If there is a single health topic that every Labrador owner should understand, it is obesity. Research from the University of Cambridge identified a mutation in the POMC gene that affects roughly one in four Labradors, making them feel perpetually hungry and less able to sense fullness after a meal. This genetic quirk, combined with the breed's enthusiastic appetite and the human tendency to equate treats with love, means that Labradors gain weight more easily than almost any other breed.

Obesity is far more than a cosmetic concern. Excess weight accelerates joint deterioration, increases the risk of diabetes, contributes to respiratory difficulty, and shortens lifespan. A landmark study by Purina demonstrated that Labradors kept at a lean body condition lived nearly two years longer on average than their overweight littermates. Two additional years with your dog is a profound reward for something as straightforward as portion control.

Preventing obesity begins with accurate feeding. Use a kitchen scale or measuring cup, follow your veterinarian's caloric recommendation rather than the bag label, and account for every treat and table scrap in your dog's daily calorie budget. Training treats should be tiny, and low-calorie options such as small pieces of carrot or blueberry work well for most Labradors.

Body condition scoring is a practical skill for owners to learn. You should be able to feel your Labrador's ribs with light pressure, see a visible waist when viewed from above, and notice a tuck in the abdomen when viewed from the side. If these landmarks disappear, it is time to reduce portions and increase activity before the extra weight takes a toll on joints and organs.

Like many large breeds, Labrador Retrievers are susceptible to hip dysplasia and elbow dysplasia. These developmental conditions result in joints that do not fit together smoothly, leading to chronic pain, reduced mobility, and arthritis over time. Reputable breeders screen their dogs through OFA or PennHIP evaluation and only breed individuals with passing scores, but screening does not eliminate risk entirely because the conditions involve multiple genes and environmental factors.

Maintaining lean body weight during puppyhood is especially critical. Puppies that grow too quickly or carry excess weight place undue stress on developing joints, increasing the likelihood that mild dysplasia becomes clinically significant. Puppy-specific diets formulated for large breeds control calcium and calorie levels to promote steady, appropriate growth. Avoid high-impact activities such as repetitive ball-fetching on hard surfaces until growth plates have closed, typically around 12 to 18 months of age.

Exercise-induced collapse (EIC) is a genetic condition unique to certain Labrador lines. Dogs with EIC appear normal at rest and during moderate activity but develop weakness and wobbling in the hind legs after five to twenty minutes of intense exercise, particularly in warm weather. Episodes are frightening to watch but are usually not life-threatening if the dog is allowed to rest and cool down. A DNA test can identify carriers and affected dogs, and breeders should test all breeding stock.

Cranial cruciate ligament (CCL) injuries are another orthopedic concern. Labradors are among the breeds most commonly presented for CCL repair. The combination of a high activity level, muscular build, and potential joint laxity creates conditions under which the ligament can partially or fully tear. Surgical options such as TPLO or TTA provide good outcomes in most cases, but prevention through weight control and balanced exercise is always preferable to treatment.

Progressive retinal atrophy (PRA) is an inherited eye disease that leads to gradual vision loss and eventual blindness. In Labradors, the most common form is prcd-PRA, for which a reliable DNA test exists. Responsible breeders test their dogs before breeding and do not produce litters from two carriers. If your Labrador is diagnosed with PRA, the progression is typically slow enough that dogs adapt well, but your veterinarian can advise on environmental modifications to keep a visually impaired dog safe and comfortable.

Cataracts can also develop in Labradors, sometimes in conjunction with PRA and sometimes independently. Routine eye examinations by a veterinary ophthalmologist can detect lens changes before they affect vision significantly. In many cases, cataract surgery restores excellent vision and is well tolerated by otherwise healthy dogs.

Ear infections are extremely common in Labradors. Their floppy ears trap moisture, especially after swimming or bathing, creating ideal conditions for bacterial and yeast overgrowth. Chronic ear infections cause pain, head shaking, odor, and can eventually damage the ear canal if left untreated. Preventive care includes drying the ears thoroughly after water exposure, weekly inspection for redness or discharge, and gentle cleaning with a veterinary-approved ear solution.

Allergies, both environmental and food-related, often manifest as recurrent ear infections in Labradors. If your dog's ears seem to be in a constant cycle of infection and treatment, your veterinarian may recommend allergy testing or an elimination diet to identify the underlying trigger.

Labrador Retrievers typically live 10 to 13 years, with chocolate Labradors trending toward the shorter end of that range according to a 2018 study from the University of Sydney. The study also found that chocolate Labs had higher rates of ear infections and skin conditions, possibly because a smaller gene pool for the color leads to less genetic diversity in health-related traits.

Feeding a high-quality, life-stage-appropriate diet is one of the most impactful decisions an owner can make. Large-breed puppy food supports controlled growth, adult formulas maintain lean muscle, and senior diets often include joint-supportive ingredients and adjusted calorie levels. Avoid free-feeding. Instead, offer measured meals two or three times per day and adjust quantities based on your dog's body condition rather than appetite alone.

Exercise is essential for a breed originally developed for all-day fieldwork. Most adult Labradors thrive with 60 to 90 minutes of daily physical activity, which can include walking, swimming, retrieving games, and scent work. Swimming is particularly beneficial because it provides cardiovascular exercise and muscle strengthening without the joint impact of running on hard surfaces.

Preventive veterinary care should include annual exams with bloodwork, dental assessments, and discussion of weight trends. After age seven, semi-annual visits allow earlier detection of age-related conditions such as hypothyroidism, kidney disease, and cancer. Discuss a breed-appropriate vaccination and parasite prevention schedule with your veterinarian, taking into account your dog's lifestyle and geographic risk factors.

Bloat, or gastric dilatation-volvulus (GDV), is less common in Labradors than in deep-chested breeds like Great Danes, but it does occur. Feeding smaller, more frequent meals and avoiding vigorous exercise immediately after eating are simple precautions that reduce the risk.
