In temperament the breed is alert, lively and intelligent, closely attached to its handler and often reserved with strangers. It is a watchful, vocal dog that readily raises the alarm, a trait valued on the farms where it was developed.
It is a lightly built, agile dog, slightly longer than tall, with a wedge-shaped head and pricked or semi-pricked ears. The coat is black, soft and wavy to curly over the body, but short and smooth on the face and the front of the legs, which gives the dog a distinctive tidy-faced look. Small white marks on the chest or toes are tolerated. Some puppies are born with naturally short tails.
The Croatian Sheepdog, known at home as the hrvatski ovčar, owes its present form largely to the work done in the mid-twentieth century to fix a consistent type from the farm dogs of Slavonia. The breed was later accepted by the Fédération Cynologique Internationale, with Croatia as its country of origin. It was bred as a working herder of sheep and cattle, moving stock quickly and nimbly on the flat lands of eastern Croatia, and it is still used on farms there. Outside its homeland it remains uncommon.
