Croatian Sheepdog

Dog

The Croatian Sheepdog is a dog breed from Croatia.

According to written documents, the appearance of this breed has not changed greatly from the 14th century to the present day. Probably because it possesses an excellent hereditary instinct for working sheep and cattle, selection on the basis of usability was being carried out spontaneously, which has resulted also in the balance of its look.
