Just a thought on the personality thing. When I initially went to look at the puppies at shelter, I had a choice between Ginger and her sister. Ginger was the more lovey one, her sister was runnig around getting into everything. I left the shelter to think it over while having a bite to eat. I decided that the sister may be too much for me to handle, and decided to take the quieter baby. When I got back, only Ginger was left (good thing she was the one I decided on ). Anyway, I bring up the personality thing for two reasons. First, Ginger is a very timid dog, she is afraid of people and large lawn ornaments (don't ask). So if you are still thinking of therapy, he may be to timid. However, put her on an agility course, or in a dog run with other dogs, and she comes to life. She loves it. I mention this because you said the blue boy may be too laid back for those types of activities. I guess what I am trying to say is that he may be Aussie enough to really come alive at such activities.

No matter what you decide I am sure you will have a wonderful dog, and he will have a wonderful home. Keep those pictures coming.
