Shih Tzu Age Calculator — Dog to Human Years

Shih Tzus are a small breed with a lifespan of 10-16 years. As small-breed dogs, they age slowly — a 7-year-old Shih Tzu is about 47 in human years, and they typically don't reach senior status until around 10-11 years. Originally bred as companion dogs for Chinese royalty, they thrive on human companionship and indoor living.

Brachycephalic airway syndrome (due to their flat face), dental disease, eye problems (including progressive retinal atrophy and dry eye), hip dysplasia, and intervertebral disc disease are common in Shih Tzus. Their prominent eyes are vulnerable to injury, and their short snouts make them prone to heat sensitivity and breathing difficulties, which worsen with age and weight gain.

Keep your Shih Tzu at a healthy weight to minimize breathing and joint problems. Use a harness rather than a collar. Regular eye care, daily face fold cleaning, and professional grooming every 4-6 weeks are essential. Senior Shih Tzus need comfortable orthopedic bedding, ramps for furniture access, and regular veterinary monitoring of heart, eyes, and teeth.
