[Gpdd] Behavior: sudden dominance

[dogcatpiggymom at yahoo.com]

Thank you, ME, for letting me know you've seen this behavior, too.
Sweetie was born approximately January 2008.  Her aggression
calms down when I separate her from the girls for a short time 

and then return her.  I can always tell when she is aggressive with
them because they all squeal this upsetting sound.  I hope it stops!
Thanks again,
Joanne, Merri, Teddy, Baci, Sweetie, Sassy, Ellie
