@Quercus:
Interesting, and good to know. Did the Benadryl just make him sleepy?
Nope, but it did seem to have a calming effect. When I added the Benadryl, I was still webcamming him, and I noticed that with its addition, he was not so restless. He was able to lay down for up to a 1/2-hour or so at a time. This was before adding a lot of the "distraction" stuff to the mix. Once I saw that the distractions were, indeed, keeping him distracted, I stopped the Benadryl.

…it just goes to show you that with patience and perserverence our dog issues CAN GET RESOLVED...Thanks for inspiring myself & maybe others. You've managed to keep me motivated to keep at it with my little ones
To be completely honest, Magnum is MUCH better than he was at first (over two years ago), but I can't say that he's completely SA-free; he still doesn't really like to be alone. He IS, however, much more comfortable in being alone. So I consider his SA to be "managed" rather than "resolved."
I'm glad I could help a little.
