Portuguese Water Dog
Summary
The Portuguese Water Dog is a primitive breed that accompanied Portuguese fishermen along the coast of the Algarve and the Alentejo coast for centuries. It was indispensable in tuna fishing traps and on fishing voyages, where it served as an assistant to herd fish schools toward nets, retrieve fishing gear fallen into the sea, carry messages between boats, and as a faithful guard of ships and fishermen's belongings. It is an exceptional swimmer and diver, with full interdigital webbing and a water-resistant coat. In the 1970s, the breed was considered the rarest in the world (Guinness Book of Records, 1981), but it was recovered thanks to dedicated breeders. Today it is internationally known and gained enormous notoriety when President Obama chose two Portuguese Water Dogs for his family during his presidency (2009–2017).

Portuguese Water Dog — Frequently Asked Questions
Are Portuguese Water Dogs hypoallergenic?
Portuguese Water Dogs are considered a low-shedding breed and are often recommended for people with dog allergies. Their curly or wavy single coat sheds very little, which means less dander in the home. However, no dog is truly hypoallergenic — all dogs produce dander, saliva proteins, and urine that can trigger allergic reactions. If you're allergic, spending time with the breed before committing is the only reliable way to assess your individual reaction.
Are Portuguese Water Dogs good family pets?
Portuguese Water Dogs are excellent family pets — they are energetic, playful, and deeply affectionate. They tend to get on well with children and other dogs. Their working dog background means they are adaptable, eager to please, and love being involved in family activities. They need significant exercise and mental stimulation, so they suit active families best. Their low-shedding coat is a bonus for households that prefer less hair.
How much exercise does a Portuguese Water Dog need?
Portuguese Water Dogs need 60–90 minutes of vigorous exercise daily. They were bred as working water dogs — retrieving fishing gear, herding fish, and swimming alongside boats — so they have genuine endurance. They excel at swimming, fetch, agility, and dock diving. Mental stimulation is equally important: they are highly intelligent and will become bored and destructive without regular challenges. A tired Portuguese Water Dog is a well-behaved Portuguese Water Dog.
Are Portuguese Water Dogs easy to train?
Portuguese Water Dogs are highly trainable and eager to please. They are quick learners, food motivated, and enjoy working with their handlers. They respond best to positive reinforcement — they have a sensitive side that means harsh corrections can damage confidence. Early socialisation and puppy classes are recommended. They excel at obedience, agility, water sports, and search and rescue. Their intelligence means they need ongoing mental challenges, not just repetitive basic commands.
What health issues affect Portuguese Water Dogs?
Portuguese Water Dogs have several breed-specific health concerns. Progressive Retinal Atrophy (PRA) — particularly the prcd-PRA variant — can cause vision loss; a DNA test is available. Juvenile Dilated Cardiomyopathy (JDCM) is a fatal heart condition in puppies — DNA testing identifies affected litters. Hip dysplasia and elbow dysplasia can occur. Addison's Disease (adrenal insufficiency) is more common in this breed than average. Responsible breeders DNA test for PRA and JDCM.
How long do Portuguese Water Dogs live?
Portuguese Water Dogs have an average lifespan of 11–13 years. Their working dog constitution contributes to their robustness. Key factors for longevity include good nutrition, regular vigorous exercise, maintaining a healthy weight, dental care, and annual vet check-ups. DNA testing for Juvenile Dilated Cardiomyopathy and PRA in breeding lines is critical — affected dogs often do not live long. Buying from a health-tested breeder dramatically improves the odds of a long, healthy life.
Do Portuguese Water Dogs need a lot of grooming?
Portuguese Water Dogs have a curly or wavy single coat that requires moderate grooming. Unlike double-coated breeds, they don't have heavy seasonal shedding. However, their coat grows continuously and needs trimming every 6–8 weeks by a professional groomer. Brushing 2–3 times per week prevents matts. The traditional "lion clip" (short over the hindquarters, full on the front) or the "retriever clip" (uniform length all over) are both popular options. Without regular grooming, the coat can become matted and uncomfortable.
Are Portuguese Water Dogs good swimmers?
Portuguese Water Dogs are exceptional, natural swimmers — they were literally bred for aquatic work. Their webbed feet, waterproof coat, and powerful build make them ideally suited to water. They love swimming and can retrieve from water for extended periods. Swimming is an excellent, low-impact exercise for them that burns energy without stressing their joints. If you have access to a safe, clean swimming area, a Portuguese Water Dog will happily use it every day. Water play is one of the greatest joys of the breed.
