Wow, this was exactly the information I was looking for myself. Ditto what the OP said to begin with as that is what I am looking for. I was wondering if the herding dogs like the Australian Shepard or the border collie would be too smart for us and as we both work full time, it does mean that they would be alone for a good part of the day. (well there are dogs and cats and birds and such but not people during the day)
