A little more on this. I took my dogs for a walk this morning, at the river which we do on weekends, and which is full of unpredictability and distractions from people, other dogs, deer, coyotes, bikes etc. It is a good place to have the dogs follow me and not get fixated on something out front.
I used this (old school) technique to prevent forging:
I usually walk the dogs one in each hand, but to turn about quickly, both need to be on one side.
When we go off on our walk and they forge, and I give a quick pop and go the other way (for at least 10 steps), they are following me for those 10 steps, till I turn around to continue, where they would follow for a bit (slightly behind me) then tend to forge. I just now got the idea that I should continue that 10 steps where they are following and praise them highly when they do that.
I wish I had thunked of that on the walk, but anyways they did very good with that approach and for the most part were a tad behind my leg, ears down, looking relaxed and content to follow. They were quite easy to handle with this approach.
Riku, who is my big dog and who is quite high strung and dog reactive, was the one who tended to forge, while Tuki hung back by my leg. When I did my sudden turns I was careful to give the correction (a light pop) to the forger.
