Average lifespan: 13 years (10–16 years) · Small breed
The Shih Tzu has a lifespan of 10 to 16 years, with an average of about 13 years. This wide range reflects the significant variability in health outcomes within the breed, largely depending on genetics and quality of care. Well-bred Shih Tzus from health-tested lines often reach the upper end of this range, while dogs from less careful breeding programs may face more health challenges.
Originally bred as companion dogs for Chinese royalty, Shih Tzus are a mildly brachycephalic breed with large, prominent eyes that are highly vulnerable to injury and disease. Corneal ulcers, dry eye, and other eye conditions are among the most common reasons Shih Tzu owners visit the veterinarian. Their luxurious coat, while beautiful, also requires dedicated grooming to prevent painful matting and skin infections.
Dental disease is another significant concern for Shih Tzus, as their small mouths lead to overcrowded teeth that are susceptible to decay and infection. Portosystemic liver shunts, though less common, are a serious breed-specific condition that can affect puppies and young dogs. With consistent grooming, dental care, eye protection, and regular veterinary checkups, Shih Tzus make loyal and affectionate companions for many years.
