ROFL.
Damp understands far more English than we do Danish, I can assure you of that!!!!! She's also forgotten more about dogs than many of us, including myself will likely ever learn.
In damp's no nonsense way, she stated that it does not matter WHY, it matters that we do not allow this behavior.
For those of you interested, unless there's a bitch in heat standing underneath the dog, it is dominance.
Again, it matters not WHY, but that it is simply not allowed.
