black gsd

I have a 7 month old all black GSD, and he never barked at people or dogs until recently. I am feeling stuck on what I should do to stop this behavior. He isn’t barking aggressively, he is just very excited, but because of his size I am scared that people or other dogs will take it as aggressive...

I want honest opinions of what you guys think 1 being poor- 10 being great, obviously I think he’s a 10 but let’s hear the world!!
