Bulldog growth stages

When does a bulldog's head split? Bulldog Head Growth Stages Explained - Bulldogcorner (2)

Bulldogs grow in the following stages:

0-4 weeks - Newborn Bulldogs

Newborn bulldogs sleep and eat. This is basically what they do most of the day.

A healthy newborn bulldog will weigh around 5 ounces for males and 4 ounces for females, and they will spend these first few weeks with their eyes closed and unresponsive to new sounds. They will begin to grow rapidly in size and weight after birth, provided they are fed properly.

Within a few weeks, their eyes will open, they will make small, weak squeaks, and begin trying to communicate with this new world they find themselves in. Soon they will start to move.

4-8 Weeks – Bulldog Babies

Your Bulldog at this stage will start to move around and try to explore the world. they will try to move further and further away from the safety of their mother, but they are not ready to be separated from their parents just yet.

At this stage, they still depend on mother's milk for food, but the mother will start to wean them. The transition from milk to solid food starts at this stage, so you can start feeding them puppy food before they are fully weaned.

At this stage they will look like a miniature bulldog as they will still lack their muscular build but will have their trademark wide stance appearance. At this stage they should also start to develop social skills, so it's ideal to leave them in their litters, as they will learn a lot from their siblings and parents.

9-12 weeks: early pup

Your Bulldog puppy will start to develop muscles, a sense of independence and a little bit of mischief too. They will move further away from their parents, urinate on the floor a lot, and run around a lot.

This is the time to start training them. Potty training is obviously crucial at this stage, as is leash training. You can also start taking them outside to show them the world and help them develop more leg muscles. Socialization will also make them more stable and less nervous.

3-6 Months – Dog

They are building muscle, getting to know the world and starting to question their place in it. This means that dominant traits start to appear and become a littleheadstrongas they try to figure out who is the leader or "alpha" of the house.

That's when you start teaching them about boundaries. You have to be patient and dogged at this stage to show them that you are in charge, not them. Setting clear boundaries at this stage is critical to their development and can make a big difference in their training for the rest of their lives.

6-18 meses - Bulldogs Teenage

At this stage, their bodies grew to normal size, butemotionally, they are somewhere between puppies and adults, which is why I call them Teenage Bulldogs at this point.

More socialization and training can help stabilize their personalities here, and teaching them tricks will keep them mentally sharp and help them develop new skills.

From now on, training and socialization should be ongoing things that you will be doing for your dog for the rest of their beautiful lives.
