History of the Newfoundland

History of the Newfoundland

Newfoundland sounds like a place more than a dog when you first hear the noun. The answer is simple; it is from Newfoundland. The absurd naming convention aside, this dog has a very long history of being the undisputed dog in the water.

Newfoundlands were dogs that sailed beside sailors on the high seas. Helping any members who fell aboard the ship. The extremely large size of this dog did not hinder its rescue missions. They could easily pull up any drowning a fully grown man from underwater and go back in immediately to help any other member. 

They have trekked across the American continent with Lewis and Clark for over 8000 miles and awed the world over. These dogs have also saved others from wild animals when out comping and settling in the wilderness.

This dog breed was soo beloved there is a monument erected by Lord Byron for his dog Boatswain. He loved the dog so much that his own tomb was smaller than his dog’s tomb. This can tell you how virtuous this dog is and its merits. 

Even if this dog’s popularity has waned recently, it has steeled itself in the animal’s hall of fame for humanity.  

Newfoundland temperament and personality

Newfoundland temperament and personality

Newfoundlands are very mellow creatures with bright personalities. They have perfectly balanced personalities, the epitome of kindness and courage incarnate. 

They are hunting dogs and can hunt but don’t terrorize smaller animals. They behave really well and mind their business most times. They are matched well with the elderly and the quiet types of people. 

They are great for families but need a very large apartment to live in or a full-on yard. They don’t have as much separation anxiety as other dogs, but it is still present. 

Newfoundland physical traits

Newfoundlands are known for their physique; they are waterborne dogs. There is no other way to explain their innate ability; they are genetically evolved to their state. This gives them such huge leverage over any other dogs. 

Their paws have a semi webbed structure, helping them to maneuver in water flexibly. Their water-resistant coats do wonders for them. 


Newfound lands can weigh up to 120 to 150 pounds. And their height can be as long as 28 inches long. This shows how much of a unit this dog is. 

And they can live up to 10 years, making them a very short-lived dog breed among the other breeds.

Facial features

This dog has large and has the width of a melon; almost the ears are triangular shapes with blunt tips. The eyes are usually dark brown, spaced apart, and have brows that are a bit thicker. 

They have a proper bite, with no excess overbite or underbite. The muzzles are broad and rounded. 


They have a water-resistant coat that has flat hair follicles. They are quite thick and dry really well. They might have a wavy or straight outer coat that is not too thick or short. But the undercoat is small, dense, soft, and smooth to the touch. 

They can come in white, black, gray, brown, and a rare bronze color that is often in small light patches. 


These dogs need thorough brushing with pin brushes and combs every two days or so. They need to be bathed once or twice a month, depending on how much interaction with water they have. 

Everything else is just normal grooming for them. 


They have common health issues like luxating patellas, hip dysplasia, cataracts, and cancer, among many other diseases.

Newfoundlands are well known for their giant size and charming personality. These working dogs were bred initially as water rescue dogs. 

Newfies were the Saint Bernards of the water, and they saved many men from drowning in the icy waters of the North Atlantic during World War II. 

When you get a Newfoundland puppy as a pet, it’s natural to wonder how big this breed gets and when they will stop growing? 

We’ve created an easy-to-use growth chart that estimates your pup’s weight at each stage in their development.

The above numbers in our Newfoundland weight chart are estimates, and your puppy may grow at a different pace than what’s shown.

As giant dogs, Newfoundlands take longer than most other breeds to reach their full size. If your pup is significantly behind or ahead of the above numbers (which can happen), consult with a veterinarian about whether they’re growing appropriately for how big they’ll be when fully grown-not just tall but also wide!
