Temperament & Personality
Tosa Inu is a fearless, peaceful and quiet natured dog, it is very loyal and devoted to its family. This breed is not ideal for the first time dog owners and requires an authoritative master. Otherwise, the dog might get aggressive to humans, pets and other animals. However, they are the best playmates for children. Proper training can develop general etiquette and gentle behavior. They do not mix well with unknown people and take a minimum of four years to grow completely. Dogs of the same size, temperament and sex should not be kept together as they are fighting dogs and can end up fighting and injuring the other pet. They tend to do things in their way as they are very stubborn and independent-minded.
