We're Sheltie people, too. Ours is Major and he's absolutely perfect.
We also have our Karankawa lap dog, Lucy. She looks like a little fox, is the only female of the household except me, and rules the roost.
The watch dog is Clancy the Collie. Yes, he's named after Tom. He was Lassie when we got him, but we thought he'd prefer a masculine name. The challenge was to think of a masculine name which sound somewhat like "Lassie."
I'll post a digital photo soon. I don't have a recent one.
