25 Common Labrador Retriever Health Problems (And What to Do)

Labradors have been America’s favorite dog for over three decades, and I completely understand why. That wagging tail, the easy-going nature, the way they greet you like you’ve been gone for years.

But loving a breed doesn’t mean ignoring its risks. Labs are generally healthy, but they are not immune to serious problems.

A large UK study using veterinary clinical records found that 61.6% of Labrador Retrievers had at least one disorder recorded by their vet. That’s more than six in ten dogs.

This guide walks through 25 documented health problems in Labrador Retrievers. I’ll explain what causes each one, what to watch for, and how to manage it. No exaggeration, no filler, just what you actually need to know.

Why Labradors Face These Health Issues

Labs are a large, active breed with a genetic history built around retrieving game for hours in cold water. That athletic build carries hidden costs.

Their joints bear heavy loads throughout life, their appetite is famously difficult to control, and decades of popularity have led to inconsistent breeding standards across the world.

A study from the Royal Veterinary College found Labrador Retrievers had significantly increased odds of 12 out of 35 common canine disorders compared to other breeds, with osteoarthritis carrying the highest odds of all. That single finding shapes much of this article.

Labradors were also bred in three distinct lines over the years: field/working lines, show lines, and family pet lines. Each line carries a slightly different risk profile, since working dogs face more repetitive joint strain while show lines have sometimes been bred with less attention to structural soundness.

Knowing which type of Labrador you have, or plan to get, can actually help you anticipate which conditions on this list are most relevant to your dog.

Part 1: Joint and Bone Problems

1. Hip Dysplasia

This is the classic Labrador joint problem. The hip socket doesn’t form snugly around the ball of the thigh bone, causing looseness that leads to arthritis over time.

Cornell University’s veterinary college notes that canine hip dysplasia is common in medium and large breeds like Labradors, and that early diagnosis paired with timely treatment gives the best long-term outcome.

Cornell also describes a specialized diagnostic approach called the dorsolateral subluxation method, which images the hips while the dog kneels on the table, offering a more detailed view than a standard x-ray alone.

Surgical options range from a minimally invasive procedure performed in puppies as young as 12 to 20 weeks, to a full hip replacement in adult dogs with severe disease.

Watch for: a bunny-hop gait, difficulty rising, and reluctance to jump into the car.

2. Elbow Dysplasia

Similar to hip dysplasia but affecting the front legs. Malformed elbow joints cause pain, stiffness, and a shortened stride, usually appearing before a dog turns two years old.

Because Labradors are so physically active as puppies, this condition can go unnoticed for months, with owners mistaking early lameness for simple clumsiness or a minor sprain.

Screening x-rays before breeding are the main tool used to reduce this condition across the breed. Reputable breeders will happily share these results if asked.

3. Osteoarthritis (Degenerative Joint Disease)

Research from the Royal Veterinary College identified osteoarthritis as the single disorder with the highest increased odds in Labradors compared to other breeds. This isn’t a minor finding — it’s one of the strongest breed-specific risks documented.

I find this particularly important because arthritis is often written off as “just aging” in dogs, when in reality it’s a painful, manageable condition that deserves real treatment.

Weight control and joint supplements started early can meaningfully slow how fast arthritis progresses. Many vets now also recommend low-impact exercise like swimming to keep joints mobile without added strain.

4. Cranial Cruciate Ligament Rupture

This is essentially the canine equivalent of an ACL tear. It often happens gradually rather than from one dramatic injury, especially in overweight or middle-aged Labs.

A sudden inability to bear weight on a back leg, or persistent stiffness after rest, are common warning signs. Once one leg is affected, the opposite knee is also at meaningfully higher future risk.

Surgery is usually recommended for full recovery, since the joint remains unstable without it. Recovery typically takes eight to twelve weeks of restricted activity and physical therapy.

5. Osteochondrosis (OCD)

A developmental condition where cartilage doesn’t convert properly into bone, most often affecting the shoulder. Rapidly growing large-breed puppies, including Labs, are particularly prone to it.

Limiting high-impact exercise and jumping during the puppy growth phase helps reduce this risk.

6. Panosteitis

Sometimes called “growing pains,” this causes shifting leg lameness in young, rapidly growing Labradors, typically between five and twelve months old.

The good news is that panosteitis is usually self-limiting. Most dogs outgrow it completely by eighteen months to two years.

Part 2: Weight and Metabolic Conditions

7. Obesity

Labradors carry a genetic predisposition to overeating that most owners have never heard of. A University of Cambridge study found that around 25% of Labradors carry a mutation in the POMC gene, which makes them feel hungry more often and burn fewer calories at rest.

This single discovery changed how veterinarians talk to Lab owners about weight. It isn’t always about willpower on the owner’s part; it’s genuinely harder for some of these dogs to feel full.

The same research found that affected dogs also burn roughly 25% fewer calories at rest compared to Labs without the mutation. That combination of constant hunger and a slower metabolism is a tough one to manage.

Interestingly, the mutation is even more common among Labradors trained as assistance and service dogs, likely because their food motivation makes them easier to train.

Practical tip: measure meals precisely, use puzzle feeders to slow eating, and resist the guilt-driven urge to give extra treats.

8. Hypothyroidism

An underactive thyroid gland slows metabolism, often causing weight gain, hair thinning, and lethargy. It typically develops in middle age and is manageable with a daily medication for life.

Blood testing during routine senior checkups can catch this early, often before obvious symptoms appear.

9. Diabetes Mellitus

Less common than obesity but still documented in the breed, especially in overweight, middle-aged, and unspayed female Labs. Increased thirst, frequent urination, and unexplained weight loss are the classic early signs.

Managing weight throughout a Labrador’s life is one of the most effective ways to lower this risk, tying directly back to the breed’s genetic hunger predisposition.

Part 3: Digestive Emergencies and Internal Health

10. Gastric Dilatation-Volvulus (Bloat)

This is one of the most frightening emergencies in dog ownership. The stomach fills with gas and can twist on itself, cutting off blood flow within minutes.

Cornell’s veterinary college describes GDV as a life-threatening condition requiring immediate medical and surgical intervention, noting that large, deep-chested dogs face the highest risk.

Washington State University’s veterinary hospital notes that feeding smaller, more frequent meals rather than one large meal is one practical way to help lower the risk. They also recommend avoiding vigorous exercise right before or after meals.

Some vets now recommend a preventive procedure called gastropexy, which tacks the stomach to the abdominal wall so it cannot twist, even if it still fills with gas.

This is always an emergency. A distended, hard belly combined with unproductive retching means getting to an emergency vet immediately, not waiting until morning.

11. Exercise-Induced Collapse (EIC)

A genetic neuromuscular disorder that causes some Labradors to lose control of their hind legs after intense, high-excitement exercise like repeated retrieving.

The condition was first described in veterinary literature in 1993, and for years it was mistaken for heat intolerance or low blood sugar before researchers identified its true genetic cause.

The University of California, Davis Veterinary Genetics Laboratory offers a DNA test for the mutation, and breeders increasingly use it to avoid producing affected puppies. Roughly 30% of Labradors carry at least one copy of the gene.

Most episodes resolve within thirty minutes without lasting harm, but affected dogs need lifestyle adjustments to avoid triggering repeated collapses during high-intensity play or field work.

12. Chronic Diarrhea and Sensitive Stomach

Labs are notorious for eating things they shouldn’t, from socks to sticks. Combined with a genuinely food-motivated nature, this leads to more frequent digestive upset than many other breeds experience.

Consistent diet, portion control, and keeping tempting garbage out of reach go a long way here. If diarrhea lasts more than 48 hours or includes blood, a vet visit is warranted rather than waiting it out.

Part 4: Eye Conditions

13. Progressive Retinal Atrophy (PRA)

A group of inherited diseases that slowly destroy the light-sensing cells in the retina. Cornell’s Riney Canine Health Center lists Labrador Retrievers among the breeds carrying genetic variants that raise the risk of PRA.

Night blindness is usually the first sign, showing up as hesitation to go outside after dark or bumping into furniture in dim rooms. Dogs typically adjust well behaviorally, relying more on smell and memory as vision fades.

There’s no cure yet, but genetic testing before breeding helps responsible owners avoid producing affected litters.

14. Retinal Dysplasia

An early, congenital form of retinal disease that can appear alongside skeletal abnormalities in Labrador puppies. Affected litters were documented decades ago in veterinary research, and it remains a recognized inherited concern in the breed.

In some cases, this condition also involves shortened leg bones and delayed joint development, suggesting a shared genetic pathway between eye and skeletal formation in affected dogs.

15. Cataracts

Clouding of the eye’s lens that can appear at any age but is especially common in older Labradors. It ranges from a small spot that barely affects vision to complete blindness in advanced cases.

Surgery can restore vision in many cases, similar to how cataract surgery works in humans. Annual eye exams help catch cataracts while they’re still small and more easily managed.

16. Entropion and Ectropion

Entropion is an inward-rolling eyelid; ectropion is the opposite, where the lid droops outward. Both cause chronic irritation, and Labs can be affected by either, particularly around the lower lid.

Left uncorrected, entropion in particular can scratch the cornea repeatedly, leading to painful ulcers. A relatively straightforward surgery usually resolves both conditions permanently.

Part 5: Skin and Ear Conditions

17. Otitis Externa (Ear Infections)

Ear infections are the single most commonly recorded disorder in Labrador Retrievers, affecting roughly 10.4% of dogs in one large UK veterinary study.

Labs love water, and damp ear canals combined with their floppy ear shape create a perfect setup for bacterial and yeast growth. Drying ears thoroughly after every swim genuinely reduces how often infections occur.

A head shake, scratching at the ears, or a noticeable odor are the earliest warning signs. Catching an infection in its first day or two makes treatment much faster and less uncomfortable for the dog.

18. Increased Risk in Chocolate Labradors

Here’s something genuinely surprising. Research has found that chocolate-colored Labradors have a significantly higher prevalence of ear and skin disease, including otitis externa, than black or yellow Labs.

Scientists believe the same gene responsible for the chocolate coat color may also affect skin and coat health more broadly, though more research is ongoing.

If you own a chocolate Lab, it’s worth being a little more vigilant about ear checks and skin monitoring than you might be with a black or yellow littermate.

19. Atopic Dermatitis and Allergies

Environmental and food allergies show up as itchy skin, paw licking, and recurring skin infections. This condition often overlaps with, and worsens, ear infections in the same dog.

Identifying the specific trigger, whether pollen, dust mites, or a food ingredient, usually requires a structured elimination process guided by a veterinarian.

20. Hot Spots (Pyotraumatic Dermatitis)

A moist, red, rapidly spreading skin infection often triggered by constant licking or scratching at an itchy spot. These can appear and worsen within just a day or two.

Prompt cleaning and treatment prevent a small irritation from becoming a larger infected wound. Addressing the underlying allergy or irritation also helps prevent repeat episodes.

21. Lipomas (Fatty Tumors)

Soft, benign fatty lumps under the skin, notably common in Labradors according to multiple veterinary studies. Most are harmless, but any new lump should still be checked by a vet to rule out something more serious.

Larger lipomas near joints or in areas that restrict movement are sometimes removed, even though they aren’t cancerous, simply for comfort.

Part 6: Heart, Cancer, and Aging-Related Conditions

22. Tricuspid Valve Dysplasia

A congenital heart defect where one of the heart’s valves doesn’t form correctly, leading to blood flowing backward within the heart. It’s identified in Labradors more often than in many other breeds.

Mild cases may never cause symptoms, while severe cases can lead to heart failure over time. A cardiac ultrasound is the most reliable way to diagnose and grade its severity.

23. Cancer

According to the American Veterinary Medical Association, roughly one in four dogs will develop some form of cancer in their lifetime, and nearly half of dogs over age ten will be affected.

A Nationwide pet insurance study ranked Labrador Retrievers among the top five purebreds for cancer risk, with lymphoma being a particular concern for the breed. Hemangiosarcoma and mast cell tumors are also reported with some frequency.

Regular vet checkups that include feeling for unusual lumps, along with prompt biopsy of any new growth, remain the best early detection strategy available.

24. Laryngeal Paralysis

Usually a condition of older, large-breed dogs including Labradors. The muscles controlling the voice box weaken, making breathing loud and labored, especially during exercise or in warm weather.

A change in bark sound, noisy breathing, or reduced exercise tolerance in a senior Lab are worth mentioning to your vet. Surgery can significantly improve quality of life once a dog is diagnosed.

25. Degenerative Myelopathy

A slow, progressive spinal cord disease that resembles ALS in humans. It typically appears in older dogs, starting with hind-leg weakness that gradually worsens over months to years.

There’s no cure, but physical therapy and mobility aids can meaningfully extend a comfortable, active life. A genetic test can identify at-risk dogs before symptoms even begin.

How Long Do Labrador Retrievers Live?

A large UK study reported the median longevity of Labrador Retrievers at 12.0 years. Interestingly, that same research found chocolate-colored Labs had a shorter median lifespan than black or yellow dogs.

Genetics, weight management, and how quickly joint and metabolic issues are caught all influence where an individual dog lands within that range.

Working-line Labradors that stay lean and active throughout life often reach the higher end of this range, while overweight, sedentary dogs tend to develop complications earlier.

What This Means for Current and Future Lab Owners

Labradors remain one of the most rewarding breeds to own, and most live full, active lives. But a little proactive care changes outcomes significantly.

Here’s what genuinely helps:

• Ask breeders for hip and elbow screening results (OFA or PennHIP) on both parents.
• Keep your Lab lean for life — you should be able to feel, not see, the ribs.
• Learn the signs of bloat and know your nearest emergency vet clinic.
• Clean ears regularly, especially after swimming.
• Schedule annual vet visits that include a joint and weight assessment as your dog ages.
• Consider EIC genetic testing if you have a working or field-trial line Labrador.

A final thought: the very traits that make Labradors wonderful family dogs — their appetite for life, their love of water, their eagerness to please — are tied to some of the risks on this list. Understanding that connection helps you love them well for their whole life, not just the puppy years.

Frequently Asked Questions

What is the most common health problem in Labrador Retrievers? Ear infections are the most commonly recorded condition in veterinary studies, affecting roughly 10% of Labs, while osteoarthritis carries the highest increased risk compared to other breeds.

Why do Labradors gain weight so easily? Around a quarter of Labradors carry a genetic mutation in the POMC gene that increases hunger and lowers calorie burning, making weight control genuinely more difficult for these dogs than for many other breeds.

Are chocolate Labradors less healthy than black or yellow Labs? Research has found chocolate Labradors have a higher prevalence of ear and skin disease and a somewhat shorter median lifespan, though the exact biological reason is still being studied.

What is the most serious emergency Lab owners should know about? Bloat, or gastric dilatation-volvulus, is the most urgent. A hard, distended abdomen combined with unproductive retching requires immediate emergency veterinary care.

How can I reduce my Labrador’s risk of joint problems? Keep your dog lean throughout life, avoid excessive jumping and high-impact exercise as a puppy, and choose a breeder who screens both parents for hip and elbow health.
