Newfoundland Health Problems: Symptoms and When to Worry
The most common Newfoundland health problems are subvalvular aortic stenosis, hip dysplasia, and bloat. Newfoundlands typically live 8–10 years. This page is organized by symptom, so you can jump straight to heart, joint, digestive, and kidney problems, see what each one looks like in a Newfoundland, and know whether it is a vet visit this week, a vet visit today, or an emergency right now.
Quick answer: when to worry about your Newfoundland
Go to an emergency vet now if you see any of these:
- Heart: Collapse, fainting, blue gums, labored breathing, or sudden hind-leg paralysis with cold legs (a clot) is an emergency.
- Joint, back, and mobility: Sudden inability to use the back legs, dragging the hindquarters, or crying out when touched along the spine is an emergency. A ruptured disc has a window of hours for the best outcome.
- Stomach and digestive: Retching that produces nothing, a swollen tight belly, and restlessness are the signs of bloat, a true emergency. Blood in vomit, black tarry stools, or a pet that has stopped eating and passing droppings altogether also needs a vet now.
- Kidney and urinary: Straining to urinate with little or nothing coming out, especially in a male, is an emergency. A blocked bladder can be fatal within a day or two.
- Any pet: collapse, seizures lasting more than five minutes, uncontrolled bleeding, or an inability to stand.
Book a vet visit this week if you see any of these:
- Heart: A murmur your vet has heard, coughing at night, tiring on walks, or a resting breathing rate over 30 breaths per minute while asleep.
- Joint, back, and mobility: Limping for more than a day or two, stiffness after rest, reluctance to jump or climb stairs, or a change in gait.
- Stomach and digestive: Vomiting or diarrhea lasting more than 24 hours, refusing food for more than a day, or unexplained weight loss.
- Kidney and urinary: Drinking and urinating more than usual, weight loss, a poor coat, blood in the urine, or reduced appetite.
Keep watching if: the change is mild, your Newfoundland is still eating, drinking, and moving normally, and it resolves within a day or two. Write down what you saw and when; a dated list is the most useful thing you can bring to a vet.
Heart problems in Newfoundlands
Subvalvular Aortic Stenosis (SAS)
Congenital heart defect. Common in Newfoundlands.
What it looks like in a Newfoundland:
- Exercise intolerance
- Fainting
- Sudden death
Outlook: this is one of the conditions that can shorten a Newfoundland's life. Managed early it is often years, not months, but it belongs on the list of things that eventually lead to end-of-life decisions.
When to see a vet: A murmur your vet has heard, coughing at night, tiring on walks, or a resting breathing rate over 30 breaths per minute while asleep.
When it is an emergency: Collapse, fainting, blue gums, labored breathing, or sudden hind-leg paralysis with cold legs (a clot) is an emergency.
Joint, back, and mobility problems in Newfoundlands
Hip Dysplasia
Very common in giant breeds.
How common in Newfoundlands: Affects approximately 25% of Newfoundlands
What it looks like in a Newfoundland:
- Hind leg lameness
- Difficulty rising
When to see a vet: Limping for more than a day or two, stiffness after rest, reluctance to jump or climb stairs, or a change in gait.
When it is an emergency: Sudden inability to use the back legs, dragging the hindquarters, or crying out when touched along the spine is an emergency. A ruptured disc has a window of hours for the best outcome.
Stomach and digestive problems in Newfoundlands
Bloat (GDV)
Giant breeds at high risk.
What it looks like in a Newfoundland:
- Distended abdomen
- Retching
- Collapse
Outlook: this is one of the conditions that can shorten a Newfoundland's life. Managed early it is often years, not months, but it belongs on the list of things that eventually lead to end-of-life decisions.
When to see a vet: Vomiting or diarrhea lasting more than 24 hours, refusing food for more than a day, or unexplained weight loss.
When it is an emergency: Retching that produces nothing, a swollen tight belly, and restlessness are the signs of bloat, a true emergency. Blood in vomit, black tarry stools, or a pet that has stopped eating and passing droppings altogether also needs a vet now.
Kidney and urinary problems in Newfoundlands
Cystinuria
Genetic condition causing bladder stones. Common in Newfies.
What it looks like in a Newfoundland:
- Straining to urinate
- Blood in urine
When to see a vet: Drinking and urinating more than usual, weight loss, a poor coat, blood in the urine, or reduced appetite.
When it is an emergency: Straining to urinate with little or nothing coming out, especially in a male, is an emergency. A blocked bladder can be fatal within a day or two.
Warning signs to watch for in a Newfoundland
These are the early signals owners most often miss, or dismiss as age:
- Any heart symptoms
- Bloat signs
- Mobility problems
- Exercise intolerance
Newfoundland lifespan: what is normal
Newfies typically live only 8-10 years. If yours reached 10+, that's a blessing. Giant breeds don't live long.
Genetic factors
Size creates health burden. Heart disease, hip dysplasia, and bloat are major concerns.
What Newfoundlands usually die from
Knowing what typically ends a Newfoundland's life is not morbid. It tells you which of the symptoms above deserve the fastest response.
- Heart disease (about 25%): Including SAS.
- Cancer (about 25%): Various cancers.
- Bloat (about 15%): Emergency condition.
- Age-related decline (about 20%): Organ failure - though 'old age' comes young.
When it may be time: from managing symptoms to saying goodbye
Some of the conditions above (subvalvular aortic stenosis and bloat) are managed for years. Each one, though, has a point where treatment prolongs the decline rather than the life. If you are reading this page because your Newfoundland is older and the bad days are starting to outnumber the good, that is worth saying plainly: you may not be looking for a diagnosis anymore. You may be looking for permission.
Signs the balance has shifted in a Newfoundland:
- Unable to stand or walk
- Breathing difficulty
- Loss of that gentle spirit
- Unable to swim anymore

If you are weighing costs and options, the pet end-of-life services guides by city cover in-home euthanasia and cremation prices, and the coping with losing a Newfoundland guide is there for afterward.
Preventive care for Newfoundlands
- Cardiac screening essential
- Hip screening
- Know bloat signs
- Maintain lean weight
- Joint support

If this has stopped being about symptoms
Many people land here when their Newfoundland is old or ill and they are trying to work out whether what they are seeing is the end. If that is you, the health details above matter less than the question underneath them.
