The Brittany is ideal for: Active outdoor families, hunters, dog sport enthusiasts, runners, those wanting a versatile sporting dog. This breed thrives when matched with the right lifestyle and owner experience level.

Not ideal for: Sedentary owners, apartment living, those wanting a guard dog, first-time owners without exercise commitment. Carefully consider whether this breed matches your lifestyle before committing.


Newfoundlands are massive working dogs from the Canadian island of the same name, originally bred to haul fishing nets, pull carts, and rescue drowning sailors. Adults typically weigh 100-150 lbs (females) to 130-180 lbs (males). They are known for their extraordinarily gentle temperament -- calm, patient, and nurturing even with small children, earning the nickname "nanny dog" -- and for their natural swimming ability, facilitated by webbed feet and a water-resistant double coat. Their health profile is dominated by cardiac disease, hip/elbow dysplasia, bloat risk, and a short lifespan of 8-10 years. Prospective owners need to understand these trade-offs before committing to a dog of this size and needs.

Subaortic Stenosis: The Cardiac Priority in Newfs

Subaortic stenosis (SAS) is the most significant heritable disease in Newfoundlands. It is a congenital narrowing just below the aortic valve that forces the heart to work harder to pump blood through the constriction. Mild SAS may cause few problems; severe SAS leads to sudden cardiac death, often in young dogs (1-3 years) before owners realize there is a problem. The prevalence in Newfoundlands is estimated at 10-25% of the breed, making it one of the most affected breeds for any single cardiac condition.

Detection: a veterinary cardiologist (board-certified) can grade a heart murmur and perform echocardiography to diagnose SAS and assess severity. The Orthopedic Foundation for Animals' Cardiac Database lists breeding dogs with cardiac clearances. Responsible Newfoundland breeders have all breeding dogs certified by a cardiologist annually; buyers should request copies of current clearances. A murmur detected at a routine vet exam requires cardiologist referral for proper grading before assuming it is clinically insignificant.

Severe SAS: restricted activity, possible medication (atenolol to reduce heart rate and cardiac workload), and vigilance for collapse or fainting. Prognosis for severe SAS is poor -- most severely affected dogs die before age 5.

Hip and Elbow Dysplasia

Like all giant breeds, Newfoundlands have significant prevalence of both hip and elbow dysplasia. OFA data show approximately 24% of evaluated Newfoundlands have hip dysplasia. Breeding dogs should have current OFA hip and elbow certifications. Management in affected dogs: lifelong weight control (critical -- every extra pound increases joint load substantially in a dog this heavy), appropriate low-impact exercise (swimming is ideal -- this is literally what they were bred for), anti-inflammatory medications (NSAIDs), and joint supplements. Total hip replacement is available for severe cases in dogs with otherwise good health.

Gastric Dilatation-Volvulus Risk

As a deep-chested giant breed, Newfoundlands carry elevated GDV (bloat) risk. Emergency signs: unproductive retching, distended abdomen, restlessness, rapid deterioration. This is a true emergency -- transport immediately to an emergency veterinary hospital. Prophylactic gastropexy (surgical stomach anchoring) can be performed at the time of spay/neuter and is strongly recommended for giant breeds with documented GDV risk. Discuss with your veterinarian before neutering.

Coat Care: A Significant Commitment

The Newfoundland coat is a dense double coat that repels water and insulates against cold -- perfectly engineered for hauling nets off Newfoundland. In a house, it requires brushing 2-3 times weekly minimum, daily during shedding seasons (spring and fall). Mats form easily behind the ears, in the armpits, and at the rear haunches. Professional grooming every 8-12 weeks helps manage coat volume. They shed year-round in substantial quantity. Plan for regular vacuuming and accept dog hair as part of the decor.

Newfs drool, especially after eating and drinking. Keep towels accessible. Some individuals drool more than others -- ask the breeder about the drool tendency in the specific litter's parents. Skin fold dermatitis can develop around the lips where drool accumulates; wipe the lip folds weekly.

Exercise and Heat

Despite their size, adult Newfoundlands need only moderate exercise: 30-60 minutes daily. The best exercise for them is swimming -- they have webbed feet, a naturally buoyant body, and a coat designed for it. Many Newfoundland owners join water rescue clubs or take their dogs to swimming facilities. On land, avoid high-impact exercise (running on hard surfaces) that stresses joints. They are extremely heat-sensitive -- their dense coat that protects against North Atlantic cold is a liability at summer temperatures. Exercise only in cool weather or early morning/evening during summer. Any rectal temperature above 104 degrees F is a heatstroke emergency.
