Thanks Pam, Kay and Dogz!

I gotta go with Collies, but I can see myself someday getting a
Sheltie, as I get older and it's more practical to have a smaller
dog.

As to Rough vs Smooth Collies, I've never read that Smooths
were more intelligent. I have noticed that the Smooths seem
to have a lil' more pep to their step, which I think may have
something to do with coat type, as they don't get overheated
as quickly. In the old days, when Collies were still primarily
working dogs, the Smooths were mostly used as drovers of
the sheep to market, because of the overheating issue with
the Roughs.

Anyway the Roughs and Smooths can come out of the same
litters, so I don't think there's a huge difference in temperament
between the two.

As to stubborn, I do see that in Oz. He wants to please you,
but he's not going to be *made* to do anything. He digs
his heels in on things he doesn't want to do and I really have
to work to make them seem fun, so he'll want to do them.
I've used only positive reinforcement with him, but I've seen
him shut down when he's gotten stressed over something,
so I think anybody who took a "I'm gonna show you who's
boss" attitude with him, would get absolutely nowhere. Collies
are sensitive and I think it would be very easy to lose their
trust if you tried any of the harsh training techiques on them.
