Skin problems due to allergies is a life long problem for any animal of any species. And yes it can be hereditary. Unfortunately, Shih Tzu's a high on the list for being allergic dogs. Even if your breeder has had several generations without allergies it does not mean that your dog will not have them.
The good news is that they are coming out with more efficient treatments all the time.
To start your puppy off right get him or her immediately on grain free puppy food containing meat, fish or poultry with vegetables and fruit. Begin giving the following as food supplements soon after you get your puppy: a vitamin and mineral supplement called Missing Link , Colostrum, and a probiotic (good bacteria supplement). Double your dose of the probiotic any time your puppy has to have an antibiotic or anti-parasitic medication. Use Revolution as your flea and tick repellent and heartworm preventative for at least one year. Have your dog only vaccinated with the recommended regimen for the first two years, than request that your vet perform vaccine titers. It has been shown that some vaccines last much longer than only one year.
If your dog does develop skin disease see a board certified veterinary dermatologist ASAP. This will more likely keep your pet off the steroids longer. Have allergy testing if deemed necessary. Stay Proactive!
