All Shih Tzus do that so it is nothing to worry about, but i think it is suppose to clean their eyes like tears clean our eyes except their run-off is red so it stains the fur. I don't know why it smells sour. But for my shih Tzus, i use Angel Eyes, which is little powder you put in their food. It helps alot with the nasty smell and even clears up their face a little. It is a bit expensive though. You can Find it in some popular pet catologs and definetly online.
They shouldn't have runny eyes. It means it's fur is getting caught up into its eyes & needs to get a trim around its eyes from its groomer. After that, your shih tzu shouldn't have runny eyes.

Sour milk is milk that is off. You drink, you get diarrhoea. So don't drink sour milk.
