When does a Chartreux stop growing?

A Chartreux stops growing around three to four years old. This slow-to-mature breed typically reaches their full height by one year of age, but males can continue to fill out and gain weight until their fourth birthday, while females reach their full size around three years old.

Factors that can affect their growth include genetics, which play a significant role in determining their ultimate size and development rate; diet, as a balanced and nutrient-rich diet supports healthy growth, while poor nutrition can stunt their development; and regular veterinary care, which ensures that any health issues are identified and managed promptly. Additionally, providing a safe, supportive, and enriching environment can support healthy development.
