I’ve had shih tzus for 30 years and have tried all diets (we eat organic ourselves). Watch out for yeast if problems with dry skin or itching, may be also related to stomach issues. It looks like you can find lots of foods with high ratings here. We sometimes cook for our dogs – ground turkey, oatmeal, some veggies, olive oil. Make a large batch & freeze some – we do this to use all organic products. My dogs also do fine on a high quality dry food & wet food mix. I mix it up, add a bit of eggs when we eat them. One dog was allergic to beef. With a small dog like a shih tzu it’s easy to give them bits of healthy (fish, meat, sweet potato, cheese) leftovers too as a supplement (though some people never spoil their dogs like this!)
Good luck – these are fabulous, loyal, loving dogs!
