Newfoundland dogs are a beloved breed, known for their massive size and gentle nature.

On average, male Newfoundlands weigh between 130-150 pounds and stand between 28-30 inches tall at the shoulder.

Their large size requires plenty of space to move around, which is why they're not suited for small living spaces.

Newfoundlands need regular exercise to stay healthy and happy.

Their weight gain is a significant factor in their growth, with puppies gaining up to 3 pounds per week during their first year.

As they grow, they'll need a balanced diet to support their development.

The Newfoundland breed has a rich history that dates back to its origins as a working dog for fishermen in Newfoundland. The breed's connection to other dogs, such as the Irish water spaniel and Curly-Coated Retriever, is evident in genome analysis.

Originally, the Newfoundland was bred and used by fishermen and explorers from Ireland and England who traveled to the Grand Banks of Newfoundland. They described two main types of working dogs, one being the heavily built Greater Newfoundland and the other the medium-sized St. John's water dog.

The Greater Newfoundland was known for its large size and longish coat, while the St. John's water dog was active and smooth-coated. Both breeds were used as working dogs to pull fishnets, with the Greater Newfoundland also being used to haul carts and other equipment.

It's believed that the original Newfoundland on the island was smaller, and when sold to the English, it was bred with mastiffs, resulting in the larger breed we know today.

Today, they've earned a gentle reputation as "nanny dogs" that get along well with children.

Newfoundland dogs can be prone to obesity if they have a sedentary lifestyle, so it's essential to pay attention to their diet.

Choosing the right food for your Newfie is crucial, and that means selecting a brand specially formulated for giant breeds that is high in protein, low in carbohydrates, and doesn't include fillers or preservatives.

Free-feeding your Newfoundland is not recommended, as it can be difficult to track how much they eat, and this can lead to overeating and weight gain.

Puppies need to be fed at least four times a day, while adult Newfoundlands can be fed two to three times a day, depending on their individual needs and activity level.
