Coat and looks how to spot one

curly, low-shedding double coat

A strong, upstanding water dog covered in tight, crisp ringlets with a natural oil that helps shed water. The face is smooth, a topknot of long loose curls falls over the eyes, and the tail is curly only at the base before tapering into a smooth 'rat tail'.132

Coloursrich liver to dark liver with a purplish sheen (puce liver)31

Personality what they are like

Alert, curious and full of energy, with a playful, comic streak that earns it the title of clown of the spaniel family. It is loyal and steady with its people and may be reserved with strangers until it gets to know them.312

Daily activity how busy a day looks

Very high. The Royal Kennel Club suggests more than two hours of exercise a day, and the breed loves swimming, retrieving and mentally challenging work.45

Grooming and care the hands-on bits

Brush and comb more than once a week to stop the curls from matting; the coat sheds very little.42

Home where they are happiest

Best suited to a country home with a large garden and regular chances to swim.4

Company who they like around

A devoted family companion that likes to be involved; early socialisation helps it feel relaxed with visitors.12

The story where it all began

Water dogs used for hunting wildfowl are mentioned in Ireland from around 1600. The modern breed was fixed in the 1830s by Justin McCarthy of Dublin, who is regarded as its father even though he left no breeding records. The Irish Water Spaniel Club was founded in 1890.12
