When do Shiba Inus stop growing?

Shiba Inus stop growing at around 12 months old. However, they may continue to fill out and develop muscle mass and weight until they are approximately 18 to 24 months old. 

Individual growth patterns can vary, and genetics play a significant role in a Shiba Inu’s size and development. Proper nutrition, exercise, and regular veterinary care during their growth stages are essential to ensure they reach their full potential and maintain good health.
