Abnormal development of the hip joints where the femoral head does not fit properly into the acetabulum, leading to laxity, cartilage damage, and progressive osteoarthritis. Hip dysplasia is polygenetic and influenced by environmental factors including growth rate, nutrition, and exercise during development. It is the most prevalent orthopaedic condition in Labrador Retrievers and a leading cause of mobility loss.

Prevention: Source puppies from OFA or PennHIP-tested parents with good or excellent hip scores. Maintain a lean growth rate during puppyhood — overfeeding accelerates dysplasia. Avoid high-impact exercise (jumping, hard running on pavement) until growth plates close at 18 months. Keep body weight optimal throughout life, as excess weight dramatically accelerates joint degeneration.

Symptoms: bunny-hopping gait when running, difficulty rising from lying position, reluctance to climb stairs or jump, decreased activity or exercise intolerance, audible clicking from hip joint, loss of thigh muscle mass, pain when hips are extended

A group of developmental abnormalities of the elbow joint including ununited anconeal process (UAP), fragmented medial coronoid process (FCP), and osteochondritis dissecans (OCD). These conditions cause joint incongruity, pain, and progressive arthritis. Often bilateral, affecting both elbows. Labs are among the most commonly affected breeds.

Prevention: Choose breeders who screen for elbow dysplasia. Control growth rate in puppyhood with appropriate feeding. Avoid repetitive high-impact activities during skeletal development. Maintain healthy weight. Early surgical intervention for FCP or OCD can improve long-term outcomes significantly.

Symptoms: front limb lameness (often worse after rest), stiff gait after lying down, reluctance to fully extend the elbow, swelling around the elbow joint, shifting weight to hind legs, decreased willingness to play or exercise

A genetic neuromuscular condition where affected Labs experience episodes of muscle weakness, incoordination, and collapse during intense exercise. Episodes typically occur after 5-25 minutes of strenuous activity, particularly in excited or highly driven dogs. Dogs recover fully within 5-30 minutes of rest. Rarely fatal, but life-threatening episodes can occur in extreme heat.

Prevention: DNA testing identifies carriers and affected dogs. All breeding Labs should be EIC-tested. Affected dogs can live normal lives with exercise modification — avoid intense, sustained exercise (repeated hard retrieves, sprinting) especially in warm weather. Moderate, steady exercise is generally well-tolerated.

Symptoms: wobbly hind legs during intense exercise, wide-based swaying stance, dragging of hind feet, collapse to the ground, elevated body temperature during episodes, full recovery within 5-30 minutes of rest

Labrador Retrievers carry a deletion mutation in the POMC gene that disrupts appetite regulation, making them perpetually hungry and highly prone to weight gain. Studies show approximately 25% of Labs carry this variant. Obesity in Labs is not simply an owner management issue — it has a strong genetic component. Excess weight contributes to joint disease, diabetes, respiratory compromise, reduced lifespan (up to 2 years shorter), and decreased quality of life.

Prevention: Measure every meal precisely using a kitchen scale (cups are inaccurate). Feed a calorie-controlled diet appropriate for the dog's ideal weight, not current weight. Eliminate or strictly limit treats, using portions of the daily kibble ration for training rewards. Do not free-feed. Weigh your Lab monthly. A landmark Purina study showed that Labs kept at ideal body condition lived a median of 1.8 years longer than their overfed littermates.

Symptoms: inability to feel ribs without pressing firmly, no visible waist when viewed from above, fat deposits over spine and base of tail, waddling gait, exercise intolerance, difficulty grooming hindquarters, excessive panting

A group of inherited degenerative diseases affecting the photoreceptor cells in the retina, leading to progressive vision loss and eventual blindness. The prcd-PRA form is most common in Labs. Night blindness is typically the first sign, progressing to complete blindness over months to years. There is no treatment, but dogs adapt remarkably well to vision loss in familiar environments.

Prevention: DNA testing for prcd-PRA is available and should be mandatory for any breeding dog. Carriers can be identified before breeding. Ask your breeder for proof of PRA-clear status for both parents. Annual ophthalmologic exams can detect early retinal changes.

Symptoms: night blindness (bumping into things in dim light), dilated pupils, increased eye shine (tapetal reflection), reluctance to enter dark rooms, progressive daytime vision loss, bumping into furniture rearranged from familiar positions
