While she doesn't have any articles about your situation exactly, you might find some ideas on Dr Mawer's website:

I don't have any dogs right now, but have four cats. They don't all get along all the time. I also used to have a dog with separation anxiety, as well as a dog with generalized anxiety.
Some things I have found that have worked in various combinations for some of the problems include Feliway plug-ins (this is a phermone), Royal Canin Calm food, Anxitane (which is L-theanine), Anzio VM Calming formula (a herbal liquid supplement), Amitriptyline (this is prescription), and currently the bully cat is on Fluoxetine (Prozac, also prescription).
Hope that helps!
