I, for one, am fascinated by the hairstyles given to Shih-Tzus. In particular the "top knot" seems to be the thing to do with this breed.
Although my boys have short hair, I've found some links for those who are a bit more adventurous and want to give their dog a bit more panache.
1. Shih-Tzu top knots - illustrations of how to tie the top knot, show knot and puppy knot.
2. A casual Shih-Tzu top knot and the illustrated guide to the Show knot (curling iron required. Really!)
3. One of the most fabulous pics I've seen of a Shih-Tzu. I have no idea how they got the dog to look so perfect, but I suspect it took quite a few hours and hairspray was involved.
