The first thing I do when I see a dog lunging and going all cujo like is make sure halo is right up against me. I'll keep walking and keep her focused on only walking which she naturally does very well but she has her occasional puppy slip up
If the dog happens to be on the same route were on like theyre.behind us. I usually cross then road. Of find a.different way to get where were going. Most of our walks are cross country but we have to travel the huge complex we live in to get to it.
