Labradors are somewhat prone to hip and elbow dysplasia, especially the larger dogs, though not as much as some other breeds. Hip scores are recommended before breeding and often joint supplements are recommended. They also suffer from the risk of knee problems. A luxating patella is a common occurrence in the knee where the knee dislocates and goes back into place. Eye problems are also possible in some Labradors, particularly progressive retinal atrophy, cataracts, corneal dystrophy and retinal dysplasia. Dogs which are intended to be bred should be examined by a veterinary ophthalmologist for an eye score. Hereditary myopathy, a rare inherited disorder that causes a deficiency in type II muscle fibre. Symptoms include a short stilted gait or "bunny hopping," and in rare cases ventroflexion of the neck accompanied by a kyphotic posture. There is a small incidence of other conditions, such as autoimmune diseases and deafness in Labradors, either congenitally or later in life. Labradors often suffer from exercise induced collapse, a syndrome that causes hyperthermia, weakness, collapse, and disorientation after short bouts of exercise. Labradors like to eat, and without proper exercise can become obese. Laziness also contributes to this. Obesity is a serious condition and can be considered the number one nutritional problem with dogs. Therefore Labradors must be properly exercised and stimulated. A healthy Labrador can do swimming wind sprints for two hours, and should keep a very slight hourglass waist and be fit and light, rather than fat or heavy-set. Obesity can exacerbate conditions such as hip dysplasia and joint problems, and can lead to secondary diseases, including diabetes. Osteoarthritis is common in older, especially overweight, Labradors. Labradors should be walked twice a day for at least half an hour.

Health

Common health issues with English Cockers are bite problems, skin allergies, shyness, cataracts, deafness (affecting 6.3% of the dogs of this breed[27]), 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 luxation, 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. Cocker Spaniels can present with a nutritional form of dilated cardiomyopathy that is associated with low blood concentrations of the amino acid taurine. This form of dilated cardiomyopathy is in many cases reversible if the dog receives taurine supplementation.
