The Landseer is a dog breed. The breed is not recognized by all kennel clubs. It is not to be confused with a white and black Newfoundland, which is also often called a 'landseer'. The Landseer Newfoundland dog is known for its sweet disposition, gentleness, and serenity. They enjoy swimming and tend to drool, though not as much as some other giant breeds. During colonial times, large white and black 'Newfoundland dogs' were brought to England. Because of their good swimming skills, these dogs were used by fishermen to tow nets to the shore. They were also noted for their ability to help drowning people; therefore, these dogs were bought and sold mainly by European fishermen. It is believed that, by and large, the exportation of these dogs occurred during the late 18th century. However, paintings show us that these dogs must have already existed in England in the early 18th century.
