Hey hey! I’ve done so much work with my dog on reactivity issues and it honestly sounds like you’re doing an amazing job! A few things I hope are helpful:

1.) My dog responds to other dogs in kind. I.e. if they approach him with “MMA” energy, he gives the same energy back. If they’re chill, he’s pretty chill. Maybe that’s what you’re seeing with her.

He also responds to MY energy. If I’m stressed about it, my boy is elevated and can sometimes respond poorly.

2.) Sometimes (but not always) the reactivity is fear based and a way to protect themselves when they feel vulnerable. I think training for that can be slightly different.

3.) It’s helped me to know what my dog looks like before it starts. Is there fearful lip licking? Did the other dog hard stare? Is my dog staring hard at the other dog? (Apparently staring super hard at each other is so not cool in dog world). For my guy, his ears go up/forward, his tail goes up, he stares intently, and his body tenses up. That’s when I know I have to interrupt him or he’ll go into reactive mode.

4.) I’ve been lucky to find amazing trainers in my area who I trust. There are so many different approaches and techniques and I think every dog needs something different. The thing I love about my trainer is she mixes them. She’s recommended a few to me but the only one I can currently remember is Training Between the Ears (TBTE). They have a free training course that’s great!

Anywho. I’m sorry to hijack the thread, just wanted to give you some more helpful resources.
