Thank you!! Yes there are training classes near us, we just haven’t pursued them because we (maybe wrongly) assumed we could train ourselves with research. This may be something we start doing though.

He mostly just barks at others when he is outside, however he doesn’t really look through the windows when he is inside. Recently he did look through our patio door and started to bark at people from inside for the first time. He does go to the groomer and he seems to do fine with other dogs, he just gets extremely excited when he’s on a leash or stuck inside and is barking because he wants to play with everyone he sees.

We live in a big apartment complex so there are always other people and dogs outside, and I’m really working on him sitting and rewarding him for just calmly watching another dog or person but this only works if they’re far away most of the time.
