The black dog didn’t only torment the residents of the city center; it also caused trouble for the people of Gosławice. The hound was most often seen near a small shrine along what is now Wiejska Street. Nearby, there was also a school built on the grounds of a former cemetery (a common practice in the region, as was the case with the original building of Public Elementary School No. 1 on Marek Prawy Street in Strzelce Opolskie). It is said that, in addition to the black dog, passersby would often encounter an enormous white goose – the symbol of death. Any homeowner who saw the bird near their house could be certain that a close relative would soon pass away.
