Tosa vs American Water Spaniel - Breed Comparison

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 Water Spaniel was developed in the United States. He is the state dog of Wisconsin and was developed there in the 19th century. The bloodlines of this spaniel are varied but certainly include the English Water Spaniel and the Irish Water Spaniel. Even though they are the state dog of Wisconsin they were almost extinct when Dr. Fred J. Pfeifer rescued the breed. The numbers had fallen after World War II because hunting was now a recreational sport and not needed to provide food for the family. He then started a breed club and wrote a breed standard, both of which were recognized by the United Kennel Club and the American Kennel Club. When first developed the American Water Spaniel was known as the American Brown Spaniel. It was bred with a curly, thick coat so that it cold be sustained in Wisconsin winters and cold water. It was bred to hunt grouse, water fowl and prairie chickens as well as furry land animals. Pfeifer advertised his dogs for sale everywhere using a mailer that read: “, "The American Brown Spaniel is distinctively an American production. Hunters have known this type for years and it was through their efforts that this dog was propagated.... For years we have bred only selective stock, breeding for gameness, stability, courage, intelligence, and beauty. They are dogs to admire and trust under all conditions whether in the home circle or in the field with the outdoor man."[2]

In Wisconsin, around the wolf River and the Fox River, hunters were looking for a water dog that could also hunt on land. They needed a dog that could work a variety of fowl and game but who was small enough for a skiff and strong enough for the artic water temperatures of Wisconsin in the Winter. So, in addition to the spaniels named above, other breeds such as the Curly Coated Retriever, the Poodle, Native Indian dogs and the Sussex Spaniel were intermixed. When first developed the American Water Spaniel was known as the American Brown Spaniel. It was bred with a curly, thick coat so that it cold be sustained in Wisconsin winters and cold water. It was bred to hunt grouse, water fowl and prairie chickens as well as furry land animals. The American Water Spaniel was then itself used to develop another new breed, the Boykin Spaniel. In 1985 Wisconsin declared the American Water Spaniel to be the official state dog. Even so there remain only a few thousand dogs in existence. Though recognized by the AKC, they are neither spaniels nor retrievers and remain unclassified. Because of this they cannot compete in AKC field trials, but they do compete in AKC hunt tests. Though rare, the American Water Spaniel is a great hunting dog, retriever and companion.
