The Japanese Chin is one of the Toy breeds – dainty looking but typically full of charm and liveliness. He is not demanding in terms of exercise and is happy to live in most types of home. His profuse coat sheds considerably and needs frequent grooming. Like all Toy breeds young children should not be allowed to pick him up or handle him excessively. It will not be pleasant for him and he could easily be injured.

Ask the breeder about the medical history of the parents, grandparents and great grandparents. Consider carefully whether to purchase a puppy if some of these or other diseases are in the family line.
Ask about the breeder’s policy in cases of serious genetic diseases occurring to your puppy in later life. Good breeders will request to be informed of such events in order to improve future breeding decisions. Some breeders will also agree to contribute towards medical costs or refund purchase price.
