Yes, I'm glad to hear differing opinions! We're keeping our options open but leaning toward a purebred waterdog of some sort. I'm sure I'll be back later with questions about how to integrate a new puppy in to a home life ruled by a cat (and with an African basenji in the mix)... :)
The golden I used to have did similar things w/her ears/eyes when I approached w/a leash. It was a habit formed from years of me sliding a new collar on with the leash attached. She'd squint and pull her ears back in anticipation of the collar being slid over her head.
The smile? I never got that.
That is a happy ending! My SIL's boxer ran out the door one Christmas morning at the other SIL's house. We all watched in horror as she dashed into the street and ran INTO an car. She bounced off the passenger door, and seemed completely unphased!
