Having been owned by them for over 30 years a Yorkie is usually full grown(size) between 10 and 12 months of age,height wise,they can fill out more depending on how a person feeds or over feeds them.

no. a maltese is fully grown at one year of age
I would recommend starting to breed a Yorkshire around the age of 2, so their body can fully mature.
A marmoset monkey is fully grown at 15 months of age. They are already sexually mature at this age but are unable to breed until they are dominant.
How would you know it wasn't fully grown? It is most likely that it will not get noticeably larger.
