This design first appears in the 1850s coming out of Hayward Barlett and Company of Baltimore. After its original appearance, variations of this dog were made or copied by many companies . This identical statue is in the 1858 Robert Wood & Company catalogue as no. G. This evidence points to Robert Wood and Company as making the Belmont dog and it being purchased before the Civil War. A review of the 1870 catalogue reveals a slight change to the design of the dog’s tail . In the 1870 catalog, “G” page 297, this statue is shown in two sizes 3’9” and 5’5” .
Dogs were the most popular domestic pets in the Victorian era and the Newfoundland was the most beloved. The British artist Sir. Edwin Landseer is best known for his romanticized images of Newfoundlands in paintings and prints. Most often, the dog is portrayed in service to humankind as a sign of its noble character.
