Newfoundland vs Old English Sheepdog
A side-by-side comparison to help you find the right breed for your lifestyle.
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.

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.
Old English Sheepdog Considerations
This is a "Velcro" breed in the truest sense. They were bred to work closely with shepherds and drovers, never straying far. In a modern home, this translates to a dog that may panic when left alone. Destructive chewing, howling, and house soiling are common symptoms of distress if isolation training is not started immediately in puppyhood.
The OES has a unique, ringing bark often described as "two pots clanging together." It is loud, deep, and can become a nuisance. They are alert watchdogs and will vocalize at delivery trucks, neighbors, and squirrels. This makes them poor candidates for apartments with noise restrictions.
As a drover's dog, the OES controls movement. In a family setting, this often manifests as nipping at the heels of running children or "body checking" people to move them. While not aggressive, this behavior can be frightening for toddlers and annoying for guests.
While generally social, some OES lines—particularly males—can develop aggression toward other dogs of the same sex around social maturity (18-24 months). This requires vigilant management in multi-dog households.
Multi-Species Compatibility
| Species | Newfoundland | Old English Sheepdog |
|---|---|---|
| With Cats | High safety - one of the safest giant breeds for multi-pet homes. Drive is 'chase to play' not 'chase to kill.' | Generally safe with proper introduction |
| Small Mammals | Generally safe, but supervise due to size difference | Supervision required |
| Birds / Reptiles | Generally safe with livestock but may accidentally squash chickens trying to play | Caution advised |
Advanced Behavior
| Trait | Newfoundland | Old English Sheepdog |
|---|---|---|
| Predatory Sequence Risk | Arrested | Medium |
| Biddability | High | Low |
| Noise Sensitivity | Low | Low |
| Territorial Barking | ||
| Same-Sex Aggression Onset | N/A | 18 months |
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.

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.
Old English Sheepdog: Old English Sheepdog puppies require consistent training and patience.
