Ill give you a little more information. Mine (Geordie & Callie) are fed separately from Lexi. The problem is between Callie and Lexi. Their bedroom and feeding area is upstairs. Lexi sleeps downstairs with her parents. When i wake up, i feed them and take them outside. As Callie goes down the stairs in the morning, she raises her hackels in anticipation of seeing Lexi.
It used to be that Lexi would already be up by the time i take them out in the morning but we have begun keeping them in the downstairs bedroom until my morning stuff is done and we can find a resolution to this morning problem.
When all together, like at the dog park, the run as a pack and seem to get along very well. Also get a long great at night playing. I try to do exercises with them and praise them for any good behavior when they are all together.
As far as improvement, I have seen alot since we first moved and since i first got them. Both of mine were rescues from BRAT. They have come along way and i really want to work this problem out. Ill give them all the time and patience i can.
