Recall is the one command that keeps a dog alive, and it is much harder to build here than the guides admit, because the place you have to practise has loose dogs in it.
The standard advice still holds — long line indoors first, never call the dog for anything it dislikes, never call twice. The local questions are the ones nobody answers. Where do you actually train off-leash: parks, empty plots, six in the morning? What do you do when a stray comes at you mid-session? Has anyone built reliable recall on a dog that was already reactive to other dogs?
If you have a dog you genuinely trust off-leash in this country, I would like to know how you got there.
