My family had a big debate over Gonzo's name too... I thought the name was dorky, but I was forced into keeping it whatever you pick, it'll most likely just grow on you. It's better to take time to find the perfect name than to just jump on the first one you think of ^_^

"Tucker" is VERY cute! That's really funny, because my Aunt has a Shih Tzu pup named Ziggy, he's insanely adorable. They are the sweetest little pups. "Tucker" really doesn't look all Shih Tzu to me, even though his face looks like a Shih. I think you're right... my Aunts Shih is literally a walking little mop! "Tucker" looks like he has a little short-haired breed in him.
