Because Clumber Spaniels are large boned and fast growing, they can suffer from temporary lameness from between six and twelve months of age, with this lameness subsiding when bone growth is complete. Another common condition that the breed suffers from are impacted
anal sacs and the dog may require them to be emptied by a
veterinarian. The final common condition that the breed has is heat sensitivity: if Clumber Spaniels are left without shade, they can become uncomfortably hot and dehydrated. In addition, Clumbers often have difficulties conceiving and giving birth, and may require
caesarian sections. Some dogs may suffer from sensitivity to anaesthesia. The most common severe health conditions in the Clumber Spaniel are entropion/ectropion eye conditions, spinal disc herniation and hip dysplasia. A 2024 UK study found a life expectancy of 12.3 years for the breed compared to an average of 12.7 for purebreeds and 12 for
crossbreeds.
Entropion/Ectropion Entropion is the inward rolling of the
eyelid, commonly the lower lid. This in turn irritates the
cornea of the eye and can cause visual impairment. It is a hereditary disorder seen in both
English and
American Cocker Spaniels,
King Charles Spaniels,
English Springer Spaniels plus a variety of non
spaniel breeds.
Ectropion is the outward rolling of the eyelid, which abnormally exposes the eye, resulting in irritation. Because of the increased exposure, the dog can develop allergic or bacterial
conjunctivitis or
keratoconjunctivitis sicca also known as dry-eye syndrome. It is most commonly found in breeds with exaggerated facial features such as the
Boxer,
Bloodhound,
Gordon Setter as well as the English and American Cocker Spaniels, and the English Springer Spaniel. The treatment for ectropion varies depending on the severity of the condition.
Hip dysplasia Hip dysplasia is a hereditary condition which occurs in most dog breeds to some extent, according to scores from a 2001
UK Kennel Club scheme, the Clumber Spaniel has the second worst breed mean scores. Furthermore, a survey conducted by the Orthopedic Foundation for Animals found that 45.7% of Clumber Spaniels tested were affected by the condition. Initial signs are usually first noted when the dog is between five and twelve months old, and may include a swaying hindleg
gait, hindleg lameness, muscle wastage around the hindquarters, reluctance to and fatigue during exercise, inability to climb stairs or jump up. The dog can appear hunched up with an arched back, and in the very worst cases may wince with pain when moving its hindlegs. Medical treatment can vary from the administration of painkillers to surgical correction depending on the severity of the condition. == History ==
