Our collie Jay is so attached to KYHillChick that, as he ages, he now just lies on the floor when she goes shopping and watches the back door. His whole being seems to be focused on that door. He ignores me. He even ignores squirrels playing on the patio. About a minute before she walks in, he gets up. He can hear her Chevy coming up the road. When she comes in, his life resumes.
