The short answer
Have a Newfoundland’s heart checked carefully, with an echocardiogram for any murmur. Keep the dog lean and see a vet for sudden hind-leg lameness. Watch for straining to urinate, especially in males. Learn the signs of bloat, and keep a Newfie cool in summer. Price pet insurance in your first week.
The heart
Subaortic stenosis is an inherited narrowing below the aortic valve, and a cardiology practice handout lists the Newfoundland first among the breeds where it is most often found. Severe cases can cause fainting or sudden death in young dogs. The first clue is usually a murmur, which deserves an echocardiogram with a veterinary cardiologist.
Newfoundlands are also among the breeds Cornell names for dilated cardiomyopathy, a weakening of the heart muscle in adults. Tiring easily, coughing, fast breathing at rest or fainting need prompt attention.

Ask the rescue whether the dog has had heart screening or a cystinuria DNA test.
See Available Newfoundlands →Knees and hips
A study of cruciate ligament rupture in young dogs found a breed predisposition in Newfoundlands. Sudden lameness in a back leg after play is the typical sign. Hip and elbow dysplasia are also common in heavy giant breeds; VCA stresses lean growth, a large-breed growth diet and low-impact exercise. Swimming is ideal exercise for most Newfies.
Cystinuria
Cystinuria is an inherited condition that lets an amino acid called cystine form bladder stones. Researchers identified the mutation responsible in Newfoundlands and developed a DNA test, and the Merck Veterinary Manual notes that most cystine stones are found in younger, intact males.
Straining, frequent small amounts or blood in the urine need a vet, and a male that strains and passes nothing is an emergency. Ask the rescue whether a DNA test has been done.
Bloat and heat
As a giant, deep-chested breed, a Newfoundland should be watched for bloat (gastric dilatation-volvulus). Unproductive retching, a swollen belly, drooling and restlessness need emergency care within minutes to hours, according to VCA. Ask about a preventive gastropexy.
The thick double coat is built for cold water, not summer heat. Give shade, water and cool-hour exercise, and never shave the coat.
The first vet visit after adoption
Ask for a careful heart listen and an echocardiogram referral for any murmur, a joint and knee assessment, a urinalysis, a body condition score with a written target weight and baseline bloodwork. Raise gastropexy if the dog is not yet spayed or neutered. Bring the rescue’s records.
Price pet insurance the same week. Every Canadian provider excludes conditions documented before enrolment, and cardiac, orthopaedic and bloat surgery are large costs in a giant breed.
Frequently asked questions
What are the most common Newfoundland health issues?
Subaortic stenosis, dilated cardiomyopathy, cruciate ligament tears, hip and elbow dysplasia, cystinuria, bloat and heat stress.
Should my Newfoundland have heart screening?
Yes. Newfoundlands are the breed most often listed for subaortic stenosis and are also predisposed to dilated cardiomyopathy. Any murmur deserves an echocardiogram.
What is cystinuria in Newfoundlands?
An inherited condition that lets cystine form bladder stones, most often in young, intact males. A DNA test identifies affected dogs.
Can Newfoundlands handle summer heat?
Poorly. Give shade and water, exercise in the cool part of the day, and never shave the coat.
How do I protect my Newfoundland’s joints?
Keep the dog lean, let puppies grow slowly on a large-breed diet, and favour swimming and steady walks over jumping and sudden turns.
Should I get pet insurance for a rescue Newfoundland?
It is worth pricing in your first week. Canadian pet insurance excludes conditions documented before enrolment, and heart and joint care in a giant breed are expensive.
