The dataset contains a description of wolf-dog hybrid scat content used to assess the diet composition. Scats were collected in two study areas (Radomsko and Szubin). Scats were placed in paper envelopes and then dried in laboratory dryers for five days at 70°C. Afterward, scats were soaked and washed through a fine 0.5 mm mesh sieve. The dried remaining material was weighed. The food items were identified based on the presence of hair, fragments of bones, hooves, claws, teeth, and feathers, using specialist keys, as well as comparison with our reference material.
