When do Maltese stop growing?

Maltese stop growing around 12 months of age, although they might continue filling out and developing muscle mass until they’re 18 months to 2 years old. While their growth in terms of height stabilizes relatively early, their physical and behavioral development continues for a bit longer. Proper nutrition, regular exercise, and attention to their specific health needs during this growth phase are essential to ensure they become healthy and well-proportioned adults.
