Everyone has such cute dogs!
At the last puppy play time, someone had a wheaton (weaton?) terrior that was just so friendly and wonderful and cute. That would be my second choice. I also like Australian Sheaperds, they are a lot like Border Collies. I just like smart, cute, energetic, loving dogs which is most of them :)
I have to say that when I see a rottweiler or dog like that...I am afraid of them unless I know the owner and the owner is a good one...but even still...
