hey i have great success with my dog chase, hes phenomenal but I have this other dog bud and I feel he could be so good but he won't listen to me..... he does not bite, but when i take him near sheep he heards them into a mob them keeps them surrounded and is laser focused on doing that but hes not following a single command i say and he is not moving them sheep to destination just keeping them circled..... he will take off after sheep to do this.... i have been trying and trying and all i can do is that he will stay and come here when on my lawn with no sheep visable or 4 wheelers or utes moving..... I really don't think the dog is a dud I just do not know what else to do except an electric collar but I am not really into that type of thing. I do not ever hit the dog etc I just do not know how to get through to him. Any advice?
