Dżok ("Jock") was a black mongrel dog who was seen waiting in vain for the entire year (1990–1991) at the Rondo Grunwaldzkie roundabout in Kraków, Poland, to be fetched back by his master, who had died there.

[1] A monument to Dżok is located on the Czerwieński Boulevard on the Vistula River in Kraków, near the Wawel Castle and the Grunwald Bridge.

[5][clarification needed] A small monument depicts a dog nestled within protective, outstretched human hands, extending his left paw to the viewer.

The inscription on the monument (in Polish and English) reads: "The most faithful canine friend ever, epitomizing a dog's boundless devotion to his master.

Throughout the entire year / 1990-1991 / Dżok was seen waiting in vain at the Rondo Grunwaldzkie roundabout to be fetched back by his master".
