Portuguese Water Dog: Portugal’s Web-Footed Fishing Companion
Portuguese Water Dog is a medium-sized working breed from the Algarve coast, kept for centuries to drive fish into nets and carry messages between boats.
The FCI sets males at 50 to 57 cm and 19 to 25 kg, females at 43 to 52 cm and 16 to 22 kg, and describes a dog that is almost square in proportion with webbing across the whole length of its toes.
The Portuguese Water Dog’s reputation rests on three things that are easy to check and often misreported: a coat with no undercoat, a specific set of seven health screens, and a working history that explains both the intelligence and the wilfulness. This guide separates what the standards say from what marketing says.
What Is a Portuguese Water Dog?
The Portuguese Water Dog is a muscular, water-adapted retriever-type dog with a profuse coat, a heart-shaped ear held against the head and a tail that curls into a ring when the dog is attentive.
The FCI classifies it in Group 8 as a water dog, working without a trial, and lists its use as assistance with fishing and retrieving alongside companionship.
These are the headline figures, with the source noted because the registries publish different numbers.
| Portuguese name | Cão de Água Português |
| FCI standard | No. 37, Group 8, Section 3, water dogs |
| Origin | Portugal, with the Algarve as the breed’s birthplace |
| FCI acceptance | 1955; current standard published 2008 |
| AKC recognition | 1983, with eligibility from January 1984 |
| Height | Males 50 to 57 cm, females 43 to 52 cm |
| Weight | Males 19 to 25 kg, females 16 to 22 kg |
| Coat | No undercoat; long and wavy, or shorter and curly |
| Colours | Black, brown of various shades, or solid white, with limited white markings |
| Lifespan | 11 to 13 years in the US, 10 to 14 in UK sources |
| Best for | Owners who want a trainable working dog and will groom daily |
How Big Do Portuguese Water Dogs Get?
The FCI standard is unusual in publishing an ideal height alongside the range, which makes it more useful than most breed profiles. The American figures run slightly wider at the top of each band.
| Source | Male and female sizes |
|---|---|
| FCI standard | Males 50 to 57 cm, ideal 54; females 43 to 52 cm, ideal 46 |
| FCI weights | Males 19 to 25 kg; females 16 to 22 kg |
| AKC | Males 20 to 23 inches, 42 to 60 lb; females 17 to 21 inches, 35 to 50 lb |
| Hill’s | Two different sets on one page, 15 to 25 kg in the text and 19 to 27 kg for males in the panel |
Two things follow from the comparison. The AKC male ceiling of 23 inches converts to 58.4 cm, which sits above the FCI maximum of 57 cm, and the AKC male weight ceiling of 60 lb converts to 27.2 kg against an FCI maximum of 25 kg. A large but correct American dog can be oversize on the European standard, and oversize is a disqualifying fault there.
The UK Kennel Club publishes no height or weight for the breed, only a “medium” size band.
What Makes the Portuguese Water Dog a Water Dog?
The adaptations are structural, and the standard describes them precisely. This is the list to quote when someone asks what a water dog actually is:
- The webbing extends across the whole length of the toes, is made of limp tissue, and is covered with abundant long hair.
- The feet are rounded and flat with slightly arched toes and a hard central pad, and the nails should not reach the ground.
- The tail is thick at the base, curls into a ring when the dog is alert, and the standard calls it a useful aid for swimming and diving.
- The coat has no undercoat, which is what makes it water-resistant rather than waterlogged.
- Dewclaws are a disqualifying fault, so a show-line puppy should never have them.
- A docked or rudimentary tail is also disqualifying, and the tail is a working part rather than an ornament.
The Portuguese Water Dog’s behaviour matches the anatomy. The standard describes a dog that will jump into the sea to retrieve escaped fish, dive when necessary, and work as a liaison between boats and shore over long distances.
What Colours Can a Portuguese Water Dog Be?
There are two coat varieties and a narrower colour palette than most photos suggest. The permitted combinations are:
- Black, brown in various shades, or solid white.
- Black or brown with white markings, permitted only on the muzzle, topknot, neck, forechest, belly, tail tip and lower limbs below the elbows and hocks.
- Two coat varieties: long and wavy with a slight sheen, or shorter and curly with compact cylindrical curls.
- No albinism. A white dog must still have a pigmented nose, eyelids and mouth, and the nose may never be marbled.
The UK Kennel Club takes a slightly different view of what owners will see in the ring, listing apricot, cream and gold as non-breed-standard colours. Those Portuguese Water Dogs exist. They are not correct under the FCI standard, which is a distinction worth making calmly rather than dramatically.
What Are the Lion Clip and the Retriever Clip?
Partial clipping is not a fashion choice in this breed. The FCI standard describes it as typical, with the hindquarters, muzzle and part of the tail clipped and a plume of full-length hair left at the tail tip. Two named clips come from that tradition:
- Lion clip: the hindquarters and muzzle are clipped close to the skin, leaving a mane over the forequarters. The Kennel Club notes that the lion trim is said to aid propulsion through water.
- Retriever clip: the whole coat is clipped to about an inch and follows the outline of the dog, with the tail tip left long.
The AKC page manages to define the retriever clip twice in incompatible ways, once as a one-inch clip and once as “all hair left intact”. Trust the one-inch version, which matches Hill’s and matches what groomers actually do.
A third option circulates among pet owners as the puppy clip, a simple all-over trim. No registry names it.

Where Does the Portuguese Water Dog Come From?
Portugal, and the FCI is specific about where. The breed was once found along the entire Portuguese coast, and as fishing methods changed it survived mainly in the Algarve, which the standard now calls its original birthplace.
The FCI treats it as an autochthonous Portuguese breed, meaning it developed in place rather than being imported and refined elsewhere.
Claims about the breed’s antiquity are where the sources get loose. One UK pet site places its origin on the central Asiatic steppes around 700 BC, and neither the FCI nor the AKC makes that claim. This guide sticks to what is documented: the Algarve, the fishing fleet, and the twentieth-century recovery.
The Portuguese Water Dog’s working job description is well recorded, and it explains the modern dog better than any origin story. In the fishing ports the breed did all of this:
- Driving shoals of fish into the nets, which is why the Kennel Club calls it a herder of fish.
- Retrieving nets and tackle that broke or went overboard, diving when required.
- Carrying messages between boats at sea and between ship and shore.
- Acting as a foghorn, with a resonant bark used to warn other boats of a vessel’s position in thick fog.
The twentieth century nearly ended the breed. As fishing industrialised, numbers collapsed, and the Kennel Club dates the steepest fall to the 1950s and 1960s. Credit for the recovery goes to Vasco Bensaude, a Portuguese shipping magnate who began breeding the remaining dogs in the 1930s. Both the AKC and Hill’s misspell his name as Bensuade.
The American line is better dated than most. The Portuguese Water Dog Club of America was founded in 1972, and the AKC admitted the breed in 1983 with eligibility from January 1984, though its own page states both 1983 and January 1984 as the recognition date. Worldwide visibility arrived in 2009 when the Obama family brought Bo to the White House, followed by Sunny in 2013.
What Is the Portuguese Water Dog’s Temperament Like?
The FCI’s description is unusually warm for a standard. It calls the breed exceptionally intelligent, able to understand and obey easily and happily any order from its owner, then adds the counterweight: impetuous, wilful, courageous, tireless, with a severe and attentive expression.
The AKC puts the same dog in American terms. It calls the breed super-smart and very biddable, then warns that a Portie often thinks independently and may challenge its owner’s will. Biddable and compliant are not the same claim, and the gap between them is where most training problems live.
Four traits shape daily life with a Portuguese Water Dog:
- Attachment: the breed is demanding of attention and human contact, and Hill’s rates its social needs at the top of the scale.
- Vigilance: it is mistrustful of strangers and barks at arrivals, which makes it a good watchdog and a poor guard dog given its size.
- Exuberance: the AKC warns that Porties can be too much for families with very young children, which is a comment on enthusiasm rather than aggression.
- Tolerance of other animals: Hill’s reports that dogs and cats are fine if raised together, while rodents, birds and reptiles should be kept out of reach.
The 1985 breed health survey put temperament second on its list of pressing problems, behind hip dysplasia. By the 2005 survey, almost half of respondents reported a temperament or behaviour issue.
That is a breed-wide signal, and it argues for a breeder who talks openly about temperament rather than one who describes every litter as calm.
How Much Exercise Does a Portuguese Water Dog Need?
For a Portuguese Water Dog, the sources converge on roughly an hour, with a big caveat. The Kennel Club allows up to an hour a day, Hill’s asks for more than 40 minutes, and the AKC simply says the breed requires vigorous exercise every day. None of them is describing a dog that will be satisfied by a lead walk.
A week that works for a Portuguese Water Dog looks like this:
- Four days with a 45 to 60 minute walk plus a training session, because the brain needs a shift as much as the legs do.
- One day of swimming or dock diving, which is the breed’s natural outlet and the reason the webbed feet exist.
- One day of scent games, fetch or puzzle work when the weather rules out anything else.
- One rest day with gentle walking, since a working dog that never rests accumulates small injuries.
The sports that suit the breed are the ones that reward cooperation: obedience, tracking, agility, rally and dock diving. If the weather kills the outdoor plan, these ways to tire out a high-energy dog cover the indoor options.
How Do You Groom a Portuguese Water Dog?
This is the largest time commitment the Portuguese Water Dog asks for, and the sources are unanimous about it. The AKC calls for regular and extensive grooming, the Kennel Club says every day, and Hill’s rates grooming at the top of its scale and calls the breed high maintenance.
| Task | How often |
|---|---|
| Brushing and combing to the skin | Daily, in sections, or mats form behind the ears |
| Clipping | Every four to eight weeks depending on the clip you choose |
| Bathing | Occasionally, when the coat stops rinsing clean |
| Ear check and clean | Weekly, which the AKC singles out |
| Nail trimming | Every few weeks, and never let them reach the ground |
| Dental care | Daily brushing where the dog allows it |
The tools that do the job are a slicker brush, a metal comb, a dematting rake and clippers with a guard. A pin brush alone will skim the surface and leave the undergrowth to mat at the skin.
Is the Portuguese Water Dog Hypoallergenic?
No dog is truly hypoallergenic, and the Portuguese Water Dog is a good example of why the label needs care. What is true, and useful:
- The coat has no undercoat under the FCI standard, and the breed is described as low-shedding.
- Hill’s points out that the hypoallergenic claim may or may not hold for a particular person, which is the honest version.
- Dogs with an improper coat can carry some undercoat and shed, so a puppy’s coat matters if allergies are the reason you chose the breed.
The AKC page calls the coat non-allergenic as an absolute. That is a marketing sentence rather than a clinical one. If allergies are driving the decision, our guide to hypoallergenic dogs explains what the term can and cannot mean.
What Health Problems Do Portuguese Water Dogs Have?
The Portuguese Water Dog has one of the better-documented health programmes in the dog world, and it is worth stating precisely because the diseases are serious and the testing is specific.
The parent club and the AKC agree on seven recommended screens:
- Hip evaluation, by radiograph at two years of age or older.
- An eye examination by a board-certified ophthalmologist, under the CAER scheme.
- A DNA test for GM1 gangliosidosis, a storage disease.
- A DNA test for microphthalmia syndrome.
- A DNA test for juvenile dilated cardiomyopathy, known as JDCM.
- A DNA test for early onset progressive retinal atrophy, or EOPRA.
- A DNA test for prcd progressive retinal atrophy.
Two of those conditions deserve a sentence each, because the research is concrete. A 2002 study in the Journal of Veterinary Internal Medicine examined 124 puppies by echocardiography and found 10 affected by JDCM, with inheritance consistent with an autosomal recessive pattern, and it noted that only echocardiography detected affected puppies one to four weeks before acute heart failure appeared.

A 1988 case report in Veterinary Pathology described GM1 gangliosidosis in three siblings aged five to seven months, with brain ganglioside markedly elevated and enzyme activity under ten percent of normal.
The breed’s history with PRA is a useful case study in why testing changes. prcd-PRA was first reported in the breed in 1990, the mutation was identified in 2005, and a second form, EOPRA, was reported in the autumn of 2012. Each discovery added a test and changed what a responsible breeding pair looked like.
Other conditions named by the parent club include Addison’s disease, for which the breed is predisposed with a median age at diagnosis of four to six years, plus follicular dysplasia, allergies, distichiasis, cataracts, epilepsy, hypothyroidism and cancers. Hip dysplasia remains the primary orthopaedic concern.
Hill’s publishes no health section for this breed at all, and the Kennel Club lists five items against the parent club’s seven. Ask for all seven, in writing, for both parents, including the DNA results rather than a clearance statement.
Any dog that collapses, struggles to breathe, bleeds heavily or shows sudden severe pain needs a vet immediately. This guide is educational and does not replace veterinary advice for the dog in front of you.
Is the Portuguese Water Dog the Right Dog for You?
The Portuguese Water Dog suits an owner who wants a partner rather than a pet, has water or a sport to share, and will accept a daily grooming routine as part of the deal. Get those three right and the dog is funny, capable and deeply attached.
It fits households that can say yes to all of this:
- Someone is home for most of the day, or day care is part of the plan.
- You will brush and comb daily, and pay a groomer for clipping every four to eight weeks.
- You can offer swimming, dock diving or a structured dog sport.
- You want a dog that participates in family life and will not thrive in a kennel or a yard alone.
Choose another breed if any of these describes your situation:
- You want a low-maintenance coat, because this breed has none.
- You need a dog that tolerates long hours alone without complaint.
- You are choosing the breed purely on the hypoallergenic label.
- You are not prepared to ask breeders for seven separate test results.
If the water-dog temperament appeals but the grooming does not, our Portuguese Podengo guide covers the other Portuguese hunting breed, with a coat you can brush in five minutes. If attachment is the part that attracts you, read about separation anxiety in highly attached dogs before you commit.
Compare it against the alternatives in our Dog Breeds hub, and ask any breeder for the seven screens before you discuss a deposit.
