PROTSIONUS URSAMBOL: blood tracking time: 24 hours, length around 700-800 m with 4 curves, used blood: 200 ml on sandy ground. Honestly, after one day I not found blood. Before tracking we did obedience with 3 shots without fixing. At the end he tracked alone (40-50 m), wind not helped the work of URS! The work was interesting and perfect.
