To achieve these health benefits, CaOx urinary stones need to be recognized early prior to the development of clinical disease. We can help.   Males are affected more than females.  Around the world the most common breeds that form calcium oxalate are the Maltese, miniature Schnauzer, Shih Tzu, Yorkshire terrier, and Chihuahua.  The most common age for the onset of clinical disease is 7 to 8 years.  We recommend to begin screening (i.e. medical imaging) high risk dogs at 5 to 6 years of age.
