The Croatian sheepdog is of low to medium height and the base color is always black, although there may be very small patches of white on its chest and/or toes.

Traditionally the tail is docked very short but, if undocked, it is carried curled over the dog's back.

[2] The Croatian Sheepdog probably originates from dogs which the Croats brought with them in the Migration Period.

The oldest found record of a Croatian Sheepdog dates from 1374, in which the Bishop of Đakovo, Peter calls him "Canis pastoralis croaticus".

Professor Stjepan Romić developed the Croatian Shepherd Dog as a breed in the year 1935.
