How will you know if your pet is not a crossed breed shih tzu?  

I do not have one of these adorable dogs but wish I did. However, to know if you have a purebred dog you would have to have the papers with it stating its pedigree. Without that you cannot be sure. If they lie about the pedigree then I am sure there are fines involved. Of course if you want the papers, you will pay higher price than you would for one without papers.

hi there, the best way to know is with the pedigree, papers and if you are able to se the parents would help to also getting your puppy from a known breeder. i had my first pet a shih-tzu and got him in 1999 he died a couple of months ago. i just got new ones, male and female they are adorable and a ton of work to train but we are getting there. good luck if you get one.
