tolerated well by many people with dog allergies, although no dog breed is truly hypoallergenic.

The Obama Effect: Boom and Responsible Breeding

When Bo Obama arrived at the White House in April 2009, the Portuguese Water Dog instantly became one of the most sought-after breeds in America. The breed went from relative obscurity to household name.

The Obama situation illustrates a pattern that repeats with celebrity breeds throughout history: a sudden spike in demand rewards irresponsible breeders who produce puppies quickly without health testing or temperament selection, buyers make impulsive decisions and the breed's welfare suffers.

The most important message for anyone interested in a PWD because of the Obama dogs: choose a breeder who health-tests for PRA, JDCM and GM1 gangliosidosis, has OFA hip certification and participates in breed club health programs.

Temperament

The Portuguese Water Dog is an athletic, intelligent and deeply people-oriented working dog. These are dogs that were bred to work closely with fishermen, taking direction, swimming long distances on command, responding reliably to signals in noisy, difficult maritime conditions.

The behavioral profile that successful working water dogs required maps directly to the companion dog temperament that PWD owners describe today: responsive, energetic, playful, biddable and strongly bonded to their people.

PWDs are energetic and need substantial daily exercise, but they are also tractable and manageable in the home when their needs are met. They are excellent with children, sociable with strangers when well-socialized, and typically fine with other dogs.

Health: Progressive Retinal Atrophy (PRA)

Progressive Retinal Atrophy in the PRCD form is present in Portuguese Water Dogs and represents a significant breeding concern. The PRCD-PRA mutation causes progressive degeneration of the retinal photoreceptors, leading to night blindness followed by complete blindness. A DNA test (OptiGen PRCD test) is commercially available.

Responsible breeders test all breeding stock. Mating two carriers produces 25% affected offspring. Mating a clear dog with a carrier produces 50% carriers (which do not develop the disease) and 50% clear dogs, no affected offspring.

Health Condition	Prevalence/Notes	Screening
Progressive retinal atrophy (PRCD)	Present	DNA test available
Juvenile dilated cardiomyopathy (JDCM)	Fatal, puppies; DNA test critical	DNA test available
GM1 gangliosidosis	Fatal storage disease	DNA test available
Hip dysplasia	Reported	OFA/BVA X-ray
Follicular dysplasia (improper coat)	Reported	Visual
Storage disease (other forms)	Reported	DNA screening

Health: Juvenile Dilated Cardiomyopathy (JDCM)

Juvenile dilated cardiomyopathy is one of the most devastating inherited diseases in the Portuguese Water Dog, a fatal cardiac condition that affects puppies between approximately 6 weeks and 7 months of age. Affected puppies develop sudden cardiac failure and die quickly, there is no effective treatment. The disease is caused by a homozygous mutation (two copies needed to produce an affected dog).

A DNA test is available and is one of the most critical health tests for PWD breeders. By testing all breeding stock and never mating two carriers, breeders can completely prevent the birth of affected puppies. This test is essential, it is not optional for responsible breeders.

Health: GM1 Gangliosidosis

GM1 gangliosidosis is a lysosomal storage disease, a condition in which a critical enzyme (beta-galactosidase) is absent or deficient, causing abnormal accumulation of lipid materials (gangliosides) in nerve cells. Affected Portuguese Water Dog puppies develop progressive neurological deterioration starting at approximately 6 months, including ataxia, visual impairment and behavioral changes, progressing to total disability and death.

The disease is autosomal recessive, a DNA test is available. Responsible breeders test all breeding stock. As with JDCM, testing can completely prevent the production of affected dogs. For health and vaccination guidance see Dog Vaccination Schedule Explained.

Exercise and Activity Requirements

The Portuguese Water Dog is an athletic, energetic breed that needs substantial daily exercise. Adults require substantial daily activity. Swimming is particularly natural and ideal for the breed, they are typically enthusiastic and capable swimmers from a young age. Hiking, agility, obedience and working retriever trials are all well-suited to the breed's capabilities.

For exercise guidance see Exercise Needs by Dog Breed and Portuguese Water Dog Care Guide. For comparison with related water-working retrievers see Labrador Retriever. For allergy-related breed comparisons see Best Dogs for Allergy Sufferers.

Coat Care

The Portuguese Water Dog's single-layer, continuously growing coat requires regular professional grooming, typically about every two months for trimming, with brushing every other day. The traditional working clips, the lion clip (muzzle and hindquarters shaved) and the retriever clip (coat trimmed to about one inch over the body), are both acceptable for pet and show dogs.

Despite the low-shedding characteristic, the coat does require significant maintenance.

Summary

The Portuguese Water Dog is a breed of genuine working heritage, extraordinary swimming ability and an adaptable, intelligent companion temperament. Its association with the Obama White House brought it deserved fame. The most critical health screenings are DNA testing for JDCM and GM1 gangliosidosis, both fatal diseases that can be entirely eliminated through responsible breeding.

PRA DNA testing and OFA hip certification are also essential. For active families or individuals who can meet its exercise needs and maintain its coat, the PWD is an exceptional companion.
