History and origin
The FCI standard says that in the past the Portuguese Water Dog could be found all along the Portuguese coast. Then, because fishing methods changed, it remained mainly in the Algarve, now considered its place of origin. Wikipedia says fishermen taught it to herd fish into nets and to retrieve whatever was lost in the water.
Wikipedia says that in the 1930s the breed was on the verge of disappearing when the shipowner Vasco Bensaude sought out the fishermen's dogs to rebuild it. His best-known dog was Leão (1931–1942).
How the breed developed
- Ancient times – The fishermen's dog all along the Portuguese coast.
- 1930s – Vasco Bensaude begins rebuilding the breed.

Physical characteristics
The standard describes it as a harmonious, balanced, powerful and well-muscled dog, almost square, with very well-developed muscles from constant swimming.
General appearance
The abundant coat covers the whole body, without undercoat, in two varieties: long and wavy, slightly glossy, or shorter and curly, dense and dull, with cylindrical curls. It forms a topknot on the head. The AKC says it can be given a “lion clip” or a “retriever clip”.

Training and socialisation
The standard describes it as exceptionally intelligent, understanding and obeying any command easily and willingly. It is impetuous, wilful, brave, sober and resistant to fatigue, with a serious, attentive expression and remarkable sight and sense of smell.
The AKC says it responds well to obedience training, but often thinks for itself and sometimes tests its owner's will. It needs positive methods and daily physical and mental activity.
Tips for effective training
- Use positive methods. The AKC recommends them.
- Keep its mind busy. It has a great need for mental stimulation.
- Let it swim. It is an excellent swimmer and diver.
- Do not leave it alone for long. It demands attention and contact with people.
Activity needs and lifestyle
The AKC says it is an athletic, active breed that needs serious exercise every day: long walks and play sessions. It does well at obedience, tracking, agility, rally and dock diving.
| Activity | How often | Why it matters |
|---|---|---|
| Long walks | daily | Very high energy |
| Swimming | as often as possible | A water dog |
| Dog sports | weekly | Mental activity |
Tips for a balanced life
- It suits active families.
- Set aside time or budget for clipping.
- Dry its ears after swimming.
Care and health
Coat and skin care
The AKC says the dense, abundant coat is considered hypoallergenic, but it needs regular, extensive grooming. It can be given a “lion clip” (hindquarters and muzzle shaved) or a “retriever clip” (the whole body at about 2.5 cm).
Common health problems
The AKC says it is generally healthy, and responsible breeders test their dogs for:
| Condition | Description | Common symptoms |
|---|---|---|
| Hip dysplasia | The hip joint forms incorrectly and, over time, arthritis develops | Limping, difficulty getting up or jumping, hip pain |
| Progressive retinal atrophy | The retina gradually degenerates | Has trouble seeing at night, then sees less and less well |
| GM1 gangliosidosis | An inherited neurological disease, detected by a DNA test | Unsteady gait, trembling |
| Juvenile dilated cardiomyopathy | A serious heart disease in puppies | Sudden weakness, laboured breathing |
Other care
- Check the ears regularly, especially after swimming.
- Brush its teeth often.
- Ask for the parents' DNA tests.
Diet and nutrition
The AKC says some dogs gain weight easily, so calories and weight should be watched.
Tips for a healthy diet
The table gives a starting estimate, calculated with the formula from the Merck Veterinary Manual. The first two calorie columns show the calories per day for a healthy adult dog. The last column shows what this means in dry food with 3,500–4,000 kcal per kilogram.
| Dog's weight | Calories per day (neutered) | Calories per day (not neutered) | Dry food per day (approximate) |
|---|---|---|---|
| 16 kg | 900 kcal | 1,010 kcal | 220–290 g |
| 20 kg | 1,060 kcal | 1,190 kcal | 260–340 g |
| 25 kg | 1,250 kcal | 1,410 kcal | 310–400 g |
- Split the food into two meals a day.
- Treats count towards the daily portion.
- A dog is at the right weight when you can feel its ribs under the coat without pressing hard.
Foods to avoid
Some human foods are dangerous for dogs: chocolate, coffee, grapes and raisins, onions, garlic, xylitol (a sweetener used in chewing gum), macadamia nuts and alcohol.
Reproduction and development
Physical and emotional maturity
In dogs, sexual maturity usually comes between 6 and 12 months. Most breeds become adults at around 13–15 months.
Mating and pregnancy
Pregnancy lasts about 63 days, counted from ovulation. Mating a female on her first heat is not recommended. The FCI standard requires that only healthy dogs of typical breed appearance are used for breeding.
Caring for the puppies
In dogs, a litter has 5–6 puppies on average, and the number rises with the size of the breed. Socialisation starts in the first weeks: gentle handling, everyday noises and new people.
