How big do shih tzu dogs get?

Normally around 10-15 lbs and about 11 in. from the base of the neck to the base of it's tail.

For reference, about the size of a 6 month old child.*


*It is not recommended that you have, adopt, steal, or otherwise obtain a baby, just to know how big a full grown shi tzu will become. Babies take approximately 9 months to create, plus the six months for it to reach a shih tzu size.
