I’m pretty tired of my dog being a frustrated greeter

My dog is a German shepherd husky mix who is 2yrs old. Since he was a pup he’s been a frustrated greeter and reactive in other ways. Whenever we see a dog, I get anxious bc he will usually react 95% of the time. He’ll bark and prance which scares other owners a lot. It’s super embarrassing and frustrating to see owners that we pass by whose dogs don’t react at all.

I’ve done so much training and he is not treat motivated at all. Very toy motivated but it worked only momentarily. I’m not sure what to do about this or how to train him on it since he’s my first dog ever. Also, he’s a tugger which makes things a ton worse. Any tips, videos, anything really will help please <3
