When helping out a dog on a mark that they have put up a good hunt on but just can't seem to find, and start to return or get out of the area of the fall, what kind of help do you give them? I will start to walk to the bumper and yell to get their attention and pick the bumper up and throw it up in the air so it will land in the original area of the fall. I have seen other trainers yell and act as if they were throwing another bumper, throw another bumper in another area from the original and a few other methods to get their attention. What if any is the best method to help on marks? I also know if the problem continues you need to shorten the marks.
