Tornjaks are large, beautiful dogs with long hair in different colors; they are dogs with protective instinct, exceptionally gentle and careful with children. Like all other shepherd dogs they are devoted to their family (their human pack), distrusful and reserved towards unfamiliar.

Where do these nice and smart dogs come from, you'll ask me? A canon from Đakovo who was the manager of the bishop's estate in Đakovo, Petar Lukić, wrote in his reports from 1752. about a Croatian mountain dog 4 to 5 palms tall (60 to 75 cm), with different colors that could be black, grey, yellow, brown and red or combined with white. Some even have three colors.

The ears hang down and the tail is cover with thick hair. The Tornjak is mainly used for defending livestock, but also people from wild beasts, particularly wolves.

This dog is mostly bred in the mountain parts of Croatia, which is the reason why they are sometimes called "Canis montanis", or mountain dog.
