The eight seconds before the lunge
Owners describe reactivity as sudden. Slow the footage down and it never is.
Every owner who writes to us about a reactive dog uses the same word. Suddenly. He was fine, and then suddenly. We asked four behaviourists to watch the same eleven seconds of phone footage, filmed on a towpath in Stalybridge, and mark the moment the dog decided.
All four marked it within a second of each other. None of them marked the lunge. The earliest was at 00:03 — a head turn so small the owner, three feet away and holding the lead, did not see it happen and has never seen it since.
What follows is a translation. Not a technique, not a protocol, and emphatically not a fix. Just a list of the things your dog is almost certainly already telling you, in the order they usually arrive.
