The Portuguese Water Dog, also known as the Algarvian Water Dog, or Portuguese Fishing Dog, is a breed of dog that originated from the Algarve region of Portugal. From there the breed expanded to all around Portugal's coast, where they were taught to herd fish into fishermen's nets, retrieve lost tackle or broken nets, and act as couriers from ship to ship, or ship to shore.

Questions people ask

Adult males usually weigh 19–25 kg and females 16–22 kg. Most are close to their full size by around 15 months, though the last little bit of filling out takes longer. Growth reference: Salt et al. 2017, WALTHAM (15–30 kg band).
No Portuguese Water Dog cycle figures are published here yet, so this is general guidance rather than a breed number: most females have a first season somewhere between six and fifteen months, and cycles then settle to roughly every 180 days. Smaller breeds tend to start earlier and larger ones later.
The median is 13 y. Median survival across 215 UK dogs (VetCompass, McMillan 2024) · half live 10–15 y. How the later years go comes down to weight, teeth, exercise and regular check-ups far more than to the breed.
