When Does A Yorkie Reach Full Size?

Newborn: Birth To Two Weeks

A puppy Yorkie weighs from 2.5 to 5.5 oz at birth then grows up rapidly to reach 6-13.5 oz by two weeks. During this period, the puppy depends completely on its mother because its eyes have not yet opened. Also, it can not crawl, just doing a sort of stomach scoot when looking for its mother’s milk.

It expresses its distress by making a little mewling sound. Yorkies during this stage spend most of their time sleeping. Additionally, you can see their sizes get bigger rapidly in just a few days.

Infancy: Two Weeks To Eight Weeks

The weight of a Yorkie’s puppy during infancy can reach 12-32 oz by the age of eight weeks. During this stage, the eyes are opened and the ears function well so they can explore the world around them. They start to crawl in a drunken, wobbly way then climb out of their bed to play with their siblings.

They can lap up liquids so it is a good chance to introduce some solid foods gradually and slowly. Some breeders wean the puppies completely from their mothers’ milk by eight weeks however, others prefer to wait till the age of 12 weeks. It is recommended to start potty training during this period although it will take some time to succeed on this mission, potty training is challenging in Yorkies.

Puppy Time: Eight Weeks To Six Months

The weight of a Yorkie puppy reaches 10-27 oz by the end of six months. During the puppy time phase, you will watch the active Yorkie that enjoys wrestling and playing. It will also be more vocal as its voice develops and will use it to tell you that he needs something.

Yorkies could sleep around 18 hours or more during the day as long naps and yawns to get some rest from the excessive playing. They start to be more confident so make sure to socialize them properly with people and other pets. Also, you can see their stride opening up, their ears stand up, and their baby teeth start to fall out.

Teenage: Six Months To Two Years
