Characteristics, History, and Health


The exact origin of the Newfoundland, or Newfie, is unclear, but they are named after Newfoundland island off the east coast of Canada. It is there that they were likely developed from a mix of indigenous dogs and those introduced by the island's settlers, such as the Portuguese, Basques, and perhaps the Vikings. One assumptoin is that the Tibetan Mastiff was introduced and bred with island dogs. The Newfie was bred as a working dog to carry things, rescue swimmers, and tow lines of ships to land. At one point in time, Newfies were required at lifeguarding stations because they were so accomplished at saving people from drowning. They have partially webbed feet, a feature that contributes to their capacity as a successful swimmer. They are also intelligent in their rescuing technique, in that if the person is conscious, they allow them to hold on while being brought to safety; if the person is unconscious, the Newfie will grab the person by the arm so they float on their back while being pulled to safety. They also worked on land pulling loads like lumber, food, or delivering mail long distances.

Genetic Predispositions and Health

Newfoundlands can suffer from elbow and hip dysplasia, cystinuria, gastric torsion, epilepsy, subaortic stenosis, von Willebrand disease, cruciate ligament rupture, osteochondritis dissecans, degenerative myelopathy, and thrombopathia. They may also be prone to eye disorders including entropion, ectropion, and cataracts. Newfoundlands have a heavy coat and do not tolerate heat well. Some are very sensitive to anesthesia, so it is important to discuss before any planned surgery. As for all breeds, genetic screening is recommended to assist veterinarians with diagnosis and proactive care, as well as help breeders identify affected and carrier dogs.

Personality and Behavior

Newfoundlands are known for their gentle, sweet-natured temperament. They are usually very good with children and get along well with other animals. They are intelligent, trainable, and protective, but not aggressive. Their calm and patient nature, coupled with their love of water and innate swimming ability, has earned them the nickname "gentle giants".

Newfies have a heavy coat and do not do well in warm weather. They also have an abundance of energy and should be taken on regular walks or given regular activity. They are easily trained and enjoy working with humans. Newfies are also protective and will place themselves between their family and intruders, they are only aggressive when they feel their family or owners are threatened.
