The heaviest and slowest of the English spaniels: calm, quiet and dignified at home, silent and methodical in the field. The Kennel Club places the Clumber on its list of Britain's vulnerable native breeds — 160 were registered in 2025. It needs moderate exercise, weight control and careful attention to eyes, ears and joints.

The Clumber Spaniel is the heaviest and slowest of the English spaniels: a long, low, white dog with a massive head and a strikingly quiet manner. He works in silence, at his own measured pace, and at home turns into a calm, dignified companion, deeply attached to his family. He is also one of the very few breeds whose rarity is not a figure of speech but an official designation with a number attached: the Kennel Club places the Clumber on its list of vulnerable native breeds.

The FCI standard describes the Clumber as “stoical, great-hearted, highly intelligent”, and adds a phrase that appears in no other spaniel description: a silent worker with an excellent nose. It was silence rather than speed that was historically valued in this breed. The same document warns openly that the Clumber has grown heavier over the decades, and that enthusiasts should take care that weight does not turn into weakness behind.
Interesting facts about the Clumber Spaniel
Rarity with an official definition. The Kennel Club maintains a list of the vulnerable native British and Irish breeds — those with fewer than 300 registrations a year — alongside a separate “at watch” list for breeds with between 300 and 450 registrations a year. The Clumber Spaniel sits on the first of those, the vulnerable list.
The figures themselves. According to the official registration statistics, 160 Clumbers were registered in Britain in 2025. Across the decade the figure has moved between 155 in 2024 and 285 in 2021 — the breed sits consistently well below the threshold of 300 and shows no sign of climbing out of the category.
Not the rarest in its own company. The same vulnerable list holds the Clumber’s relatives too: the Field Spaniel, with 48 registrations for 2025, is rarer again by a factor of three.
The silent hunter. The formula “a silent worker with an excellent nose” is not an owners’ advertising slogan but a phrase taken word for word from the FCI standard. The Clumber works quietly, and that quietness was historically valued when shooting in thick undergrowth.
The heaviest of the spaniels. A comparison of the standards bears this out: no other spaniel carries a top weight of 34 kg. Its nearest relatives are appreciably lighter — Sussex Spaniels, similar in build, remain a good deal more compact.
A breed as a scientific model. The description of PDP-1 deficiency in the Clumber mattered well beyond dog circles: the authors noted explicitly that a canine model makes it possible to study the consequences of disrupted regulation of the pyruvate dehydrogenase complex, which the human mutation known at the time did not allow.
History and origin: what is documented and what is merely retold
One point is beyond dispute: the name comes from Clumber Park in Nottinghamshire, the seat of the Dukes of Newcastle. Everything else belongs to the territory of retelling, and it is precisely here that breed pages tend to drift furthest from their sources.
The most widely repeated version runs like this: the French Duc de Noailles, saving his kennel from the French Revolution, sent his best dogs to England. Dozens of publications repeat it — recently even the introduction to a peer-reviewed genetics paper. The difficulty is that the earliest printed source says something rather different.
In William Barker Daniel’s Supplement to the Rural Sports (London, 1813), on p. 684, the spaniels are said to have been presented to an ancestor of the Duke while he was in France (when in France), by the Duc de Noailles. The direction of travel is therefore the opposite of the familiar story: no kennel was evacuated to England — an English aristocrat received dogs while abroad. There is no revolution and no date in that sentence at all. Later nineteenth-century writers cite Daniel directly: Vero Shaw (1881) does so openly, and Rawdon Lee (1893) dates the episode to “probably about the middle of the eighteenth century” — that is, before the Revolution — adding that he could find no trace of Clumbers in France itself.
The most sceptical account of the whole story comes not from an outside critic but from the British breed club. In its historical sketch the club calls the tale of flight from the Revolution a “wonderful (but fanciful) story”, and adds a claim anyone can check: “There is no mention in either of the Dukes’ papers to any gift or sale being made”. On the club’s reading, what is actually known is only that in the 1760s dogs were brought to Clumber Park from the Continent, with France not singled out.
The chronology supplies a further argument. The visual evidence quoted most often is Francis Wheatley’s painting The Return from Shooting, dated 1788 — that is, painted before the French Revolution began. The breed club points out that the three spaniels shown in it were described as “Springers or Cock-flushers” rather than as Clumbers, so the picture speaks for a long presence of heavy spaniels on these estates rather than for one breed.
The FCI standard itself words the origin with deliberate caution: Clumbers, it says, are said to have come in the first place from France over two hundred years ago, and were brought to Britain by the Duke of Newcastle, who bred them at Clumber Park. The registry, in other words, presents this as tradition rather than as an established fact — and that is the most honest formula on offer.
As for royal favour, the Clumber is linked with Prince Albert and Edward VII. The club and the registries repeat these statements consistently, yet each is given without a reference to an archival source. Caution is therefore in order: this is a durable tradition in how the breed is described, not a documented episode.
Breed standard: two registries, two different sets of figures
This is the most important passage on the page, because it is from here that the nonsensical “merged” ranges reach reference works. The FCI and the AKC describe the Clumber differently — not only in their figures, but in the very set of measurements they give.
FCI standard No. 109 (Group 8, Section 2 — spaniels; the valid edition dated 13 October 2010) sets weight only, and gives no height whatsoever. Ideal weight: dogs 29.5–34 kg, bitches 25–29.5 kg. The Kennel Club, whose breed standard underlies the FCI document, gives the same weights with an imperial equivalent and likewise quotes no height at all.
The American AKC does the opposite, setting both height and weight — and its upper weight limit is noticeably higher: dogs 70–85 pounds, bitches 55–70 pounds; ideal height 18–20 inches for dogs and 17–19 inches for bitches.

The metric conversions are ours; each registry publishes exactly the units shown in its own column.
The practical conclusion is straightforward. Ranges such as “25–39 kg” or “43–51 cm” belong to no standard at all: they arise when the lower figure is lifted from one registry’s line for bitches and the upper from another’s line for dogs. Dogs and bitches differ in both height and weight here, and folding the two into a single span is not sound.
The FCI standard also records a historical change in its own text: the breed grew heavier from roughly the 1950s onwards, and although the top weight for dogs stands at 34 kg, some individuals exceed even that figure. The gap between the British and the American numbers is therefore not a registry’s mistake but a reflection of real drift in type.
On colour the standard sets out a clear hierarchy that is very often flattened. A plain white body with lemon markings is preferred, while orange markings are permissible — lemon is the preferred variant, not an equal alternative. Slight head markings and a freckled muzzle are allowed. The Kennel Club lists lemon and white, orange and white, and their mirrored forms as the standard combinations.

In outline the Clumber is markedly more substantial and lower to the ground than the lighter Field Spaniel, and it is this pair, together with the Sussex Spaniel, that reference works confuse most often.
Character and temperament: a calm that should not be mistaken for idleness
The standard describes the Clumber’s temperament consistently: steady, reliable, kindly and dignified, “more aloof than other Spaniels”, and without any tendency towards aggression. It is an unusual case in which an official document records exactly the trait owners single out: reserve towards strangers, without suspicion and without nervousness.
Indoors this really is a very quiet dog: the Clumber sleeps a great deal, often snores, does not career about the house for the sake of it and rarely gives tongue without reason. Hence the sofa-dog label, which is inaccurate — in the field a different mode switches on, focused and methodical. Unlike the more energetic Welsh Springer Spaniel, the Clumber works slowly, but he works dense cover with remarkable thoroughness.
With children Clumbers are usually patient and gentle, and they live well alongside other dogs and cats, particularly if reared together. As a guard the breed is close to useless — far too good-natured for the role — though its bulk and deep voice can deter a stranger at the gate.
One domestic quirk deserves a mention: the habit of carrying something about in the mouth. Clumbers collect toys, sticks and slippers and “present” them to owners and visitors. This is not a behaviour problem but a breed mannerism, easier to live with than to fight.
Pros and cons of the Clumber Spaniel
The Clumber suits some households extremely well and others hardly at all, and the dividing line does not run where most people expect. It is not exercise: a breed content with a steady hour a day is manageable for a great many families. It is tolerance for mess, patience with a dog that thinks before it obeys, and a willingness to take health testing seriously before a puppy is ever chosen.
On the credit side, the Clumber is genuinely restful company: quiet, undemanding and dignified indoors, gentle with children and other animals, and steady enough that his mood does not swing with the weather. He is also unmistakable — few dogs draw as many questions on a walk. For anyone wanting an attached, level-headed companion rather than a sporting partner in perpetual motion, little else does the job as well.
On the debit side, the coat moults the whole year round and the dog drools; both are constants of life with the breed, not problems to be solved. Training asks for patience rather than firmness. The two serious drawbacks are of a different order: a long, well-documented list of inherited conditions, which makes the parents’ test results rather than the puppy’s looks the decisive question — and a rarity such that finding a responsible breeder takes real time and a willingness to wait for a litter.
Training and socialising the Clumber Spaniel
Clumbers are intelligent and remember well, but they are not among the dogs that obey a command for the sake of obeying it. They weigh up first what is in it for them — which is why only positive reinforcement works: praise, food, a game. Harsh handling destroys the working relationship and produces nothing in return.
Sessions are best kept short and consistent. The breed is more independent in its decision-making than, say, the Pyrenean Sheepdog (Smooth-Faced), which is accustomed to close cooperation with a handler. Early socialisation matters enormously: from puppyhood, introduce the Clumber to different people, sounds, surfaces and animals.
On exercise, the Kennel Club points to roughly an hour a day. Here, though, comes a caution most breeds do not carry: the Clumber has two documented inherited conditions that declare themselves precisely under exertion (both are set out below). Flat-out training to exhaustion is therefore out of place, and any episode of sudden weakness, incoordination or collapse after work is a reason to ring the vet at once — not to let the dog rest and think no more of it.
Care and grooming: ears, eyes and weight under daily watch
The priorities of Clumber care do not have to be guessed at: the Kennel Club states plainly what judges in the ring are asked to watch for in this particular breed. The Clumber sits in category 2 of Breed Watch — “breeds with visible health concerns linked to exaggerated conformation that need closer attention and monitoring”.
The list of points for special attention in the Clumber runs to four items, and each of them is in effect a line on the owner’s daily checklist:
eyelids not in normal contact with the eyeball — turned inwards or outwards;
obvious ear irritation;
excess weight;
incorrect hind conformation and/or poor rear movement.
Ears. Large, heavy, close-lying ears are poorly ventilated, and that makes an ideal setting for inflammation. Check them weekly for redness, odour and excess wax, clean them gently with a suitable ear lotion, and make sure they dry properly after a bath or a swim.
Eyes. Because of the way the eyelids are built, the eyes want a look over every day. The standard notes, incidentally, that a visible third eyelid is not to be counted a fault — so the things to watch for are redness, discharge and signs of irritation, rather than the mere visibility of the haw.
Coat. The Clumber moults all year round, and heavily during the seasonal moults. Brushing 2–3 times a week, and daily while the coat is coming out, lifts the dead hair and keeps mats from forming. Bath as required, usually once every 1–2 months. Hair between the pads and in the ear canal is trimmed away carefully.
Teeth and nails. Brush the teeth 2–3 times a week with a paste made for dogs; trim the nails once a month, or as they need it.

Frequently asked questions (FAQ)
Short answers to the questions asked most often — living in a flat, moulting, exercise, how hard the breed is to train and how long it lives — are gathered in the card at the top of this page. Three questions, though, keep coming back in a form that a single line cannot settle, and they are worth returning to here.
The first is why the height and weight given for the Clumber differ so widely from one reference work to the next. The answer is not that someone made an arithmetical slip: it is that the two registries publish different things. Read the sex-specific line from a single registry, and the confusion disappears at once; read a merged span, and you are reading a figure that no standard ever wrote down.
The second concerns what to do with a breeder’s answer about health screening. “The parents have been tested” is not the end of the conversation but the beginning of it, because the schemes described above produce numbers, not a pass mark: a hip score close to the breed’s five-year median means something quite different from one at the far end of the range. Ask what the results were, and ask to see them.
The third is whether so long a list of conditions means a short life. It does not follow automatically, and in this breed the two facts have been measured separately: the list of inherited problems is real and well documented, and the survival figures from the 2024 study sit alongside it without contradiction. Both things are true at once, and a page that reports only one of them is telling half the story.

FAQ
Is the Clumber Spaniel suited to life in a flat?
Yes. Indoors this is a very calm and quiet dog that does not need much space. It does need regular daily walks, though, and the heavy moulting and the drooling are more noticeable in a flat.
How long do Clumber Spaniels live?
A large British study published in 2024 puts median survival for the breed at 12.3 years (confidence interval 11.7–13.9). That study found no difference from crossbred dogs.
Why is the Clumber called a rare breed?
It is not a turn of phrase but an official status: the Kennel Club counts as vulnerable native breeds those with fewer than 300 registrations a year. In 2025, 160 Clumbers were registered in Britain.
Which tests should a breeder have done?
The Kennel Club treats hip and elbow screening, eye screening and the DNA test for EIC as the minimum, and adds a DNA test for PDP-1 deficiency at the higher tier. Ask to see the results, not merely to be told that testing was done.
How much exercise does a Clumber need?
About an hour a day at a steady pace is the guide. Flat-out work to the point of exhaustion does not suit the breed: it has two documented inherited conditions that declare themselves precisely under exertion.
Is the Clumber easy to train?
They are intelligent but independent and somewhat stubborn. Only positive reinforcement works, together with short consistent sessions and patience; harsh handling destroys the working relationship.
