Great Pyrenees vs Newfoundland
A side-by-side comparison to help you find the right breed for your lifestyle.
Great Pyrenees
Also known as: Pyr, Pyrenean Mountain Dog, Chien de Montagne des Pyrenees
The Great Pyrenees is a majestic livestock guardian weighing 38-72 kg, bred to work independently in the Pyrenees Mountains. While gentle with family, their nocturnal barking, roaming instinct, and independent nature require experienced owners with secure fencing. Not recommended for apartments or first-time owners.

Newfoundland
Also known as: Newf, Newfie, Gentle Giant
The Newfoundland is a giant, gentle breed renowned for its impressive strength, thick water-resistant coat, and remarkable swimming ability. Bred to haul fishing nets and pull carts in the freezing North Atlantic, they're often called 'gentle giants' and are famous as 'nanny dogs' for their patient nature with children. But be prepared: a 150lb dog with separation anxiety can destroy drywall in minutes, and the slobber reaches ceilings.

Owner Fit & Decision Guide
Owner Match
| Trait | Great Pyrenees | Newfoundland |
|---|---|---|
| Experience Level | Advanced | Beginner (temperament) but Advanced (logistics/finances) |
| First-Time Owner | ||
| Ideal Owner | Experienced owner with acreage or large securely fenced yard, tolerant of nocturnal barking, understanding of independent working breeds, possibly with livestock to guard. Patient with training and comfortable with a dog that thinks for itself. | Someone with a house and yard, works from home or flexible schedule, tolerant of slobber/hair/mess, financially prepared for giant breed costs, has or can get large vehicle for transport, and ideally has mentor or professional trainer for first-time giant breed ownership. |
Great Pyrenees Dealbreakers
- Live in an apartment or rental
- Have close neighbors sensitive to barking
- Want a dog that obeys commands instantly
- Don't have a secure physical fence
- Want a pristine, fur-free home
- Need a running or high-intensity exercise partner
Newfoundland Dealbreakers
- Tight budget - if $3,000 vet bill is a disaster
- Clean freak - cannot have pristine home with a Newfie
- Tiny living space - they take up physical floor space
- Hot climate without AC
- Unable to physically manage a 150lb dog
Surrender Risk
| Factor | Great Pyrenees | Newfoundland |
|---|---|---|
| Risk Level | High | Medium |
| Primary Reasons | Nocturnal barking - owners get a fluffy puppy that starts barking all night at 1 year old, Roaming/escape - jumping fences to expand territory, Resource guarding - growling over food scares families who expected Golden Retriever temperament, Size underestimated - 120lb dog that refuses to move and may growl when asked to get off couch | 'He got too big' - owners underestimate reality of 150lb dog in a hallway, Medical costs - giant breed vet bills are shocking to unprepared owners, Grooming/mess - drool and hair become unmanageable for some |

Great Pyrenees Social Traits
High
Same-sex aggression common, especially females. Keep opposite-sex pairs for peace.
Newfoundland Social Traits
None
Generally low - tolerant of other dogs. Same-sex aggression rare but can occur in intact males.
Training
Great Pyrenees
- Must convince them your request is worth their effort
- Harsh corrections cause shutdown or defensive behavior
- Focus on management over strict obedience
- Accept that recall will never be 100% reliable
Newfoundland
- Start training early while they're still manageable size
- Use social connection and food as motivators
- Harsh methods cause them to shut down completely
- Be consistent - a giant dog that ignores commands is dangerous
Great Pyrenees Considerations
The #1 complaint from suburban owners. Pyrs are genetically hardwired to patrol and bark at night - they were bred to ward off wolves and bears. This instinct cannot be trained out, only managed. Expect deep, booming barks at 2 AM when a leaf blows across the driveway.
Great Pyrenees do not believe in property lines. Without a secure 5-6 foot physical fence, they will expand their territory to include the entire neighborhood. They are notorious escape artists and will take the shock from invisible fences to pursue threats.
Adult Pyrs often exhibit severe aggression toward dogs of the same sex, particularly females. This usually manifests around social maturity (18-24 months). Opposite-sex pairs are generally recommended.
Pyrs are not dumb - they are independent. When called, they evaluate whether coming is more important than what they are currently doing (usually guarding). If they decide it isn't, they will ignore you completely.
Newfoundland Considerations
Newfoundlands were bred to work closely with fishermen and do not tolerate isolation well. A 150lb dog with separation anxiety can destroy drywall, doors, and furniture in minutes. They need someone home most of the time.
This is non-negotiable. Loose jowls trap saliva - when they shake their heads, 'slobber strings' reach ceilings, walls, and guests. If you're house-proud or easily grossed out, this breed is incompatible with your lifestyle.
Between 6-18 months, they're large, clumsy, and energetic with no body awareness. They accidentally injure children or elderly owners simply by bumping into them. A puppy growing 10lbs/month is logistically immense.
Everything costs 2-3x more: $100-150/month food, $100-250/month insurance, medications priced by weight. If a $3,000 vet bill is a disaster, do not get this breed.
Multi-Species Compatibility
| Species | Great Pyrenees | Newfoundland |
|---|---|---|
| With Cats | Excellent - bred to protect vulnerable animals, views cats as part of the flock to guard | High safety - one of the safest giant breeds for multi-pet homes. Drive is 'chase to play' not 'chase to kill.' |
| Small Mammals | Good - low prey drive, protective instinct toward smaller animals in their family | Generally safe, but supervise due to size difference |
| Birds / Reptiles | Good with supervision - generally safe due to arrested predatory sequence | Generally safe with livestock but may accidentally squash chickens trying to play |
Advanced Behavior
| Trait | Great Pyrenees | Newfoundland |
|---|---|---|
| Predatory Sequence Risk | Arrested | Arrested |
| Biddability | Low | High |
| Noise Sensitivity | Low | Low |
| Territorial Barking | ||
| Same-Sex Aggression Onset | 18 months | N/A |
Great Pyrenees: Predatory sequence arrested early - may chase predators to drive away but lack dissect/consume drive. Brilliant problem solvers but low 'working intelligence' (willingness to follow commands). Bred to work without humans so don't look to humans for answers.
Newfoundland: Predatory sequence arrested at Eye -> Stalk -> Chase. The 'Grab-Bite' and 'Kill-Bite' are largely inhibited - they may chase a cat but usually just want to sniff or lick it. They are 'protection by presence' dogs - more likely to hold an intruder down or block them than bite. They assess before acting ('Newfie time') rather than responding robotically.

|---|---|---|
| Puppy Difficulty | ||
| Destructive Phase | 6-18 | 6-18 |
| House Training | Medium | Easy |
| Crate Training | Medium | Medium |
| Adolescent Regression |
Great Pyrenees: Pyr puppies are large, stubborn land sharks. A 6-month-old is the size of a German Shepherd but has the brain of a toddler. Critical socialization window 8-16 weeks - must expose to strangers, other dogs, and strange noises or natural guarding instinct can turn into fear-aggression.
Newfoundland: Temperamentally sweet but logistically immense. Puppy grows 10lbs/month. 'Land shark' biting on a giant breed HURTS. Joint protection is demanding - no stairs, no jumping until 2 years. Must solidify leash manners before they reach 50lbs.

Senior Care & Aging
Great Pyrenees Senior Care
Common Senior Issues
- Arthritis/mobility decline
- Osteosarcoma (bone cancer)
- Hip dysplasia progression
- Vision decline
Mobility slows around 8+ years. Arthritis management becomes primary focus. Ramps for cars and stairs become necessary.
Newfoundland Senior Care
Common Senior Issues
- Hind-end weakness (mobility issues)
- Heart disease
- Arthritis
Decline can be rapid. Be prepared to assist a 150lb dog who cannot stand up - harnesses and ramps become daily tools. Quality of life decisions are complex due to physical impossibility of managing an immobile giant dog.
