Irish Water Spaniel scorecard
Overview
The Irish Water Spaniel is the tallest of the spaniels and one of the most distinctive of all gundogs, with a dense coat of crisp liver-coloured curls, a topknot of loose curls on the head, and a smooth, tapering "rat tail" that is unique among breeds. Bred to retrieve from water and rough cover, it is an intelligent, eager and versatile working dog.
Standing around 51–59 cm and weighing roughly 20–30 kg, it is a strong, athletic dog with a low-shedding curly coat that needs regular care. Affectionate and devoted with its family, it combines a clownish sense of fun with serious working ability, suiting active owners who can keep it busy.
Good to know — a Irish Water Spaniel needs plenty of space and manageable for committed beginners. Every dog is an individual, so meet a few and chat to a good breeder or rescue before deciding.

History & origins
The breed as we know it was developed in Ireland in the 19th century, with Justin McCarthy of Dublin generally credited as a key figure in fixing the type around the 1830s. Its exact ancestry is uncertain, but it likely drew on older Irish water dogs and curly-coated retrieving breeds, producing a specialist for wildfowling in the bogs and waterways of Ireland.
It was among the breeds recognised in the early days of organised dog showing and is registered today by the UK Kennel Club within the Gundog group and by the FCI. Never numerous, it remains a relatively rare breed, valued by enthusiasts for its working talent and singular looks.
Temperament & family fit
Irish Water Spaniels are intelligent, affectionate and good-humoured dogs with a well-known playful, even mischievous, streak. They bond strongly with their families and are typically good with children, and many retain a youthful sense of fun throughout their lives.
They can be somewhat reserved or aloof with strangers compared with the more universally outgoing spaniels, which makes early and ongoing socialisation important. They generally get on with other dogs, are not especially noisy, and are alert without being natural guard dogs. As sensitive, clever animals they do best with owners who engage them thoughtfully.
- Families with children of all ages
- Owners ready for consistent training
- Active homes with plenty of space
Training & intelligence
Highly intelligent and keen to work, the breed learns quickly and enjoys having a task, but its cleverness comes with a degree of independence and a need for variety to prevent boredom. Positive, motivating, reward-based training brings out the best in this sensitive dog, while repetitive drilling or harsh corrections can cause it to switch off.
Early socialisation helps temper any reserve with strangers, and recall and retrieve work play to the breed's natural strengths. With its stamina and brains, the Irish Water Spaniel excels at gundog work, water retrieving and a range of canine sports.
- Start socialisation & handling early
- Reward-based methods only — no harsh corrections
- Channel energy into training games & enrichment
Exercise needs
A healthy adult Irish Water Spaniel typically needs 90 minutes to 2 hours a day (roughly 90–120 minutes), split across walks, play and a little training. Higher-energy dogs also need their brains tired — sniffy walks, training games and puzzle feeding go a long way. Puppies, seniors and dogs with health conditions need adjusted amounts — check with your vet.
Grooming & coat
The curly, low-shedding coat needs regular care to prevent matting, with brushing and combing several times a week and periodic trimming to keep it tidy. Because it sheds very little, loose hair stays in the coat and must be removed by grooming. Pay particular attention to the hairy, pendulous ears, which need regular checking and cleaning to prevent infection, and trim hair around the pads.
- Brush several times a week
- Bathe every few weeks or as needed
- Check ears, nails and teeth weekly
Feeding considerations
Feed a complete, quality diet appropriate to the dog's age and active lifestyle, split into two meals a day to suit a large, deep-chested frame. As with other deep-chested breeds, avoid one large daily meal and keep vigorous exercise away from mealtimes. Match portions to body condition to keep this athletic dog lean and fit.
Irish Water Spaniel health & costs
Before bringing a Irish Water Spaniel home it pays to budget for the whole picture — food, insurance, grooming and routine vet care all add up. The figures below are typical UK estimates for a healthy adult; your real costs vary with where you live, your dog's health and the cover you choose.
Food
£600–850 / year
Complete food sized to weight & life stage
Insurance
£35–62 / month
Lifetime cover — varies by age, breed & area
Grooming
£400–700 / year
Regular professional grooming
Routine vet care
£200–450 / year
Vaccines, flea/worm, annual check
The Irish Water Spaniel is generally a healthy and resilient breed, though its small population means responsible breeders are mindful of genetic diversity and screen for the conditions known to occur. Some individuals can be sensitive to certain drugs, so owners should mention the breed to their vet.
Prospective owners should seek puppies from health-tested parents, including hip scoring and eye testing in line with UK Kennel Club guidance. Good ear care, weight management and routine veterinary checks support a typical lifespan of around 10–12 years.
Common health conditions to be aware of
- Hip dysplasia — a developmental joint condition; breeding stock should be hip-scored.
- Ear infections — long, hairy, pendulous ears trap moisture and need regular cleaning and checking.
- Hypothyroidism — an underactive thyroid affecting coat, weight and energy, manageable with treatment.
- Entropion and other eye conditions — inward-rolling eyelids and assorted eye problems; eye testing of breeding dogs is advised.
- Drug sensitivity — some individuals react adversely to certain anaesthetics or medications; inform your vet of the breed.
- Gastric dilatation-volvulus (bloat) — a life-threatening emergency to which deep-chested breeds are prone.
These reflect typical, size- and coat-related risks for dogs like the Irish Water Spaniel; individual breeds carry their own predispositions. Always buy from health-tested parents and speak to your vet — this isn't a diagnosis.

Bringing home a Irish Water Spaniel puppy
Puppies need controlled exercise (a rough guide is five minutes per month of age, twice a day) to protect growing joints, little-and-often meals of a complete puppy food, early socialisation, and a calm routine for toilet training and sleep. Book first vaccinations, microchipping and a vet check early.
New puppy checklist →Caring for a senior Irish Water Spaniel
As they age, watch weight, joints and teeth, switch to a senior diet if your vet advises, keep exercise gentle but regular, and consider orthopaedic bedding and ramps. Twice-yearly vet checks help catch issues early — larger breeds age sooner, so start senior care from around 6–7 years.

Are Irish Water Spaniels hypoallergenic?
No dog is truly hypoallergenic, but the Irish Water Spaniel's dense, curly coat sheds very little, which some allergy sufferers tolerate better.

How much grooming does an Irish Water Spaniel need?
Quite a lot. The curly, low-shedding coat needs brushing and combing several times a week to prevent matting, plus periodic trimming to keep it tidy. Because it sheds so little, loose hair must be removed by grooming. Pay particular attention to the hairy, pendulous ears, which need regular checking and cleaning to prevent infection.
How much exercise does an Irish Water Spaniel need?
This energetic working gundog needs well over an hour a day of varied activity plus mental stimulation, ideally including the swimming it was bred for. Access to safe water is a real bonus and they thrive with space to run. Without enough physical and mental outlet they can become bored and restless, so an active home is essential.
Are Irish Water Spaniels easy to train?
They are highly intelligent and keen to work, learning quickly and enjoying a task, but their cleverness comes with independence and a need for variety. Positive, motivating, reward-based training brings out their best, while repetitive drilling or harsh corrections can cause this sensitive dog to switch off.

Seek puppies from health-tested parents, including hip scoring and eye testing per UK Kennel Club guidance; typical lifespan is around 10–12 years.
Are Irish Water Spaniels good family dogs?
Yes, in active households that can provide exercise, mental challenge and ideally access to water.

How much exercise does an Irish Water Spaniel need?
As a healthy adult, a typical Irish Water Spaniel needs 90 minutes to 2 hours of exercise a day (90–120 minutes), split across walks plus play. Higher-energy dogs also need mental stimulation — sniffing, training games and puzzle feeders — to stay settled. Puppies, seniors and dogs with health conditions need less — ask your vet.

Minimal shedding. Coat upkeep is high upkeep — plan on frequent brushing and regular trips to a groomer.
Are Irish Water Spaniels easy to train and good for first-time owners?
Manageable for committed beginners. Irish Water Spaniels are best for owners ready to commit to consistent training and plenty of activity. Reward-based training and early socialisation help any dog.

Are Irish Water Spaniels good with other dogs?
Sociable with other dogs. Early, positive socialisation with other dogs from a young age makes a big difference.
Do Irish Water Spaniels suit flats or smaller homes?
