Thanks for looking at our Shih Tzu puppies. Our Shih Tzus should weigh between 12 and 15 lbs, best guess 13.5 lbs as adults. The mom is 15 lbs and pops is 12 lbs. All our puppies come with a one year written health guarantee against congenital defects. Their vaccinations and de-wormers are up to date based on their age. We are asking $399.00 plus Tax and other fees, making it a total of $478.25, for our puppies, cash only. Card will be an extra fee of 100 dollars.
