Mortality
The
life span of a healthy Yorkie is 10-15 years.
[34] Extremely under-sized Yorkies (3 pounds or less, and often promoted as "Teacups") generally have a shorter life span, as they are especially prone to health problems such as chronic
diarrhea and
vomiting and are more easily injured.
[34] Even the normal small size of a Yorkshire Terrier means that it can have a poor tolerance for
anesthesia, and it is more likely to be killed or injured by falls, other dogs, and owner clumsiness
This is just normal life span, can be less can be more.
