When do Tibetan Terriers stop growing?

Tibetan Terriers stop growing around 12 to 14 months of age, although some may continue to fill out slightly until they’re about 16 months old. They reach their full height at about the nine to 10-month mark. You can switch them over to adult food once they hit nine to 10 months old as their nutritional needs shift away from supporting rapid growth. Just make sure the transition is gradual over a week to avoid any tummy issues.
