Donht be to worried about the zoomies....My goofs do it too and theres a huge dent in my brand nesw shed where Mojo crashed into it !! The 2 dogs playing is a good sign hes not fased by her or dog aggressive so thats a win. Jumping is what does the real damage but that dosnt sound like its a issue for you.
Dont let him graze....as in eat when he wants. The other issue with this breed is they can easily get Bloat which will kill a dog quickly.....gulping food then heavy playing or running can twist thier bowels over then its pretty much lights out if not caught quickly. Its for this reason both my dogs are fed at night only, seperately then seperated for the rest of the night. They just chill out and snooze after dinner...but they both still gulp thier food quickly.
Try taking his food away after 10 minutes or even less. He'll soon get the message to eat it or loose it. But i stress the dinner only at night time thing. A frozen marrowbone or cow hoof during the day is good for them too.
I'm no behaviour expert sorry. What you should do is start another thread about his anxiety and the people here who know lots about that stuff will see it and no doubt help you out. Call it "anxiety issue" or somthing like that and the experst will be on it sooner or later. Good luck.
