Shih Tzu Hound Dog!

You may all laugh at me, but I am new to this breed, and had the most fantastic, laugh out loud moment today. Our little foster Boris (who we call Oliver) was waiting for me to unlock the door this morning, and I apparently took too long. He sat back on his legs, and from deep in his stomach came this throaty, deep HOWL, like an old hound dog! Shih Tzu dogs can howl??? OMGoodness, this little dog - where on earth did that sound come from? I can only hope he will do it again, it was hilarious!
