The Redline K9 Bottcher Tracking Harness is a great tool to train dogs to keep their nose down while tracking without unnecessary force. One leg of the harness fits around the dog’s midsection and the second leg runs under the belly and is fastened to the collar. Depending on the dog’s skill level you may fasten your tracking line to the lower ring or run the tracking line through the ring direct to the collar. The Bottcher Tracking Harness also allows the handler to run two lines for better control.The Bottcher Tracking Harness is constructed of riveted top quality black leather and heavy duty hardware. The Belly strap is generously adjustable so one size fits all.
