I was just kinda looking at the Daily puppy, and found this thread on Border Collies. Our Whisper was one. Sadly we only had her a little while, because they didn't give her the medication she needed for her epilepsy while she was in the shelter and the frequent seizures had damaged her heart.
One of the "things" of the Border is that they stare at the animals they have to herd and keep track of. That's why this answer in the thread just had me roaring laughing:
My friends' working BC had an accident a year or so ago and was on house rest while his leg heeled. He got so bored he decide that his job would be to know where the cat was every second of the day. He didn't herd the cat or do anything except stare at it. If you sat in the way he would peer round you or move until he could see the cat again. Thankfully he is now out working sheep again and the cat is relieved.
PS: I'll update you on the weekend after my nap... YUP! I'm still in recovery.
