A dog who flings himself at his crate door and is terrifically excited is not going to be the
dog for you. You want a
dog who is curious and interested, but not overly excited. Conversely, a
dog who is cringing in the back of its crate is probably fearful and insecure, and it sounds like you aren't familiar enough with dogs to deal effectively with either extreme.
While it's true that Goldens are generally great "people" dogs, so are many other breeds.
