Hi, Mary Mc & welcome. Tiger sounds a great little dog. Many of the dog breeds from the Far East, like Pekes & Shih-Tzus & Tibetan Spaniels have bottom teeth that stick out. But they don't have pointy ears...but Papillons do.
It'll be great when you're able to post a pic of Tiger. You must be proud to have such a unique & intelligent little dog.
I live in Queensland, Australia...on the opposite side of the continent to you.
