dog body language and communication

can any body help me with this topic i am interested in what the dog isaying
and i hear that dogs speak exclusively with body language

yes its interesting and yes its true dogs do communicate by displaying
body language.
they also communicate vocally ~ bark,whine,growl,moan.

what was it you wanted to know about communication and behaviour or was
it just that you wnated to know if what you heard was right?
