AKC: Irish Water Spaniel breed overview

Sporting group · Ireland

Irish Water Spaniel

Also called IWS, Whiptail, Shannon Spaniel

The tallest spaniel, dressed in waterproof liver curls and topped with a loose, clownish topknot.

The Irish Water Spaniel is a rare, athletic retriever bred for cold marshes and rivers. Its curly liver coat, topknot and nearly bare tail make it unmistakable, and its playful, sometimes goofy nature makes it good company for active owners. The coat is the ongoing commitment: it needs regular combing, trimming and drying to stay healthy.

Life with a Irish Water Spaniel

Irish wildfowlers needed a dog that could swim through cold, choppy estuaries, retrieve heavy ducks and geese, and keep working all day without chilling. The Irish Water Spaniel filled that role, and its tight, oily curls act almost like a wetsuit. Justin McCarthy's dog Boatswain, who reportedly lived to 18, is usually cited as the foundation of the modern breed, although McCarthy never revealed exactly how he produced his line.

At home the IWS is lively, funny and often mischievous. Owners describe a clown with a working brain: sneaking off with socks, launching into every puddle, and inventing games that involve carrying things from one room to another. It bonds strongly with its family and can be reserved or even aloof with strangers until properly introduced.

This is not a dog for a sedentary household. An IWS with too little to do becomes noisy, destructive or overexcited. With daily exercise, training and a job, even a playful one such as retrieving a canvas dummy from a lake, it is an engaging, loyal partner that loves water above almost everything.

What stands out

Grooming

This coat rewards a routine. Once or twice a week, work through it with a comb and a slicker brush down to the skin, focusing on the ears, armpits, collar area and between the hind legs. After swimming in salt water or muddy ponds, rinse with fresh water, squeeze out the excess and let the coat dry naturally so the ringlets reform.

Care guides for the Irish Water Spaniel

Feeding25 cups, in two meals. Working dogs in cold weather may need 20 percent more, while dogs with lighter routines need less.Read more Puppy growthIWS puppies grow quickly and reach adult height around 12 months, but they keep filling out until about 18 to 24 months. Mentally, they are slow to mature and often remain puppyish, energetic and mouthy until 2 years or later, which surprises owners of a dog that already looks grown.Read more ExerciseNinety minutes a day is a sensible floor for an adult, including off-lead running where safe, swimming, retrieving and training. The breed shines at field trials, dock diving, agility and obedience, and many will retrieve from water until you run out of patience before they run out of energy.Read more TrainingIWS are intelligent and keen to learn, but they have a stubborn streak and bore quickly with repetition. Short, varied sessions with food, toys and retrieves as rewards work best.Read more HealthIrish Water Spaniels are known to be affected by hip dysplasia, an underactive thyroid, some eye conditions and hair loss problems in certain lines. Breeders typically screen hips and elbows, test thyroid function and have eyes examined before breeding.Read more

Things owners are often surprised by

1It is the tallest of the spaniel breeds, with males reaching up to 61 cm (24 in).
2The tail is covered in curls only for the first 5 to 8 cm; the rest is short and smooth, earning the name 'whiptail'.
3The modern breed is linked to Justin McCarthy of Dublin and his dog Boatswain, whelped in 1834.
4Liver is the only accepted color, often with a purplish tint called puce.
5Its coat sheds very little, but loose hair tangles into the curls if left unbrushed.

Irish Water Spaniel questions

Do Irish Water Spaniels shed?

They shed very little, and loose hair tends to stay caught in the curls rather than landing on floors. That makes them appealing to some people with mild allergies, though no dog is fully allergen-free. Weekly combing is essential to remove that trapped hair before it knots into mats close to the skin.

Why does an Irish Water Spaniel have a rat tail?

The tail is thick and curly at the base, then tapers into a smooth, short-haired length that looks a little like a rat's tail. It is one of the breed's defining features in the show ring. Some suggest it helps with steering while swimming, although the exact reason it developed is not known.

Are Irish Water Spaniels good with children?

Most IWS are affectionate and playful with children they know, especially if raised together. Youngsters can be boisterous and mouthy, however, and a 25 kg dog in full bounce can knock over a small child. Supervision, teaching kids gentle handling, and training the dog to settle on a mat all make for a better family match.

Is the Irish Water Spaniel related to the Poodle?

The curly coat invites the comparison, and both breeds descend from old European water dogs, but the IWS is not a poodle cross. It developed separately in Ireland as a spaniel-type retriever. Its origins are partly uncertain because the breed's founder kept his breeding methods private.

How often should I bathe an Irish Water Spaniel?

Bathe only when the coat is genuinely dirty or smelly, perhaps every 6 to 8 weeks. Frequent bathing can strip the natural oils that make the coat water-resistant. Rinse with fresh water after swimming in salt or muddy water, and let the coat dry naturally so the curls reform.
