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.
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.
Teddy Roosevelt Terriers (Teddy, American Teddy) are American hunting terriers related to American Rat Terriers and a host of other working, farm, hunting dogs initially brought by working-class immigrants from England and Europe. Largely due to the working nature of these dogs early the cross breeding was to reinforce useful traits like a superior ability to scent prey. It also bequeathed the breed with superior intelligence. While they take a while to warm up to new people, to their human family they like to be close all the time, and are eager to be with them and please them. Teddy's share their early history with American Rat Terriers, Fox Paulistinha, Tenterfield Terrier and Beagles. They also are related to Feist (dog), and Turnspit dogs, English White Terrier and Wry-legged terrier (all now extinct), as well as Bull, Smooth Fox, Manchester Terriers with Beagles, Italian Greyhound and Whippets in the mix.
Only since 1996 have Teddy Roosevelt Terriers had standards set for the breed. The major difference between Teddys and the related American Rat Terrier is Teddys are closer to the ground (bench-legged), have greater bone density and more muscle. Teddys are medium to small sized. It was in the mid 1990's that the effort began to breed only the shorter legged phenotype into the Teddy lineage and allow the rat Terrier to be the longer legged variety. The UKC (United Kennel Club) and AKC (American Kennel Club) both recognize Teddys, the UKC since 1999.
The Rat Terrier Club of America separated the long legged and short legged varieties, the short legged ones were named in honor of President Theodore Roosevelt. It is rather interesting that President Theodore Roosevelt, while being very fond of his family dogs did not own any Rat Terriers, and did not help develop the breed that bears his name. He mentions dogs in several of his letters, Skip who rode with the president on his horse while hunting and belonged to a friend, Scamp who lived with the Roosevelt's in the White House and hunted and caught rats and their dog Jack.
