Hip dysplasia, Collie eye anomaly (CEA), and epilepsy are considered the primary genetic diseases of concern in the breed at this time. Collie eye anomaly (CEA) is a congenital, inherited eye disease affecting Border Collies and other breeds involving the retina, choroid, and sclera. In Border Collies, it is generally a mild disease and rarely significantly impairs vision. There is now a DNA test available for CEA and, through its use, breeders can ensure that they will not produce affected pups. There are no genetic tests available for hip dysplasia or epilepsy, although careful breeding practices are known to lower the incidence of both.

Elbow dysplasia or Osteochondritis, deafness, and hypothyroidism may also occur in the breed. Dogs homozygous for the merle gene are likely to have eye and/or hearing problems. Responsible breeders do not mate merles to one another.

Neuronal ceroid lipofuscinosis (NCL) is a rare but serious disease. NCL results in severe neurological impairment and early death; afflicted dogs rarely survive beyond two years of age. The mutation causing the form of the disease found in Border Collies was identified by Scott Melville in the laboratory of Dr. Alan Wilton of the School of Biotechnology and Biomolecular Sciences, University of New South Wales, Sydney, Australia. There is no treatment or cure, but a DNA test is now available to detect carriers as well as affected dogs.

Trapped Neutrophil Syndrome (TNS) is a hereditary disease which inhibits the release of neutrophils produced in the bone marrow into the blood stream. Puppies affected with this disease will eventually succumb to infection. Because this is an autoimmune-deficiency disease the puppies present a variety of symptoms depending upon what infections they fall susceptible to, and so it has gone undiagnosed in the past. Once thought to be rare, it is now believed to be responsible for many cases of "fading puppies". There is no cure, but a DNA test is now available to detect carriers as well as affected dogs.

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.
