OK Everybody, heres the deal. 2 yr. YL is solid as a rock on all handling drills- single T, double T,wagonwhell,cheating drills, all/any drills that pertain to handling. we've done them all hundreds of times. THE PROBLEM: lately, it seems as if he thinks out past around 75-100yds that he doesn't have to do what's commanded of him. In other words, he,s solid at whistle sitting out in field but, has started to do what seems to be flat out refusals as in going back instead of over or vice/versa or just kind of doing i guess what he thinks is the right move. the dog is a heck of a hunter. and is being trained at master level training. which he typically has good success with. Is this a common bridge to cross? as i have read before that when some retreivers get "comfortable" with their handling they will sometimes fall off course with things. If so ,ANY advice? thanks so much!!!!
