British royalty favorite and one of the first pure breeds registered in the US, the Clumber Spaniel, modestly reveals its dignity, charm and professional ethics. This modest show dog is Ch. Clussexx Country Sunrise, the first Clumber who won the Westminster exposition in 1996. 
Long, short and heavy, the Clumber Spaniel has marked and heavy eyebrows, a deep chest and strong bone structure. Its color is mostly white with lemon or orange colored patches; there can be freckles, but the fewer spots the better. The male stands at 48 – 50 cm, the female from 43 to 48 cm; the male weighs between 35 and 42 kg, the female between 26 and 35 kg. For the FCI the ideal weight is 34 kg for males and 29.5 kg for females. The Clumber’s head is massive, with wide ears in the shape of vine leaves, low inserted; the upper portion of the skull, flat, and the occipital, pronounced, with a defined stop, and wide and deep muzzle; the nose, brown colored (including beige and cherry tonalities). The neck is long with some dewlap; the back, straight and firm; the lumbar area only slightly arched. The forequarters, straight and short, with close elbows; the carpus very slightly sloped; the feet large with thick pads; the hindquarters very well angled. In essence, the body is rectangular. The coat is straight and thick, soft in texture; the hair is longer at the neck, limbs, abdomen, tail and ears.
The Clumber virtues deserve a well nourished buffet. The Clumber lacks few things, except popularity; it is good, kind and patient, which needs attention, but expects little rewards. 
A docile, balanced Spaniel, endowed with a lot of patience and understanding, the Clumber is not very popular despite all its virtues. It is perhaps suspicious that the Clumber is so good; it has no bad habits, it is not malicious, nor is it hipernervous at home. The Clumber loves children, and loves them naturally. Some say that it is lazy and prefers not to move. The owner should stimulate its activity, since it is an innate hunter and loves to be in the field.
The newborn Clumber weighs between 340 and 500 g, in average, and litters are usually four to six puppies. The Clumber puppy grows quickly at first, for which its diet quality is important. Fortunately they like to eat, and it is rarely a problem to make it eat. Although it grows quickly, it matures slowly, not reaching maturity until after three years. Due to this fact, it is not recommendable to give it vitamins and minerals, since it could lead to abnormal growth. The young Clumber is an active and curious dog, and exercise and education should be programmed early.
For a heavy dog as the Clumber, 12 to 14 year longevity is promising and impressive. 
Since there it is little demand for the Clumber Spaniel, only the best specimens are bred. Therefore, there are very few genetic and/or hereditary problems in the breed. 
Due to selective and limited breeding, the Clumber lacks hereditary problems. Entropion can occur, and in less degree ectropion, which should be controlled. Hip dysplasia is reported, for which X – rays should be taken. Likewise, inferior prognathism and missing teeth should be controlled. The most important thing the owner should avoid is overfeeding and providing moderate daily exercise (ideally field work and/or walks) throughout the dog’s life. Otherwise, this long, short and heavy dog is prone to developing all sorts of joint and disk problems, and its vital organs can be exposed to too much unnecessary stress. The third eyelid is quite pronounced and perfectly normal in a Clumber. The hair in this athlete requires minimal care, although it should be brushed thoroughly several times per week, especially after a country outing. The Clumber can live to 14.
The Clumber puppies can be less active than other breeds, although breeders have no problems keeping them occupied. As any puppy, it is curious and playful.
