Health issues in Japanese Chin may include luxating patellas, cataracts & injury to the eyes, early-onset heart murmurs and Brachycephalic Obstructive Airway Syndrome (BOAS).

While health testing does not guarantee that a chin will not have health issues at some point in their lifetime, it does provide proof of health at a given point in time. We use the following advice and tools to aid in making informed breeding decisions.

The OFA recommends 4 tests for Chin:
​At 1 year - patellar luxation
At 3 years - eye exam by an ophthalmologist
At 4 years - cardiac exam by a cardiologist
Non-age specific - gangliosidosis (GM2)

Individual results are available on the OFA website. When all tests results have been recorded a CHIC number is provided.
