Irish Water Spaniel

The Irish Water Spaniel (IWS) is the tallest of all spaniels. His appearance is distinctive: dense liver-colored curls cover the body, a smooth tapered “rat tail” serves as a rudder in water, and a topknot of loose curls frames the face.

Beneath the distinctive appearance is a serious working dog. He was bred to be a rugged, all-weather retriever capable of braving the cold waters of the Irish coast. He is intelligent, energetic, and devoted to his family, while remaining reserved with strangers.

History and Origin: The Shannon Spaniel

The Irish Water Spaniel is a native of Ireland, specifically the marshes and bogs around the River Shannon. His origins are ancient and murky, lost in Irish folklore. He likely descends from the Poodle, the Portuguese Water Dog, and the Barbet (French Water Dog), mixed with indigenous Irish spaniels.

The McCarthy Influence

The modern breed was essentially created by one man: Justin McCarthy of Dublin. In the mid-19th century, McCarthy refined the breed type, focusing on the distinctive curly coat and the “rat tail.” His dog, Boatswain, born in 1834, is considered the father of the modern breed. Boatswain lived to be 20 years old and sired a dynasty. By the late 1800s, the IWS was the third most popular sporting dog in England. While his popularity has waned in favor of the easier-to-groom Labrador, he remains a cherished breed for those who appreciate his unique character.

Physical Characteristics: A Dog of Distinction

The Irish Water Spaniel is a sturdy, upstanding dog with a “barrel” chest (ribs well sprung) to hold massive lungs for swimming.

• Height: Males 22–24 inches (56-61 cm); Females 21–23 inches (53-58 cm).
• Weight: 55–68 pounds (25-31 kg).

Distinctive Features

• The Coat: The body is covered in dense, tight, crisp ringlets. The coat is oily to the touch (to repel water) and provides insulation against ice. The color is always solid liver (a rich reddish-brown with a purple hue).
• The “Rat Tail”: This is the breed’s most controversial feature. The tail is thick at the root and covered in curls for a few inches, then suddenly becomes smooth and tapers to a fine point. It looks like a rat’s tail, which aids in swimming (acting as a rudder without drag).
• The Topknot: A mass of long, loose curls on top of the head that hangs down over the eyes in a “widow’s peak,” giving him a rakish look.
• The Face: Unlike the Poodle, the face is naturally smooth (short hair), meaning he doesn’t need his face shaved.

Temperament and Personality

The IWS is lively, mischievous, and inventive.

The Entertainer

He is playful and known to engage in attention-seeking behaviors—hiding objects or bringing unsolicited items to his owners. He tends to remain energetic and playful well into old age.

The Worker

He has a high drive. He loves to swim and retrieve. If you throw a ball into a lake, he will not stop until he gets it—even if he has to dive underwater (which he does often). He is tireless in the field and needs a job to do.

The Watchdog

He is naturally alert and makes an excellent watchdog. His bark is deep and authoritative. Unlike the “everyone is my best friend” Golden Retriever, the IWS can be reserved with strangers. He takes a “wait and see” approach until properly introduced.

Training and Exercise Needs

Exercise: Vital for Sanity

A bored Irish Water Spaniel is a destructive Irish Water Spaniel.

• Daily Needs: He needs vigorous exercise. A 20-minute walk is not enough. He needs to run, swim, or retrieve for at least an hour a day.
• Swimming: He is a natural swimmer with webbed feet. Swimming is the best exercise for him.

Training: The Intelligent Rebel

He is intelligent but can be willfully independent.

• Motivation: He learns quickly but bores easily. If you repeat a drill too many times, he will start improvising (which usually means doing it wrong on purpose). Keep training sessions short, varied, and fun.
• Socialization: Because of his natural reserve, early socialization is crucial to prevent shyness or sharpness.

Health and Lifespan

The Irish Water Spaniel typically lives 12 to 13 years.

• Hip and Elbow Dysplasia: Common in the breed.
• Hypothyroidism: Can cause weight gain, lethargy, and poor coat quality.
• Drug Sensitivity: Like many herding/working breeds, some IWS carry the MDR1 gene mutation, making them sensitive to certain drugs (like Ivermectin). They should be tested.
• Ear Infections: The heavy, hairy ears trap moisture and wax. Weekly cleaning is mandatory.

Grooming and Care

The Curly Coat

The coat is hypoallergenic (low shedding) but high maintenance.

• Brushing: He must be brushed 2-3 times a week to prevent mats. You must brush down to the skin (“line brushing”).
• Trimming: He needs a “scissor trim” every 6-8 weeks to keep the curls neat and prevent him from looking like a swamp monster.
• The “Clean Face”: The smooth hair on the face and tail needs little care, which is a blessing compared to a Poodle.

Is an Irish Water Spaniel Right for You?

The Irish Water Spaniel suits an active owner with specific breed knowledge.

Yes, if:

• You want a dog that stands out. You will be stopped on the street.
• You suffer from allergies. He is low shedding (but not non-shedding).
• You are an active person. You love hiking and swimming.
• You have a sense of humor. You want a dog that makes you laugh.

No, if:

• You are put off by the “rat tail.” It’s a dealbreaker for some.
• You want a low-maintenance dog. He needs grooming and exercise.
• You want a dog that loves every stranger instantly. He is discerning.
• You live in a small apartment. He is a big, bouncy dog.

For the active family who wants a working retriever with a lively temperament and a distinctive appearance, the Irish Water Spaniel is a capable and engaging choice. He excels at water work and thrives with owners who can provide both vigorous exercise and consistent training.
