Why is My English Bulldog’s Head Small?

Have you ever wondered why your English Bulldog’s head is so much smaller than other breeds? It’s not just a unique feature—there’s actually a scientific explanation.

In this blog post, we’ll explore the fascinating past and science behind the tiny heads of English Bulldogs. From their roots in medieval England to their current fame, we’ll uncover the surprising truth about why they have such small heads.

So if you’ve always wanted to know more about this rare breed, read on!

Normal Size for an English Bulldog’s Head

English bulldogs are known for their unique, adorable heads.

Thanks to their short snouts and flat faces, these pups usually have smaller heads than other breeds. On average, a mature English bulldog’s head is 8 inches long, 5 inches wide, and 6 inches high.

However, depending on the breeder, the size of a bulldog’s head can vary from pup to pup.

A puppy’s head will usually measure around 4 inches in length, 3 inches in width, and 4 inches in height. As they age, their skulls will grow and fill out more to give them their adult shape.

No matter what size your English bulldog’s head is, it’ll still be full of personality.

When Does an English Bulldog’s Head Grow?

The growth of an English Bulldog’s head is largely determined by genetics, but environmental factors such as diet and exercise can also affect it.

During the first year of life, a bulldog’s head will typically grow at a rate of 1/2 inch per month.

This rate slows down to 1/4 inch per month in the second year and even further to 1/8 inch per month after that. On average, English Bulldog heads reach their full size between 3 and 5 years old.

Even after reaching full size, bulldogs’ heads may still continue to grow slightly until they reach about 7 years old.

The Age at Which a Bulldog’s Head Splits

Bulldogs are known for their distinct head shape, and understanding when and why it appears is key. Most bulldogs will start to split between the ages of 4 and 6 months.

This is because their skull’s growth plates have begun to separate, giving the head an adult-like appearance. This is a normal part of a bulldog’s development and should not be a cause for concern.

It is important to monitor your bulldog’s health during this time and make sure they are eating properly. If you notice any unusual behavior or changes in your bulldog’s head shape, contact your veterinarian right away.

Knowing when a bulldog’s head splits can help you prepare for their health and growth needs, so keep an eye on your puppy as they grow.

Why Do Bulldogs Have Short Faces?

Bulldogs are instantly recognizable for their short faces and wide, round heads.

But why do they have this particular look? The answer lies in their genetic makeup. Bulldogs have a combination of brachycephalic (short-faced) and mesocephalic (medium-faced) traits, which is why they have the short faces we know and love.

This allows them to breathe more easily and helps regulate their body temperature better.

But that’s not all—the breed was also selectively bred to have a wide head so that it could fit into smaller spaces, such as the tight corners of bullfighting rings. Bulldogs also have a unique jaw structure that gives them their characteristic “underbite” look.

This jaw structure helps them hold onto things better, making them excellent at tasks such as herding sheep or cattle.

At What Age Do Bulldogs Fill Out?

You may be wondering when your pup will reach its full size and muscle mass.

The answer is that English Bulldogs typically fill out between the ages of 18 months and 2 years old.

During this time, their heads become fuller and rounder, and their wrinkles become deeper. While their head size may not increase, it will become more filled out due to the growth of muscle mass in the face and neck region.

It’s important to keep in mind that some Bulldogs may take longer than others to fill out, so patience is key.

To ensure your Bulldog fills out properly, feed them a balanced diet with plenty of exercise. This will help keep them healthy and happy as they reach their full potential.

Common Health Concerns Related to Small Heads

English Bulldogs are an adorable breed of dog, but their small heads can cause some serious health problems. Owners need to be aware of the risks associated with their bulldog’s head size, from respiratory issues to eye and dental problems.

Brachycephalic Airway Syndrome (BAS) is a common problem for bulldogs due to their airways being too small and constricted.

This can lead to difficulty breathing, snoring, and even choking. Dry eyes and painful corneal ulcers can also occur as a result of shallow eye sockets.

Dental problems are also common in bulldogs due to their short muzzles and overcrowded teeth. Periodontal disease, gum recession, and tooth decay are all potential issues that owners should watch out for.

It is essential for owners of English Bulldogs with small heads to be aware of these health concerns so they can take steps to prevent them or catch them early if they do occur.

Regular veterinary visits are key for early detection and treatment of any potential health issues related to the bulldog’s head size – ensuring your English Bulldog lives a long, happy life.

Diet and Exercise Tips to Promote Healthy Growth in Bulldogs

Whether you’re a first-time Bulldog owner or an experienced one, it’s important to know the right diet and exercise tips for your pup. Here are eight essential things to keep in mind when caring for your Bulldog.


The English Bulldog should be fed a high-quality diet that is specifically formulated for their breed. This should include proteins, carbohydrates, fats, vitamins, minerals, and other essential nutrients. Feeding them a diet with too much fat can lead to obesity, which can impede their growth.


Regular exercise is important for English Bulldogs to maintain a healthy weight and promote muscle growth. Exercise should include daily walks and playtime. Swimming can also be beneficial for English Bulldogs as it helps build muscle strength without putting too much strain on their joints.


Adding supplements to your Bulldog’s diet can help promote healthy growth and development. Omega-3 fatty acids are essential for maintaining healthy skin and coat, while glucosamine can help with joint health. Probiotics can help support the immune system, while vitamins A, D, E, and B complex can help with overall health.


Regular grooming is essential for keeping your Bulldog’s coat healthy and promoting skin health. Brushing helps remove dead hair and dander, while bathing helps keep the coat clean and free of dirt or debris. Nail trimming should also be done regularly to prevent overgrowth or splitting of the nails, which can cause pain or discomfort in bulldogs.


To stay hydrated, make sure your English Bulldog has access to plenty of fresh water throughout the day. Dogs need water just like humans do, so make sure they have access to lots of fresh drinking water at all times.


If you have any concerns about your dog’s growth or development, it’s always best to consult with your vet, who will be able to give you tips on how to care for your pup properly.

How Do You Know If Your Dog’s Head Is Smaller Than Average?

Take a look at the size of the muzzle and skull in comparison to other dogs of its breed.

Another way to determine your puppy’s head size is with a flexible measuring tape. Measure the circumference of your dog’s head from its eyes to the back of its neck and compare it to others’.

Don’t forget to pay attention to shape as well as size; it should be more rounded than rectangular or flat. And note any differences between your pup and others, such as an unusually short muzzle or wide forehead – these may point towards a smaller than normal head size for your puppy.
