How long does it take for a Yorkie's hair to grow?

How quickly a Yorkshire terrier's hair grows can vary in individuals, but it generally takes between four and six weeks for a newly groomed region to return to its original length. In certain regions, such as the groin, it is important to maintain hygiene and groom earlier than other parts.

The hair on the face of a Yorkshire terrier should not be cut until the puppy is at least 9 months old. Hair on the ears should be trimmed regularly, otherwise the fur can weigh down the Yorkshire terrier's ears. Hair in the ear canal is removed entirely to prevent infections. It is recommended to do this weekly due to the fast rate of growth in this area.
