At what age is a setter fully grown?

Setter breeds, such as the English Setter or Irish Setter, typically reach their full growth by around 18 to 24 months of age. However, while they may achieve their adult height within this timeframe, they may continue to fill out and develop muscle tone until they are about 2 to 3 years old. Individual growth can vary based on genetics, diet, and overall health. Regular veterinary check-ups can help monitor their growth and development.
