Cockers are renowned for their stubborn temper but can be easily trained and make a good medium-sized family pet. They don't like being alone. They will also bond strongly to an individual person in a family. Cockers are noted for their optimism, intelligence and adaptability. The breed is extremely loyal and affectionate; bonding very well with the family members. They rank 18th in Stanley Coren's The Intelligence of Dogs, being of excellent working/obedience intelligence.
It has been proposed that there is a link between coat colour and temperament. This link could be the colour pigment melanin, which is bio chemically similar to chemicals that act as transmitters in the brain. Cocker Spaniel behaviour has been studied in more detail than any other breed.
A study made by the University of Cambridge involving over 1,000 Cocker Spaniel households throughout Britain concluded that solid colour Cockers were more likely to be aggressive in 12 out of 13 situations. Red/golden Cockers were shown to be the most aggressive of all, in situations involving strangers, family members, while being disciplined, and sometimes for no apparent reason. A study by Spanish researchers at the Autonomous University of Barcelona revealed a similar link between golden Cockers and aggression. Males were also more likely to be aggressive. The study found the English Cocker Spaniel to have the highest level of owner- and stranger- directed aggression compared to other breeds.
Cocker spaniels and "Rage Syndrome"
Rage Syndrome is described as when a dog attacks suddenly and savagely, without any warning and during the attack the dog often has a glazed look and appears to be unaware of its surroundings. Studies have found it is more common in solid colored Cockers than in particolors and also more common in darker colored Cockers than lighter coloured Cockers, being most common in solid orange and black colored spaniels. Male orange spaniels are not recommended as a family pet and should never be left alone with children. Rage syndrome is most often associated with the Show Cocker Spaniel breed, although cases have been found in other breeds and cases are relatively rare even within the Cocker Spaniel breed. Rage syndrome cannot be accurately predicted and can only be diagnosed by EEG or genetic testing and these tests are not conclusive.
English Cocker Spaniels in UK and USA/Canada have an average lifespan of 11 to 12 years, which is a typical longevity for purebred dogs, but a little less than most other breeds of their size. The English Cocker Spaniel typically lives about a year longer than the smaller American Cocker Spaniel.
In a 2004 UK Kennel Club survey, the most common causes of death were cancer (30%), old age (17%), cardiac (9%), and "combinations" (7%). In 1998 and 2002 USA/Canada Health Surveys, the leading causes of death were old age (40%) and cancer (22%).
Morbidity
Common health issues with English Cockers are bite problems, skin allergies, shyness, cataracts, deafness, aggression towards other dogs, and benign tumours.
Some uncommon health issues that can also have an effect on English Cocker Spaniels include canine hip dysplasia, patellar lunation, canine dilated cardiomyopathy, and heart murmurs. Hip dysplasia is an abnormal formation of the hip joint. Patellar Lunation, also known as luxating patella, refers to the dislocation of the kneecap. Canine dilated cardiomyopathy involves heart failure.
