The mom weighs 4 lbs the dad 5lbs your puppy was 1 lb at birth how big will your yorkie get?

The size of a Yorkie can vary, but generally, they tend to be small dogs. Given that both parents weigh 4 lbs and 5 lbs, it's likely that your puppy will grow to be somewhere within that range, potentially around 4 to 7 lbs as an adult. However, genetic factors and individual growth patterns can influence the final size. Regular veterinary check-ups can help monitor your puppy’s growth and health.
