Japanese Chin stand about 20 to 27 cm (8 to 11 in) in height at the withers and weight can vary from a low of 4 lbs to a high of 20 lbs, with an average of 7 to 9 pounds being the most common. The American Kennel Club and the Fédération Cynologique Internationale give no weight requirement for the Chin.
This breed's flattened face contributes to a few Chin suffering from breathing and heart problems, as is common with brachycephalic breeds. Because they are a brachycephalic breed, temperature extremes (particularly heat) should be avoided. Luxating patellas (knees) and heart murmurs are other genetically predisposed conditions. The oversized eyes are easily scratched and corneal scratches or more serious ulcerations can result. Mild scratches benefit from topical canine antibacterial ointment specifically for eye application; more serious injury or ulcerations require urgent medical care. The Chin, as with most small breed dogs, can also have a risk of hypoglycemia when under the age of 6 months; this concern can continue in Chin that mature at 4 to 5 pounds or less. Some Chin do have seasonal allergies.
