What Great Pyrenees Owners Should Watch for—and When to Act

What Great Pyrenees owners should watch for—and when to act.

Great Pyrenees health risks at a glance

This guide concerns the Great Pyrenees dog breed, not the Pyrenees mountain region or every breed with “Pyrenean” in its name.

Great Pyrenees are often described as generally healthy dogs, but they may be predisposed to inherited or breed-associated conditions. Predisposition is not a diagnosis or prediction: an individual dog may never develop any of the problems discussed here.

The concerns repeated most consistently in the available breed-health material are:

• Gastric dilatation-volvulus, or GDV
• Hip and elbow dysplasia
• Patellar luxation
• Entropion
• Cataracts

Other reported concerns include osteosarcoma, Addison’s disease, degenerative myelopathy, Wobbler syndrome, neuronal degeneration, von Willebrand disease, allergies and heart disease. These associations are not equally well supported, and the available sources do not provide reliable prevalence estimates. It is therefore not possible to rank them honestly from most to least common.

A commonly cited Great Pyrenees lifespan is approximately 10–12 years, although an individual dog may live for a shorter or longer period. PetMD’s breed guide supplies that range and lists orthopedic, eye, neurologic and digestive conditions reported in the breed (PetMD’s Great Pyrenees health and care guide).

For owners, the practical priority is not memorizing a disease inventory. It is recognizing changes and choosing the right level of action:

1. Go now for possible GDV, fainting or collapse, breathing difficulty, a seizure, heavy bleeding or serious trauma.
2. Book a veterinarian promptly for changes that are painful, persistent, recurring or worsening.
3. Use routine visits to discuss preventive care, screening and gradual trends in weight, mobility, vision or stamina.

Symptoms rarely identify one disease by themselves. Limping may result from a paw injury, joint disease, a growth-related disorder, spinal disease or bone pain. Vomiting can accompany a minor digestive upset, a systemic illness or an emergency. Lethargy is similarly nonspecific. Observing these signs is valuable; diagnosing their cause at home is not safe.

Go now: recognize bloat and GDV

Gastric dilatation-volvulus is the most important immediate emergency for Great Pyrenees owners to recognize. In GDV, the stomach expands with gas or other contents and may twist. The twisting can disrupt circulation and compromise blood flow, making the condition life-threatening.

Great Pyrenees are deep-chested dogs, and breed-health guides repeatedly identify that body shape as a reason to pay particular attention to GDV. Warning signs may include:

• A visibly swollen, enlarged or tight abdomen
• Repeated retching or dry heaving that produces nothing
• Restlessness or inability to settle
• Excessive drooling
• Apparent abdominal pain
• Standing with the front end lowered and the rear end raised, sometimes called a prayer-like posture

Veterinary clinic guidance for the breed describes GDV as an emergency and lists unproductive retching, restlessness, abdominal enlargement and the prayer-like posture among its warning signs (Dunkirk Animal Hospital’s Great Pyrenees guide).

If your Great Pyrenees has a swollen or tight abdomen with repeated unproductive retching—or several signs strongly suggesting GDV—leave for an emergency veterinary hospital immediately. Do not wait to see whether the dog improves, and do not delay departure while trying home remedies.

The consequences of waiting on a true GDV are much more serious than the inconvenience of an emergency examination that rules it out.

Possible GDV belongs in the go-now tier. Other general canine emergencies include:

• Fainting, collapse or inability to rouse the dog
• Difficulty breathing
• Pale, blue, grey or otherwise abnormal-looking gums
• A seizure
• Heavy or uncontrolled bleeding
• Serious trauma, such as a road accident or significant fall

The Paw Primer watch, book and go-now framework places a swollen, tight canine abdomen with restlessness and unproductive retching alongside collapse, seizures, breathing difficulty, heavy bleeding and serious trauma as signs requiring immediate action.

A veterinarian may discuss preventive gastropexy, a surgical procedure that secures the stomach to reduce the possibility of twisting. It is an individualized option to discuss according to the dog’s circumstances, medical history and veterinary assessment—not a requirement for every Great Pyrenees.

You may encounter recommendations about splitting meals, changing bowl height, using slow feeders or restricting exercise around meals. The evidence supplied for this guide does not establish how effectively those practices prevent GDV. They should not be treated as guarantees or as substitutes for recognizing emergency signs.

Joint, bone and mobility problems

Because Great Pyrenees are large dogs, changes in gait and mobility can significantly affect daily comfort and independence. Stiffness, limping, hopping or difficulty rising deserves attention, but the visible pattern alone cannot establish which joint, bone, muscle or neurologic condition is responsible.

Hip and elbow dysplasia

Hip and elbow dysplasia involve abnormal joint development. An affected joint may deteriorate and develop arthritis, contributing to pain, stiffness, lameness, difficulty rising and reduced function.

Possible signs include:

• Stiffness after rest
• Reluctance to climb stairs or enter a vehicle
• Difficulty standing up
• Persistent or recurring limping
• Reduced willingness to walk, run or play
• A shortened stride
• Persistent “bunny-hopping,” in which the rear legs move together

Bunny-hopping can occur with hip discomfort, but it does not diagnose hip dysplasia.

Heredity may contribute to dysplasia. Body condition, nutrition, growth and activity may also affect joint health or the severity of clinical problems. It is inappropriate to assign one cause to an individual dog without considering its development, history and current condition.

A veterinarian may use physical examination and X-rays to evaluate the hips or elbows. Imaging may also be appropriate when investigating other orthopedic problems, but the veterinarian should determine which body areas and views are needed. Veterinary breed guidance connects hip and elbow dysplasia with arthritis, stiffness, lameness and difficulty rising while discussing imaging and weight management as parts of evaluation and care (Cascade Veterinary Clinics’ Great Pyrenees guide).

Patellar luxation

Patellar luxation occurs when one or both kneecaps move out of their normal position. An owner may notice:

• Intermittent skipping
• A few hopping steps followed by normal movement
• Briefly carrying or favoring one rear leg
• Recurring hind-leg lameness

Repeated displacement may contribute to inflammation, instability and arthritis. Severity varies, and not every dog requires the same treatment. A veterinarian must distinguish patellar luxation from ligament injury, hip disease, paw pain and other causes of skipping.

Orthopedic problems in puppies and adolescents

Lameness in a growing Great Pyrenees should not automatically be dismissed as harmless “growing pains.” Young dogs can develop injuries, dysplasia and other orthopedic disorders that require assessment.

Osteochondritis dissecans is a joint-development disorder associated in clinic breed guides with overly rapid growth. Eosinophilic panosteitis is described as a painful condition in young dogs that can produce lameness shifting from one leg to another. Even if a condition may eventually resolve, an owner cannot confirm its cause from the gait pattern or safely assume puppy limb pain is benign.

Controlled development is one reason to feed an appropriate large-breed puppy diet, avoid overfeeding and refrain from adding calcium unless a veterinarian specifically recommends it. These measures support appropriate growth but cannot guarantee that a puppy will avoid inherited or developmental orthopedic disease.

Persistent pain and osteosarcoma

Nevertheless, osteosarcoma is a serious possible cause of persistent lameness or focal leg pain in large and giant dogs. Changes that warrant investigation include continuing pain in one area, swelling or a lump on a limb, worsening lameness and an unexplained decline in activity. Breed guidance describes osteosarcoma as an aggressive, painful bone tumor and identifies lameness and leg pain as possible early signs (Sutton Animal Hospital’s Great Pyrenees health guide).

Arrange prompt veterinary attention if a dog:

• Cannot bear weight on a limb
• Appears to be in marked pain
• Declines rapidly
• Develops focal swelling or a painful lump
• Has limping that persists or repeatedly returns

Repeatedly “watching for a few more days” is not an adequate plan when pain continues or the problem keeps returning.

For dogs with established mobility limitations, broad supportive measures may include maintaining a healthy body condition, following veterinarian-guided activity recommendations, adding traction to slippery flooring, and using ramps or supportive bedding. Ask a veterinarian before selecting pain medicines or supplements; a product appropriate for one dog may be unsuitable or dangerous for another.

Eye disorders and signs of discomfort

Entropion and cataracts are the eye problems reported most consistently in the available Great Pyrenees breed guides.

Entropion is an eyelid abnormality in which the lid rolls inward. Hair or eyelashes may rub against the eye, causing irritation, pain or corneal injury. An affected dog may squint, hold the eye shut, tear excessively or rub at the face.

Cataracts create opacity within the lens and may interfere with vision. Owners may notice cloudiness, hesitation in dim light, bumping into objects or reduced visual confidence. Not every cloudy-looking eye is a cataract, however, and appearance alone cannot determine the cause.

Additional reported concerns include:

• Distichiasis, in which extra eyelashes may contact and irritate the eye
• Canine multifocal retinopathy, an inherited retinal disorder reported in some breed material

Not every source lists these additional disorders, so they should not be treated as equally established or equally likely. Some eyelid and lens disorders may be treated surgically. PetMD reports no current treatment for canine multifocal retinopathy, although condition-specific DNA testing may provide information about inherited status.

Book an examination if you notice:

• An eye held partly or fully shut
• Persistent watering or discharge
• Redness
• Cloudiness
• An eyelid that appears to roll inward or sit abnormally
• Repeated rubbing at the eye or face
• A noticeable vision change

A painful-looking eye should be assessed promptly because some causes can threaten comfort or vision if treatment is delayed. Do not attempt to identify an eye disorder from photographs or appearance alone.

An eye examination and a DNA test answer different questions. The examination evaluates the dog’s current eye health. A condition-specific genetic test may indicate whether the dog carries or inherited a tested variant.

Neurologic, hormonal, bleeding and other reported concerns

The following conditions appear in one or more Great Pyrenees health guides, but they are not necessarily common, equally likely or unique to the breed. They form a secondary list of reported possibilities—not a checklist of diseases every owner should expect.

Degenerative myelopathy

Degenerative myelopathy is described in clinic breed guides as a progressive condition involving hind-leg weakness. Signs may advance over time and can eventually include paralysis and loss of normal function. The clinic sources used for this guide state that there is no cure.

Possible observable changes include:

• Scuffing or dragging the rear paws

• Hind-leg weakness

• Difficulty rising
• An unsteady rear gait
• Increasing loss of mobility

These signs are not specific to degenerative myelopathy. Arthritis, spinal compression, injury and other neurologic or orthopedic disorders can look similar.

Wobbler syndrome

Wobbler syndrome is described as narrowing or instability involving the neck vertebrae that affects spinal cord function. It may cause poor foot placement, stumbling, an unstable hind end or falls. Affected dogs may look weak, clumsy or unusually hesitant when turning.

New stumbling, falls, paw dragging or hind-leg weakness should be evaluated rather than attributed automatically to age. Examination and diagnostic testing are needed to distinguish joint pain from spinal or neurologic disease. Dunkirk Animal Hospital’s guide discusses both Wobbler syndrome and degenerative myelopathy among reported neurologic concerns in Great Pyrenees.

Neuronal degeneration

PetMD reports neuronal degeneration as an inherited, progressive nervous-system disorder in the breed. Signs are described as beginning before one year of age and potentially progressing from stumbling or paw dragging to an inability to stand or walk.

Those early signs overlap with injuries, orthopedic disorders and other neurologic conditions, so they require veterinary investigation. A relevant genetic result may help clarify inherited status, but it is not a substitute for examining a symptomatic young dog.

Von Willebrand disease and unusual bleeding

Von Willebrand disease is reported in some clinic guides as an inherited clotting disorder. A possible clue is unusual or excessive bleeding after an injury, operation or other procedure. The available evidence does not justify calling it common in Great Pyrenees or estimating how often it occurs.

Heavy or uncontrolled bleeding is an emergency. Less dramatic but unusual bleeding, such as prolonged oozing after a minor injury, also warrants veterinary attention. Before a planned procedure, a veterinarian may consider clotting evaluation based on the dog’s history, available family information and examination.

Addison’s disease

Addison’s disease is an adrenal hormone disorder that can resemble other illnesses. Possible signs include:

• Weakness
• Lethargy
• Intermittent vomiting or diarrhea
• Appetite changes
• An unexplained decline in condition

These symptoms have many possible causes and cannot confirm Addison’s disease. Diagnosis requires veterinary blood testing. Lebanon Small Animal Clinic’s breed profile lists weakness, lethargy and intermittent gastrointestinal upset as possible signs and identifies bloodwork as part of confirmation (Lebanon Small Animal Clinic’s Great Pyrenees profile).

Heart disease

Some clinic breed guides list heart disease among possible Great Pyrenees concerns. Observable signs may include easy tiring, coughing, abdominal swelling or fainting. None identifies a particular heart condition, and each can have noncardiac causes.

Fainting, collapse or breathing difficulty belongs in the go-now tier. A gradual decline in stamina or recurring cough should also be discussed with a veterinarian rather than assumed to be normal aging.

Osteosarcoma and unexplained decline

Osteosarcoma is the cancer concern emphasized most consistently in the broader clinic material. Persistent lameness, focal leg pain, a new lump or an unexplained decline warrants investigation, even though a more ordinary condition may ultimately be responsible.

Do not massage a painful swelling aggressively or repeatedly test the limb at home. Record where the problem is located and how it affects movement, then let the veterinarian determine whether examination, imaging or sampling is appropriate.

Allergies and recurring skin or ear problems

Allergies are one possible explanation for persistent:

• Itching
• Paw licking or chewing
• Face rubbing
• Skin irritation
• Recurring ear inflammation

The evidence does not establish that allergies are especially common in Great Pyrenees. Parasites, infections, foreign material and other skin conditions can produce similar signs. Persistent itching, odor, discharge, broken skin or recurring ear trouble should be examined rather than treated indefinitely with assorted home products.

Ordinary canine health problems still matter

A breed-health guide naturally focuses on reported predispositions, but Great Pyrenees can also develop ordinary canine problems. Dental disease, obesity, parasites, infectious respiratory illness and urinary infections remain relevant without necessarily being distinctive breed risks.

This distinction matters. Calling every canine ailment a Great Pyrenees predisposition can create unnecessary alarm and distract from the practical task: observing changes, obtaining preventive care and investigating signs that persist.

A symptom-to-action guide for owners

Use observable signs—not an assumed diagnosis—to decide what to do. If a sign appears to fit more than one urgency tier, use the higher level.

Action level	Observable signs	What to do
Go now	Swollen or tight abdomen with repeated dry heaving; fainting or collapse; breathing difficulty; seizure; heavy bleeding; serious trauma	Leave for an emergency veterinary hospital or contact the emergency service while preparing to go. Do not wait for improvement.
Book a vet promptly	Persistent or recurring limping; a leg the dog will not use; an eye held shut or looking cloudy; new hind-leg weakness; stumbling or paw dragging; repeated unexplained vomiting or diarrhea; unusual bleeding; a painful or growing lump	Arrange an examination. Tell the clinic what changed, when it began and whether it is worsening so staff can advise how quickly the dog should be seen.
Routine monitoring or scheduled preventive discussion	Gradual weight change; declining stamina without fainting or breathing difficulty; mild mobility changes; recurring itch or ear trouble; non-emergency changes in thirst, appetite or urination	Record the trend and discuss it at an appropriate appointment. Escalate sooner if it persists, worsens, becomes painful or is joined by an emergency sign.

Compare the dog with its own baseline. A quiet Great Pyrenees may naturally rest for long periods, so look for changes such as greater difficulty rising, less interest in normal activities or an altered response to food and family members.

When something changes, record:

• When it began
• Whether it is improving, stable or worsening
• Which limb, eye, ear or body area is involved
• Whether it is constant or intermittent
• Any change in appetite, thirst, urination or bowel movements
• Changes in energy, sleep, breathing or willingness to move
• Any recent injury, procedure, diet change or possible exposure

Short videos can help show a veterinarian an intermittent limp, skip, tremor or stumble that may not appear in the examination room. Record without forcing the dog to repeat a painful movement.

It does not mean delaying care through continued pain, repeated episodes, deterioration or an emergency pattern. Paw Primer explains that its guides stop where at-home judgment runs out and use the higher urgency category when signs overlap (about Paw Primer’s three-step approach).

Everyday care that supports health across life stages

No diet, exercise plan or supplement can guarantee prevention of dysplasia, GDV, cancer or another inherited disorder. Everyday care can nevertheless support general health, reduce avoidable strain and make changes easier to notice.

Puppy priorities

Great Pyrenees puppies need steady, controlled development rather than maximum-speed growth. Priorities include:

• Feeding an appropriate large-breed puppy diet
• Avoiding overfeeding
• Monitoring body condition as the puppy grows
• Following veterinary guidance about suitable activity
• Investigating persistent or shifting limb pain
• Avoiding calcium supplements unless a veterinarian directs their use

Veterinary breed guidance associates overly rapid growth with osteochondritis dissecans and recommends a large-breed puppy diet, avoidance of overfeeding and no extra calcium supplementation (Sutton Animal Hospital’s puppy and orthopedic guidance).

The appropriate amount of food depends on the product’s energy density and the puppy’s growth, body condition and activity. A universal number of cups or rigid exercise schedule is not suitable for every puppy.

Adult priorities

For adult Great Pyrenees, focus on sustainable habits:

• Maintain a healthy body condition
• Provide regular activity appropriate to the dog’s health and conditioning
• Attend routine veterinary examinations
• Maintain dental care
• Follow an individualized vaccination plan
• Use veterinarian-recommended parasite prevention
• Investigate recurring lameness, skin problems, ear inflammation or digestive changes

Weight management may help support joint health and limit complications associated with obesity. It cannot change inherited joint structure or promise that arthritis will never develop.

Activity should be adjusted to the individual. A healthy adult and a dog with advanced arthritis should not be expected to follow the same routine. Seek veterinary guidance when pain, heart concerns, recent surgery or orthopedic disease affects safe activity.

Senior priorities

In older dogs, trends are often more informative than one unusual day. Pay attention to:

• Gait and paw placement
• Ease of rising and lying down
• Ability to manage stairs or familiar surfaces
• Stamina on ordinary walks
• Appetite and body condition
• Thirst and urination
• Bowel habits
• Vision and navigation
• New or changing lumps
• Hind-leg strength
• Coughing, fainting or altered breathing

Do not assume every decline is unavoidable aging. Arthritis, eye disease, dental pain, hormonal illness, cancer and neurologic disease may all change behavior or function, and some causes may be manageable once identified.

Keep a simple health log

Periodically note:

• Weight or body-condition trend
• Ease of rising and walking
• Appetite
• Thirst
• Energy and stamina
• Skin or ear flare-ups
• New lumps or changes in existing ones

This log is a communication aid, not a diagnostic tool. Bring it to appointments if it reveals a trend. Dated photographs taken with a consistent reference point may also help document whether a visible lump is changing.

Seek individualized advice before changing diet, restricting exercise, starting supplements, selecting pain control or buying mobility equipment. Supportive bedding, traction and ramps may help some dogs, but the best combination depends on the dog’s size, diagnosis, home and current abilities.

Screening, diagnosis and questions for breeders or vets

Screening, diagnosis and prevention are related but distinct:

• Prevention attempts to reduce the likelihood or impact of a future problem.

Depending on the dog and clinical context, a veterinarian or breeder may discuss:

• Hip and elbow imaging
• Eye examinations
• Blood or urine testing
• Clotting evaluation
• Condition-specific DNA testing
• Imaging for current lameness or growth-related concerns

Its meaning depends on the condition and inheritance pattern. A DNA result does not necessarily diagnose active disease, predict severity or exclude inherited disorders the test did not assess.

Questions to ask a breeder

Ask for actual documentation rather than relying on a statement that the parents were “healthy” or “vet checked.”

Useful questions include:

• Can I see documented hip results for both parents?
• Can I see their elbow results?
• Have both parents had documented eye examinations?
• Which condition-specific genetic tests were performed, and can I see the reports?
• Was any relevant clotting evaluation performed?
• Is there a family history of GDV?
• Have close relatives developed significant mobility disease or required orthopedic surgery?
• Is there a family history of cataracts, entropion or other eye disorders?
• Have close relatives had osteosarcoma or another serious cancer?
• Is there known neurologic disease or progressive hind-leg weakness?
• Has Addison’s disease occurred in the family?
• At what ages did affected relatives develop signs?

These questions do not imply that every test is required or that there is an official universal panel. Documentation simply allows a prospective owner to understand what was examined and what remains uncertain.

Questions to ask your veterinarian

For a current Great Pyrenees, consider asking:

• Does the dog’s gait, history or examination justify orthopedic imaging?
• Would an eye examination be useful?
• Do current symptoms warrant blood or urine testing?
• Is clotting evaluation appropriate before a planned procedure?
• Would a condition-specific DNA result change care or breeding decisions?
• Is the dog’s body condition affecting joint health?
• What activity is appropriate for this dog?
• Should preventive gastropexy be discussed for this individual?
• Which gradual changes should prompt an earlier recheck?

The available evidence does not establish an official Great Pyrenees screening schedule, mandatory test panel or universal testing age. Decisions should reflect the dog’s family records, intended breeding status, examination findings, symptoms and veterinary advice.

They are not a lifetime health guarantee. Changes in gait, eyes, skin, ears, thirst, energy or bleeding still deserve attention even when earlier screening was normal.

Frequently asked questions

Are Great Pyrenees generally healthy dogs?

Yes. They are often described as generally or relatively healthy, but that does not mean they are free from breed-associated risks. Orthopedic, digestive and eye disorders are among the concerns reported in breed-health sources, while an individual dog may never develop them.

Good records, routine veterinary care and prompt investigation of changes can reduce uncertainty, but they cannot guarantee future health.

What are the warning signs of bloat in a Great Pyrenees?

Possible GDV signs include a swollen or tight abdomen, repeated unproductive retching, restlessness, excessive drooling, abdominal pain and a prayer-like posture.

Leave for an emergency veterinary hospital immediately. Owners cannot safely distinguish simple stomach upset from GDV by appearance alone.

Why is my Great Pyrenees limping, skipping or bunny-hopping?

These movement patterns have multiple possible causes. Hip or elbow dysplasia can cause stiffness and lameness, while patellar luxation may produce intermittent skipping. Injuries, paw problems, growth-related disorders, spinal conditions and bone pain can also alter gait.

Persistent bunny-hopping may justify examination of the hips, but it does not prove hip dysplasia. A leg the dog will not use, marked pain or rapid deterioration needs prompt attention. Limping that persists or returns should be examined.

Should every Great Pyrenees have preventive gastropexy?

No. Preventive gastropexy is an individualized option to discuss with a veterinarian, not a universal requirement for every Great Pyrenees.

Regardless of whether surgery is discussed or performed, owners still need to recognize abdominal swelling, unproductive retching and other emergency signs.

How long do Great Pyrenees usually live?

A commonly cited lifespan is approximately 10–12 years, but individual longevity varies. A breed-level range cannot predict how long a particular dog will live.

The practical priorities

A breed predisposition is not a prediction for your Great Pyrenees. The most useful approach is straightforward:

• Recognize possible GDV and act immediately.
• Arrange an examination for persistent mobility, eye, neurologic, bleeding or systemic changes.
• Maintain a healthy body condition without relying on lifestyle measures as guaranteed prevention.
• Ask for documented screening information and use veterinary guidance to make individual decisions.
• Choose the higher urgency level whenever signs overlap.

General information and symptom frameworks can help organize your response, but they cannot replace veterinary diagnosis or emergency care.
