Sorry BionicEmu I'm in Devon,
I would also recommend the going backwards tactic , don't turn round, stop, (with me) walk backwards,for about ten yards , holding hand on thigh, you can add a 360 degree turn, stop and start again.
I do recommend a well walked dog, most dogs are really under walked, so are gagging to get out and about,
Dogs that do the same walks all the time, are always desperate to push boundaries, as they need new information, to a dog if you do the same walk all the time, it the human equivalent of being give the same copy of chat magazine every day, it would drive you insane, dog's confidence is built on their knowledge, they need lots of new information, to feel calm and settled.
Build a complete mind smell map, explore every inch of the surrounding area, your dog needs to know where the fox goes after the it crosses the road, it needs to know what going on around the corner you never go round.
Walks and excise are two very different things, dogs need to have at least of three twenty minutes of hard excise a day, that is when they pant hard because they are working hard.
Walks are information gathering, it's their news and TV. They need at least two really good ones a day at the minimum.
