I see it everyday driving or walking people trying to manage their dogs, as their dogs are walking them pulling in every direction. As well hear say and reading, shows me people have an extreme amount of hardship with this task. Every dog I encounter takes me about 3-5 minutes and we are on a loose leash, well besides one case he is a Labrador Retriever. He came around it took me about 2 hours. It just confuses me probably like some simple problems confuse me.
