While training with my dog tonight I noticed a habit she has that I thought I would share. I was throwing marks for her and after she brought back the mark I would send her to a big pile to pick up a bumper about 100 yards in front of me. At one point on the way out to the pile my dog stopped and urinated. Every time I sent her back to the pile for the rest of the training she would get to the point where she urinated and go around it. She would get right back on line to the pile but she always avoided the area where she peed. I have noticed her doing this in the past with her waste and waste from other dogs. Is this good to let happen?
