As a breed, the Japanese Chin is generally a healthy, happy, affectionate and playful dog.
It cannot be stressed too strongly that it is always recommended that you purchase puppies from a recognised quality breeder, where the health and welfare of their puppies is a priority. Puppies should be fully inoculated and microchipped before leaving home.
Unfortunately, as with any living creature, unforeseen problems can arise. The most common of these are patella and heart problems.
Currently, the Japanese Chin Club along with the Northern and Southern Japanese Chin Clubs are preparing to form a Joint Health Committee to help coordinate and monitor the health and well-being of the breed. This would involve regular opportunities for breeders to have their dogs tested for any health issues that the clubs feel need to be monitored, and a central database that would keep records of all tests done.
Hopefully, you will have a lovely, healthy happy companion with whom you spend many happy years.
