The American Kennel Club lists Yorkshire terriers, or Yorkies, among the most popular breeds in the United States. Their small size and adorable looks are certainly draws; their brave and energetic personalities are endearing, too. Yorkies are popular with people who travel and people who live in small residences, because they’re able to adapt well. In general, Yorkies grow between 6 and 7 inches high at the shoulder, and their adult weight is around 7 pounds.

Yorkies Are Fully Grown at a Year Old

When your Yorkie pup turns 1 year old, she is considered an adult. About this point in the dog's life, it will be OK to switch from puppy food to adult food, but get your vet's approval first. You should have seen your vet a few times throughout the dog's first year; take the dog for another exam and get your vet's blessing to gradually switch to an adult diet. Although she has entered adulthood, your Yorkie may continue to gain and lose weight depending on her diet.

Estimating Your Yorkie Puppy’s Adult Weight

You can estimate your Yorkie puppy’s adult size by doubling her weight at 3 months old. For example, if she weighs 3 pounds at 3 months, she’ll likely weigh around 6 pounds as a healthy, properly fed adult. A healthy dog's ribs should be palpable; if they're not, the dog's overweight.
