When do Yorkshire Terriers stop growing?

Most Yorkies reach their adult weight by 10–12 months. Skeletal maturity (growth plate closure) typically occurs around 9–10 months for this small breed — earlier than medium and large dogs.

How much should a 4-month-old Yorkie weigh?

A healthy 4-month-old Yorkie typically weighs roughly 1–1.8 kg, depending on their eventual adult size. Weight varies significantly — body condition is a more reliable guide than a target number at this age.

When should I switch my Yorkshire Terrier from puppy food to adult food?

Around 10–12 months is generally appropriate for small breeds like the Yorkie. Transition gradually over 7–10 days to avoid digestive upset.

My Yorkie puppy seems very tiny — should I be worried?

If your puppy is growing consistently and has good energy, body condition, and appetite, a small size may simply reflect genetics. If growth has plateaued, weight is dropping, or the puppy seems lethargic or refuses to eat, see your vet promptly — these are more concerning signs.
