I've been trying to train Milo to walk to heel on a loose lead but its proving difficult. We go to a training class but we haven't done much on walking, more so the beginnings of it. He'll sit in the heel position and walk a short distance inside without a lead and usually with but when it gets to outside, it's a whole other story. Though he pulls a lot I have to gently tug as well because he's so curious he stays behind to look at a leaf. He seems to find it hard to give me attention when out on a walk and never looks at me, even when I say his name, click, give the recall sound, etc. Other than that his recall is pretty good. I'm just so frustrated!!! I don't know where to even start and every tutorial I look at or watch seems to say something different. Suggestions?
