Barney's Grandmother
I don't know if my mother will appreciate this post, but she truly was Barney's human grandmother. He stayed with my parents a couple times when my husband and I went on vacation. And since Barney had separation anxiety, he could not sleep in a room alone, he whimpered, barked, and howled. So my mother slept in the guest room with him. Barney on one twin bed, my mother on the other.
Like a grandmother with cookies for the grandkids, she always had a milk bone for him. We'd come to visit, and he'd go straight to the cabinet where she kept them. (He never quite figured out when they remodeled their kitchen and moved the box though!) He got a Christmas present each year and immediately went to sniff under the tree to find it. He knew what that Christmas tree meant!
When each of my three children were born, my mother came to help out for the first week. Although the human babies got plenty of attention, Barney made sure she never forgot her "first" grandchild. She petted him. Gave him food and water and paid attention while we were absorbed with the baby.
He never forgot it. You could tell he always associated "grandma" with positive feelings and nurturing - just like any grandchild would!
