Overview
Tosa Kens are not for the faint of heart. As a blend of Mastiff, Great Dane, Shikoku, and Bulldog, these giant dogs are known to be aggressive and territorial. They make wonderful guard dogs, but they need a strong and patient owner to keep them in line.
Tosa Kens are a giant mixed breed with Mastiff, Great Dane, Shikoku, and Bulldog in their blood. These beasts can be up to 200 pounds, and they have no problem throwing their weight around. Tosas were bred as fighting dogs, so they have an inherent drive to attack. Their hostility lends well to being kept as guard dogs, but they can be dangerous around other dogs and people. Tosas are powerful and fearless, and they need a strong owner to keep them under control. If you have the patience for training and socialization, these pups will be loyal protectors.
Temperament and Behavior
Because of their fighting background, Tosa Kens are known to be aggressive around other dogs. Their hostile personality makes them great guard dogs but can be difficult to deal with day to day. However, around their families and most people they know and are comfortable with, the Tosa is usually quiet, gentle, and loyal. These dogs are smart and easy to train, especially if they’re being taught how to protect their owners.
Coat & Grooming
Tosas have short fur that comes in a variety of colors, including red, apricot, fawn, black, brindle, and tan. They’re very easy to groom, although it may take some time because of their size. Brush these pups once a week, and give them a bath every few months to keep their coat looking its best.
Lifestyle & Living Conditions
Because of their large stature, Tosa Kens are best suited for homes that have a yard and a high, solid fence. Although they seem big and tough, they actually prefer to live inside with the family. Tosas can get along with children if they’re raised together, but they’re not the best breed for families. They’re also known to be aggressive toward dogs and other animals, so they’ll be happiest in a home where they’re the only pet.
Exercise & Activity
For being such a large breed, the Tosa Ken doesn’t have as much energy as you would expect. They enjoy a daily walk or run and make great jogging companions, but 30 minutes to an hour is plenty to keep them happy and fit. Be sure to keep them on a leash or confined, though, as they may lunge at other dogs they see along the way.
