I have a ~47 lb Husky/GSD who is probably less than 1 year old, and was given up by an animal hoarder. Initially he was very skittish, and shy, but he has made a lot of progress.
My goal is to eventually take him and his 2-year-old Husky/Cattle-Dog friend Reggie out for walks together, but George has developed a problem with pulling as his self-confidence increased.
I have looked online at various dog-training advice, and I have been training him not to pull by stopping every time I feel a distinct tug on the leash. I ask him to come, sit, and look, in that order. If he refuses, I step backwards and pull him back with me. Once he passes all of these tests, I give him a treat, and we start walking again.
He has made good progress with this, but George has started to very very gradually increase the strength of his pulling, from just enough to keep the leash taut, to being hard enough to eventually give my hand some discomfort.
I don't care if he pulls a little bit, but I don't want my hand to hurt, and he builds up his pulling strength so gradually, that I'm not sure how to provide consistent correction. It's hard to tell at what point his pulling is strong enough to eventually make my hand ache. I could correct him whenever the leash isn't at least a little bit loose, but I am worried he may not be able to tell, and will be confused by the corrections.
How can I train George to stop pulling hard enough that my hand starts to ache?
