Our youngest one, Livvy (she's younger by 8 days), has a tendency to act like the bratty little sister. And, she is very attached to me. Probably because when we brought her home from Wisconsin (a 9 hour drive home) I held her almost the whole time up against my chest. She would not ride in my lap and would only last a short time laying next to Izzy. She wanted to be held.
Most of the time, the fact that she's so attached to me is not really a problem. Until someone else wants my attention.
I was laying on the loveseat the other day, curled up under the afghan. Both dogs were on the floor next to me. I noticed Livvy staring Izzy down. Then, all of a sudden Izzy tried to jump up next to me, but Livvy jumped faster and took the spot Izzy was trying to jump into. Then, she turned and looked down at Izzy again and stared at her until she laid down on the floor.
