Tosa vs American Eskimo Dog - Breed Comparison | MyDogBreeds

Known also as the Japanese Mastiff, the Tosa hails from Japan. In fact, these dogs come from the Tosa Province, so the dog was named after the region where they were bred.

It is why they are sometimes referred to as Japanese Mastiffs. The Tosa is a rare dog breed and unfortunately, the dog is still used in Japan for dogfighting.

Thought to be a dangerous dog breed, it is restricted in some countries.

The breed was developed in the 2nd half of the 19th century, with a number of dog breeds being involved to bring about a more powerful, braver dog.

The American Eskimo is derived from the Nordic Spitz breed and most closely related to the German Spitz in particular. There were many German Spitzes in the United States at the time of the second World War and anti-German sentiment caused its name to change to the American Eskimo Dog. However, as the breed developed over time in the States, the American Eskimo became its own separate breed. In addition to the German Spitz, the American Eskimo is also related to the white Keeshond, the Samoyed, the white Italian Spitz and the white Pomeranian. The history is beginning to show that the Spitzes that were brought to the US in the early 1900’s was white. This color was not popular in Europe but was quickly the favorite in the United States. They were originally working dogs on farms and ranches. They have excellent herding instincts, make goo watch and guard dogs, and good law enforcement sniff dogs. However, their first introduction to the American public was through the Cooper Brothers’ Railroad Circus and Stout’s Pal Pierre at the Barnum and Baily Circus. Eskimo puppies were sold after the circus show.

It was then that the breed became one of America’s favorite breeds and they quickly became house pets. Following World War II, Japan exported the Japanese Spitz into America and it was crossed with the Eskimo also. The American Eskimo Dog breed was not recognized by AKC until 1985. Still in 1958 there was no official breed club in the States but there were growing numbers of the dogs. It was not until 1970 did the National American Eskimo Dog Association (NAEDA) come into being. They collected the pedigrees of the first 1750 dogs to be AKC registered.
