I began making Biothane lines when I starting training my own dogs on stock. I found it was the perfect material for a line that was constantly being dragged through barns, stalls, pens and pastures during herding lessons. Easy to clean, quick to dry and no more rope burns! Soon friends and people at clinics and trials were asking me to make them lines as well. I'm proud to offer simple, practical yet high-quality equipment that helps people train their dogs to do more.
