A nearly smooth, tapering tail completes a tightly curled body. This whip tail or rat tail is found in no similar breed, according to the FCI standard. Precisely for that reason, its writers consider distinct Irish ancestors likely for the Irish Water Spaniel.

Water dogs before shotguns
The standard says exact origins are unclear. A widespread view traces water spaniels to dogs reaching Ireland from Persia via Spain. The first Irish reference to water dogs pursuing waterfowl dates from 1600, so water-resistant-coated dogs worked there before shotguns arrived. The Irish Water Spaniel Club formed in 1890.
Humour for family, reserve for strangers
Proud, highly intelligent and enduring, with bold, eager enthusiasm and enormous stamina: the standard’s portrait. It adds an unusual line: a good family dog with a sense of humour, but suspicious of strangers. Expect silliness at home and a careful initial assessment of visitors. Early, friendly encounters with many people help.
Built for reeds, scrub and cold water
Suitable under the standard for most hunting, searching, often pointing and readily retrieving from thick cover, the dog was favoured by wildfowl hunters. A slight rolling movement from the barrel chest is typical. Swimming and water retrieving are natural tasks. Other curly water workers include the Curly Coated Retriever and the American Water Spaniel.
What studies show
The British longevity study gave a median 10,8 years, below crossbreeds at 12,0. Mortality risk was a third higher, but only 174 dogs underpin the analysis (McMillan et al. 2024). Hair loss is another concern. A British investigation found 20 dogs with bald areas without itching or inflammation, always in the same body regions. Changing diet improved skin and coat in most (Cerundolo et al. 2000). Pedigree analysis found familial clustering (Cerundolo et al. 1999). Ask specifically about hair loss in the line.
Keeping curls in order
Oily ringlets protect in water but mat without care. Comb regularly, remove plant debris and let the coat dry after swimming.
A good choice if
You enjoy water, long walks and a dog with wit and an independent mind. Dog experience or a good training school helps.
Less suitable if
Your home is constantly full of guests the dog must instantly love, or wet curls in the hallway bother you. Then this Irish water specialist belongs on someone else’s shore.
