Many dogs have clearly different paw prints than wolves. Often they are smaller, some have also clearly rounder paws. But there are also dog breeds where you cannot distinguish single paw prints from wolves.Only a sequence of footprints followed for a significant track on the snow or sand allows (always with a margin of uncertainty) the distinction between wolf or dog through gait recognition, which in some cases is characteristic (in the wolf the front and back legs move on the same line). In any case, in order to distinguish a wolf track from a dog track, molecular genetic analysis on the biological samples collected along the track (scats or urine) or an image/video of the moving animals are always necessary (e.g. by camera trapping).
