What they did with the white dog was outrageous! Bless you V for helping that poor baby out.
I can't imagine how you're feeling with this new baby tied out there....
I think you're a nicer person than I and you have the right idea going to speak with them face to face. Perhaps with some "diplomatic" wording they will understand that tying their pet outside all day long (no matter what the weather) is just not acceptable! I'm hoping they're somewhat rational people and will do the right thing for this little poodle.
