All Dog Breeds >>Health of English Cocker Spaniel
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%). Common health issues with English Cockers are bite problems, skin allergies, shyness, cataracts, deafness (affecting 6.3% of the dogs of this breed), 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 which is the most common cause of canine arthritis in the hips. Patellar Lunation, also known as luxating patella, refers to the dislocation of the kneecap. Canine dilated cardiomyopathy is an adult onset condition which occurs when the heart muscle is weak and does not contract properly. It can lead to congestive heart failure, which is where fluid accumulates in the lungs, chest, abdominal cavities, or under the skin. Dilated cardiomyopathy is often accompanied by abnormal heart rhythms, or arrhythmias which can complicate treatment.
