On average, Yorkshire Terriers live between 13 and 16 years. The lifespan of “teacup” Yorkshire Terriers, who typically weigh under 3 pounds, is less than that of a typical dog of their breed.
There is no such thing as a Teacup Yorkie dog breed. In reality, teacup Yorkies are Yorkshire Terriers that are too small. Although they can potentially become this little by accident, they are typically small owing to breeding.
Teacup Yorkies can have the same health issues as larger Yorkies, including bronchitis and intestinal issues. Additionally prone to hypoglycemia are teacup Yorkies. Due to their small, they are extremely vulnerable to mishaps that a dog of a normal size would quickly recover from, and they can suffer fatal injuries as a result.
