I have been having a problem with doggie beds too! When Abby came into our family in July we bought a new pet mat for her. Buddy already had one which he slept in everynight and at nap times Ect. So Abby goes in Buddys bed or on occasion her own (seldom). And she won't get out of it either! Buddy looks so disguested! And goes and sleeps on my side of the bed on the floor. I really don't know if its the alpha thing but, I think in my case Abby sleeps in Budddys bed because it smells like Buddy!
