To painiacs - when we got our second dog, our trainer recommended that we continue our main attention on our first dog so that the first dog wouldn't punish the second dog for taking her place. When we came in we always acknowledged the older dog first, gave her a treat first. Eventually it all ironed itself out. Now dog 2 rules the nest. They figure it out but we didn't like the baby to have to defend herself against the older larger dog. Babies grow up and the field is leveled.
