This situation is frightening for all involved whether your with a Trainer or not. This is frightening for the Dog and the owner. It's OK to say my Dogs friendly but in this case it wasn't and could of ended badly. Please keep encouraging people to keep their Dogs on lead, if they have no control or management of their Dog. Especially in an area where there are also signs requiring Dogs to be kept on lead.
Everyone wants to enjoy taking their Dog for a walk be they reactive or friendly in a safe way. Nobody wants to see anyone get hurt. If you do have a Dog with no recall or reactive issues and don't want to seek out a Trainer please seek out an enclosed Dog field. There are so many up and down the Country now and it will help you to allow your Dog off lead in a safe way with no incidents. When not using a Dog field please just use a lead .
