What is considered full grown for a toy morkie?

A toy Morkie, a crossbreed between a Maltese and a Yorkshire Terrier, is typically considered fully grown when it reaches about 4 to 7 pounds in weight and stands around 7 to 9 inches tall at the shoulder. Most Morkies reach their adult size by around 1 year of age, although some may continue to fill out slightly until 18 months. Factors such as genetics, diet, and overall health can influence their final size.
