Ebony has had some fear issues over the past 3 or 4 weeks, but seems to be adjusting now.  The panting and drooling that we used to observe has pretty much gone away and he is much less jumpy when there are loud noises, etc.  His pacing has stopped and another side of his personality is showing - he has gone from being shy and submissive to being confident and dominant over our other dogs.  The dominance hasn't been a problem, in fact we see some signs that it may establish a more relaxed environment for the pack in general.  since we are very iinterested in this sort of thing, we will report our observations as we go along.
