When do Maltese stop growing? 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.
