Bull Terriers are known for their distinct appearance and playful personalities, making them a favorite among dog enthusiasts. With their egg-shaped heads and muscular builds, Bull Terriers were originally bred as fighting dogs in the 19th century but have since become loyal family pets. They are energetic and intelligent and require a good amount of exercise and mental stimulation. As a pet owner, tracking their growth is crucial to ensure they are developing healthily and at the correct pace.

In this guide, we will explore the growth stages of Bull Terriers and provide insight into how large they are likely to get. We'll examine growth charts for male and female Bull Terriers, give you a sense of when they stop growing, answer common questions like how much to feed a puppy , and offer tips on how to ensure they remain healthy.

Your new puppy may be small — but their vet bills won't be.

Save big on costs with pet insurance, so you can protect your puppy while protecting your wallet.

Adult male Bull Terriers typically weigh between 70-85 lbs and stand about 21-22 inches tall at the shoulder.

Female Bull Terriers usually reach their full height between 12 and 18 months. Most females weigh between 60-80 lbs and stand 19-21 inches tall as adults. Though they may stop growing in height around one year old, muscle development can continue until they are closer to two years old.

When Do Bull Terriers Stop Growing?

Bull Terriers, like many medium-sized breeds, typically stop growing in height by the time they are about 12 to 14 months old. However, while their height may stabilize, they often continue to gain muscle and body mass until they are closer to 18 to 24 months old.

For both male and female Bull Terriers, the most rapid growth occurs in the first six months. During this period, you'll notice significant changes in their size, weight, and behavior. By the time they reach one year, they are close to their full height, but you may notice continued filling out as their muscles develop.

Owners should keep an eye on their dog's weight during this period to ensure they are gaining at a healthy rate and not becoming overweight.

How Much Bigger Will My Bull Terrier Get?

Bull Terriers tend to reach their adult height between 12 and 14 months, but muscle development continues well into the second year. Therefore, even if your Bull Terrier seems to have reached their full size at one year old, they may still gain muscle and bulk.

To estimate how much bigger your Bull Terrier will get, you can use our puppy weight calculator or refer to their current weight as a guide. At six months, most Bull Terriers are approximately two-thirds of their adult weight. For example, if your six-month-old Bull Terrier weighs around 45 lbs, they will likely weigh about 70-80 lbs when fully grown.

What is the Size of a Full-Grown Bull Terrier?

An adult Bull Terrier is a medium-sized dog with a muscular build. Males typically weigh between 70-85 lbs and stand around 21-22 inches tall, while females weigh between 60-80 lbs and stand around 19-21 inches tall.

Their muscular frame, combined with their broad chest and strong legs, make them one of the most powerful breeds for their size. They have a compact yet strong body built for both agility and endurance

How Do I Make Sure My Bull Terrier is Healthy?

Every pet owner has a part to play in ensuring their dogs grow and stay healthy. Here are some helpful tips to keep your Bull Terrier in the best condition.

Observe Diet

The kind of foods you offer your dog will determine its growth rate and overall health. Choose high-quality foods, rich in all nutrients, including fats, proteins, and vitamins. Also, opt for foods meant for medium-sized dogs and check their energy levels.

Note that as much as you want to see your dog grow fast, overfeeding poses health risks such as obesity. So, feed your Bull Terrier moderately and keep track of its weight gain and fat accumulation. We suggest checking the measurements contained on their dog food label or asking the vet how many cups to feed them.

Regular Workouts

Bull Terriers are known for their energetic build; you cannot afford to keep the dog idle even for a day. Create time to take your dog for a walk or involve it in games that challenge the pet's physical and mental skills. Otherwise, your dog will be subjected to boredom, which can lead to destructive behaviors. Not to forget that a sedentary lifestyle increases the risk of unhealthy weight gain.

Monitor Their Growth

Keep a close eye on your Bull Terrier's growth by regularly weighing them and measuring their height. This can help you ensure they are growing at a healthy rate. If you notice any unusual changes or signs of stunted growth, consult your vet.

Regular Checkups

Invest in routine vet visits to monitor your Bull Terrier's health. The visitations are a perfect chance for vaccinations, tick and flea treatments, and dental checkups. Annual health examinations are recommended to identify and treat any underlying issues before they escalate. 

Before any vet visits, we recommend purchasing Bull Terrier pet insurance, so you’re equipped with financial support for unexpected vet bills caused by common health issues in dogs.

Injuries or illnesses often require expensive medical treatments, but with pet insurance, you can get reimbursed for a portion of the expenses you might incur for veterinary care related to covered conditions. You can also choose add-on wellness plans to help with vet visit costs related to routine care, including flea/tick prevention, spaying or neutering, and more.

Key Takeaways

Bull Terriers are strong, energetic, and loyal dogs that require careful attention during their growth stages. Understanding their growth patterns and regularly monitoring their development will help you ensure they reach their full potential as healthy adults.

Whether male or female, Bull Terriers need proper nutrition, regular exercise, and a lot of love and attention to thrive. By tracking their growth and taking steps to ensure they remain healthy, you'll set your Bull Terrier up for a long and happy life.

Some people can predict the future. For everyone else, there's pet insurance.
