I expected Marty to be the Top Dog when Bea came into the house. Bea is coming out of her shyness and expressing little challenges (not serious ones). Can I help keep Marty in top rank position or just let them establish the order themselves. Marty is a very loyal obedient trusting dog and I wanted her to be the role model for Bea who only raised babies in her life. Time for doggie school????? Bea is 5 and Marty is 6, both spayed. When I had two other dogs before Bea, Marty was not the top dog out of 3.
