Okay... So many cool new suggestions... I really like Suss, Kuchen, Zucker and Schatzie... My mom would mangle the German, though... "Koochen" and "Zuh-ker" just don't sound nearly as sweet as they are in the original... "Suss" would work, though--she'd say it like " Dr. Seuss." "Schatzie" would still sound fine, too. We'll see!
As my mom mentioned, "Heidi" wouldn't work because of our neighbor's dog... and "Sophie" is the name of my friend's French/American daughter; we now think of the name more as French than German.
Please check out Cecelia's blog for pictures from the puppy's first big day out and about. She was taken to church and is being spoiled wonderfully rotten!
