Melissa is correct, never let anyone approach you. Usually simple as “my dog isn’t friendly” and they’ll stay away. I would continue trying some group classes, and if your teacher is prepared they should try keeping you behind a barrier if she is reacting badly. Let ginger start hearing and smelling other teams working around you, and gradually go into it that way. A shy dog class could be of use as well. Start learning what triggers and counter them with positive encouragement.
When you’re walking, keep your distance, but when another dog starts walking by, try some high value treats. It won’t help overnight, but keep reinforcing that another dog walking by is not a bad thing. Work on getting ginger to focus on you, and not on the dog walking by. And again, never let anyone approach you or you will continue to feel frustrated, and it’s not really her fault when that happens. I have one that isn’t necessarily fearful but doesn’t like strange dogs in her business, and I’ve been known to body block on walks when people who don’t have a recall decide to walk off leash 🙂 get comfortable doing that as well
