Question: are shih tzus prone to cysts?
Answer: Multiple and recurrent follicular cysts may develop on the heads of young dogs. Boxer Dogs, Shih Tzus, Schnauzers, and Basset Hounds have a genetic predisposition for follicular cysts, but they can occur in other breeds as well. Comedomes can develop secondary to exposure to drugs such as glucocorticoids (steroids).
