Is there any drills or anything that will help a dog learn how to use his nose quicker? I have an 8 month old and he has been marked since he was younger but preparing for his first started test decided i probably should be throwing marks in a little taller grass. He marks well, but in the taller grass when he gets to the area of the fall he starts hopping trying to see the bumper over the grass. Today he would put his nose on the ground when he would wind it but it was like he didnt trust his nose and would just start running around in the area of the fall till he seen it. I didnt know if there was a drill to help with this or if he just needs more marks. Any help would be appreciated.
