The bulldog reaches his height at the shoulders around 4-5 months, usually. They will go through the long lanky stage, much like a pre teen child. But then they will start to widen. Around 9 months old, the head, chest, and shoulders start to fill out, and will do so until 3 to 4 years old. A male will have a larger head and chest area than the female will.
How long does it take for the Bulldogs head and chest to grow?
