Wow, hard for me to pick between the Cairn and the Collie, but I'll go with Smooth Collie, only because I'm spoiled now with having a breed that's so easily trainable.

If I got a breed that didn't learn things as quickly now or once learned wasn't as willing to do them in any situation, I might could get a lil' frustrated I think. I don't have the longest attention span for tons of repetition, so I need a breed that works that way too. Collies fit perfect. They've got good focus, learn quick and would get bored if you didn't move onto something new. Drill instructor mentality doesn't work well with them or me.
