Portuguese Water Dog
Bred along Portugal's coast to herd fish into nets and retrieve gear from the sea, this curly-coated working dog is intelligent, athletic and famously low-shedding. Keen, trainable and loves water. It suits active owners who can provide plenty of exercise and mental work and keep up with the regular grooming a non-shedding curly coat demands.
Portuguese Water Dog scorecard
Overview
The Portuguese Water Dog is a medium-sized, athletic working breed with a distinctive curly or wavy single coat and a deep love of the water. Standing roughly 43–58cm at the shoulder and weighing around 16–27kg, it was bred along the coast of Portugal to be a fisherman's all-purpose helper — diving for tackle, retrieving lost gear and carrying messages between boats. That heritage shows in everything about the dog: it is strong, tireless, quick to learn and genuinely happiest when it has a job to do and a person to do it with.
In a modern home the Portuguese Water Dog is best understood as a high-energy, highly trainable companion rather than a laid-back pet. It is affectionate and people-focused, often forming a close bond with its family and disliking long spells alone. The low-shedding coat has made the breed popular with allergy-conscious owners, but no dog is truly hypoallergenic, and the coat's grooming demands are real. For an active household that can commit to daily exercise, training and regular coat care, this is a rewarding, characterful dog.
Good to know — a Portuguese Water Dog is best with a garden and manageable for committed beginners. Every dog is an individual, so meet a few and chat to a good breeder or rescue before deciding.

History & origins
The breed developed over centuries along Portugal's Algarve coast, where it worked alongside fishermen herding fish into nets, retrieving items from the sea and acting as a swimming courier. Its Portuguese name, Cão de Água, simply means "dog of water." As industrialised fishing reduced the need for working sea dogs, the breed declined sharply and by the early twentieth century was close to disappearing.
A Portuguese shipping magnate, Vasco Bensaúde, is widely credited with rescuing the breed from near-extinction in the 1930s by gathering surviving working dogs and establishing a breeding programme. The Portuguese Water Dog was later recognised by the Fédération Cynologique Internationale and the UK Kennel Club, and gained wider public attention internationally in the twenty-first century, including after a dog of the breed lived at the United States White House. It remains a relatively uncommon breed in the UK.
Temperament & family fit
Portuguese Water Dogs are bright, biddable and emotionally connected to their people. They tend to be loyal and demonstrative within the family, and many are good-natured with children and other dogs when raised and socialised well. Their working background gives them strong problem-solving instincts and a degree of independence — they think for themselves, which is a delight when channelled and a nuisance when bored.
This is not a breed that suits being left for long hours. Under-exercised or under-stimulated individuals can become restless, vocal or destructive, and some develop a strong attachment that tips into separation distress. They are generally watchful without being aggressive, and many will bark to announce visitors. With consistent leadership, plenty to do and lots of human company, the Portuguese Water Dog is an enthusiastic, fun-loving and devoted companion.
- Families with children of all ages
- Owners ready for consistent training
- Homes with a secure garden
Training & intelligence
Few breeds are as rewarding to train. Portuguese Water Dogs are intelligent and eager to please, and they excel in obedience, agility, scent work, dock diving and assistance-style tasks. Reward-based, positive-reinforcement methods work best; the breed responds poorly to harsh handling and thrives on variety and praise. Early, ongoing socialisation with people, dogs and everyday situations helps produce a confident, settled adult.
Because they learn quickly, they can also pick up unwanted habits just as fast, so consistency matters. Owners should plan to keep training fresh and challenging throughout the dog's life rather than stopping after puppy classes. Mental work — puzzle feeders, trick training, water retrieves — is as important as physical exercise in keeping this clever breed satisfied and well behaved.
- Start socialisation & handling early
- Reward-based methods only — no harsh corrections
- Channel energy into training games & enrichment
Exercise needs
A healthy adult Portuguese Water Dog typically needs 90 minutes to 2 hours a day (roughly 90–120 minutes), split across walks, play and a little training. Higher-energy dogs also need their brains tired — sniffy walks, training games and puzzle feeding go a long way. Puppies, seniors and dogs with health conditions need adjusted amounts — check with your vet.
Grooming & coat
The Portuguese Water Dog has a profuse, non-shedding single coat that can be wavy or curly, and it does not moult in the usual way. This means it needs regular brushing to prevent matting and professional clipping or scissoring roughly every six to eight weeks. The traditional "lion clip" and the "retriever clip" are both seen. Owners should also check and clean ears regularly, particularly given the breed's love of swimming, and keep nails trimmed. The grooming commitment is significant and is a key consideration before buying.
- Brush several times a week
- Bathe every few weeks or as needed
- Check ears, nails and teeth weekly
Feeding a Portuguese Water Dog
Feed a complete, good-quality diet appropriate to the dog's age, size and high activity level, following the manufacturer's guidelines and adjusting to keep the dog lean. Active working-type breeds benefit from food that supports sustained energy and joint health. Because the breed is athletic and food-motivated, it is easy to overfeed treats during training, so factor those into the daily ration. As with all dogs, fresh water should always be available, and any sudden diet changes should be made gradually.
A medium breed
An adult Portuguese Water Dog typically weighs 16–27kg, so a healthy Portuguese Water Dog eats a moderate amount compared with other breeds. Every feeding guide on a bag is written per kilo of body weight, not per breed — start there, then adjust to the dog in front of you.
Life stage
A medium breed is usually done growing at ~12 months, which is roughly when a puppy food has finished its job. With a typical lifespan of 11–13 years, there is a long adult stretch in the middle; switch to a senior food when your vet thinks it is worth it rather than on a birthday.
A high-energy dog eats like one
Portuguese Water Dogs sit at the top end for energy, and a dog working through an hour and a half of real exercise a day burns through the feeding guide faster than a dog on a short stroll. Feed to the dog's condition, not to the middle of the range on the bag.
How much should a Portuguese Water Dog weigh?
Adult 16–27kgfully grown at ~12 months
| Age | Stage | Typical weight | Of adult size |
|---|---|---|---|
| 8 weeks | Just home | 2.5–4.2 kg | 15% |
| 3 months | Young puppy | 4–6.8 kg | 25% |
| 6 months | Growing fast | 8–13.5 kg | 50% |
| ~12 months | Fully grown | 16–27 kg | 100% |
A guide, from the same rule of thumb our puppy growth predictor uses — each age is that share of the way to maturity for a medium breed. Puppies grow fastest early, so a real puppy usually sits a little above the middle rows. Weigh yours and ask your vet if the number worries you.

The Portuguese Water Dog is generally a healthy, hardy breed with a typical lifespan of around 11–13 years, but like all pedigree dogs it has some known inherited conditions for which responsible breeders test. Buyers in the UK should look for breeders who follow Kennel Club and breed-club health-screening recommendations, including eye testing and hip scoring, and who can provide DNA test results for the genetic disorders known in the breed.
Keeping the dog at a healthy weight, maintaining good ear care (especially after swimming), and keeping up with routine veterinary checks, vaccinations and parasite control all support a long, active life. Prospective owners should discuss current health-testing requirements with the breeder and with their vet, and consider insurance given the potential cost of treating inherited conditions.
Common health conditions to be aware of
- Hip dysplasia — a developmental joint condition; breeding stock should be hip-scored under the BVA/KC scheme.
- Progressive retinal atrophy (PRA) — an inherited eye disease causing gradual sight loss; DNA tests are available and used by responsible breeders.
- GM1 gangliosidosis — a serious inherited storage disorder seen in the breed; DNA testing allows carriers to be identified and avoided in matings.
- Juvenile dilated cardiomyopathy — a heart-muscle condition affecting some young Portuguese Water Dogs; discuss screening with the breeder.
- Ear infections — the dense coat and frequent swimming can predispose to ear problems, so regular ear care is important.
- Improper coat / follicular dysplasia — coat and skin abnormalities reported in the breed.
These reflect typical, size- and coat-related risks for dogs like the Portuguese Water Dog; individual breeds carry their own predispositions. Always buy from health-tested parents and speak to your vet — this isn't a diagnosis.

Bringing home a Portuguese Water Dog puppy
Puppies need controlled exercise (a rough guide is five minutes per month of age, twice a day) to protect growing joints, little-and-often meals of a complete puppy food, early socialisation, and a calm routine for toilet training and sleep. Book first vaccinations, microchipping and a vet check early.

Frequently asked questions
How big does a Portuguese Water Dog get?
The Portuguese Water Dog is a medium-sized, athletic breed, standing roughly 43–58cm at the shoulder and weighing around 16–27kg when fully grown. Males are typically larger than females. It has a strong, sturdy build reflecting its working heritage as a fisherman's helper along the Portuguese coast.
Are Portuguese Water Dogs hypoallergenic?
The breed has a low-shedding, single curly or wavy coat that does not moult in the usual way, which has made it popular with allergy-conscious owners. However, no dog is truly hypoallergenic, as allergens come from dander and saliva as well as hair. Allergy sufferers should spend time with the specific dog before committing.
What is the temperament of a Portuguese Water Dog?
Portuguese Water Dogs are bright, biddable and emotionally connected to their people. They are loyal and affectionate within the family, often good-natured with children and other dogs when well socialised, and naturally watchful without being aggressive. Their working background gives them strong problem-solving instincts and some independence, so they think for themselves.
How much exercise does a Portuguese Water Dog need?
This is a genuinely athletic breed needing substantial daily exercise — typically well over an hour combining walks, off-lead running and, ideally, swimming. Most important is engagement: they want to be doing something with you. Activities that work body and brain, such as fetch, agility or water retrieves, suit them best and prevent boredom-driven behaviours.
How much grooming does a Portuguese Water Dog need?
The grooming commitment is significant. The profuse single coat needs regular brushing to prevent matting and professional clipping or scissoring roughly every six to eight weeks, often in the traditional lion clip or retriever clip. Ears should be checked and cleaned regularly, especially given the breed's love of swimming, and nails kept trimmed.
Are Portuguese Water Dogs good family pets?
They can be wonderful family dogs for active households that can offer plenty of exercise, training and company, ideally with outdoor space and access to water. Affectionate and people-focused, they are often good with children when raised well. They are not suited to people who are out for long hours or who want a low-energy, low-maintenance dog.
What health problems do Portuguese Water Dogs have?
Generally a hardy breed with a typical lifespan of around 11–13 years, but like all pedigrees it has some inherited conditions. UK buyers should choose breeders who follow Kennel Club and breed-club health screening, including eye testing, hip scoring and relevant DNA tests. Good ear care after swimming and a healthy weight support long-term health; always ask your vet.
Are Portuguese Water Dogs good with children?
Good with children. As a general guide, Portuguese Water Dogs tend to be patient and tolerant. Whatever the breed, always supervise dogs and young children and teach kids to interact gently.
How much exercise does a Portuguese Water Dog need?
As a healthy adult, a typical Portuguese Water Dog needs 90 minutes to 2 hours of exercise a day (90–120 minutes), split across walks plus play. Higher-energy dogs also need mental stimulation — sniffing, training games and puzzle feeders — to stay settled. Puppies, seniors and dogs with health conditions need less — ask your vet.
Do Portuguese Water Dogs shed a lot?
Minimal shedding. Coat upkeep is high upkeep — plan on frequent brushing and regular trips to a groomer.
Are Portuguese Water Dogs easy to train and good for first-time owners?
Manageable for committed beginners. Portuguese Water Dogs are best for owners ready to commit to consistent training and plenty of activity. Reward-based training and early socialisation help any dog.
Do Portuguese Water Dogs bark a lot?
Quiet. They are usually fairly easy-going about barking, though any dog will bark if bored or under-exercised.
Are Portuguese Water Dogs good with other dogs?
Sociable with other dogs. Early, positive socialisation with other dogs from a young age makes a big difference.
Do Portuguese Water Dogs suit flats or smaller homes?
Best with a garden. A Portuguese Water Dog is happiest with access to a secure garden and regular outdoor exercise.
