Overview
The Tornjak is a large livestock guardian from the mountains of Bosnia and Herzegovina and Croatia, bred to protect flocks from wolves and bears. Powerful and weatherproof, it works with calm, steady, independent vigilance.
Devoted, calm, and protective, the Tornjak bonds deeply with its family and flock while remaining dignified and wary of strangers. Bred to work with little direction, it is a serious guardian needing space and experienced ownership.
History
An ancient Balkan breed documented for centuries, the Tornjak guarded sheep and cattle in the mountains of Bosnia and Croatia. Nearly lost in the 20th century, it was revived through dedicated preservation efforts.

Temperament
The Tornjak is steady, loyal, and vigilant, gentle with family and charges yet wary of outsiders. It is highly independent, bred to decide for itself, needing early socialization and calm, confident, consistent handling.
Health to watch
Joint malformation occurs in large breeds; screening and lean weight help protect the joints over time.
The deep chest raises the risk of gastric torsion; smaller meals and rest around eating are wise.
As a landrace working breed, the Tornjak tends to be robust with relatively few inherited disorders.
General breed tendencies, not a diagnosis. Every dog is an individual — pair this with regular veterinary care.
Care essentials
This guardian needs room to patrol and secure fencing; it is unsuited to small or busy homes.
Early, broad exposure keeps the breed's strong guarding instincts balanced and reliable.
The long, thick double coat needs regular brushing and sheds heavily during seasonal changes.
