When Is A Staffordshire Bull Terrier Fully Grown?

The growth of your puppy can be influenced by diet, genetics, physical activity, and health.

Staffordshire Bull Terriers are fully grown when their growth plates are completely closed, and new tissue is no longer being produced. This happens between the ages of 12 and 18 months.

However, they will continue to grow bulkier and wider until the ages of 2 or 3 years old. This is when they achieve their mental growth and are now considered fully mature.

Providing a balanced diet and daily required exercise will ensure that your puppy reaches their optimal growth.

Staffordshire Bull Terrier Growth Chart – What to Expect

Staffordshire Bull Terrier Cost

The following is what you should expect from a Staffordshire Bull Terrier Growth Chart:

Birth – 2 Weeks

During this stage, the puppy is completely dependent on the mother for care and food. Since the puppy cannot regulate their body temperature, their mother is providing them with warmth. At this point, they are blind, deaf, and only do a slow crawl.

At this stage of growth, sleep is important for your puppy because most of their energy is used in developing and growing.

3 Weeks – 12 Weeks

During the third week, the puppy begins to open their ears and eyes to sounds and new sights. They start making short grunts which lead to barking and whining. At this age, they can control their bowel movements and bladder. Their first teeth come in as well.

The puppy learns submissive behaviors, bite inhibitions, overall confidence, and attention from their mother and siblings. At 6 weeks, the puppy can be fully weaned and at 8 weeks they can move to their new home.

This is the right period to socialize your puppy and introduce them to other people and dogs. You can introduce potty training and other in-house training such as walking on a leash.

4 Months – 9 Months 

This is a learning period for your puppy and even though they have a lot of energy, you should not over exercise them beyond their limit as their joints and bones can be affected.

This is the stage to provide your puppy with lots of stimulation and toys so that they can stay occupied without feeling idle.

Staffordshire Bull Terrier Development

Ensure that your puppy is vaccinated and trained at this age. Your puppy will start showing dominance in the house and will want to be the leader. Speak to your vet about spaying or neutering your puppy at around the age of 6 months.

10 Months – 18 Months

This is the period where your puppy reaches their physical maturity. At this stage, your puppy is now an adult, and they should be fed adult dog food. Your dog has an adult mindset but still needs plenty of mental stimulation and physical exercise.

Continue socializing and training your dog to ensure that they develop a healthy relationship with you and other family members.


As an adult, your dog is fully mentally and physically mature. All they need at this stage is your attention and care. They need to be fed a healthy diet and given the exercise they need.

You should also take them to the vet regularly for medical examinations to ensure that they are healthy and happy.

How Big Do Staffordshire Bull Terriers Get?

One of the concerns you may have as a Staffordshire Bull Terrier owner is how big they will get. There are ways in which you can predict the adult size of your puppy, they include parents, paws, and DNA tests.

Meeting the parents of your puppy and looking at their size will give you a clear indication of the size of your puppy when they are adults. If your puppy is female, they will take the size of their mother and if they are male, they will be slightly bigger.

Your puppy’s paws can tell you a lot about their adult size. Puppies with tiny paws may grow to be medium-sized dogs but will likely be small and puppies with bigger paw sizes will be large dogs.

Doing a DNA test for your puppy is also another way of knowing their adult size as the tests will show their lineage and the size of the relatives.

On average, an adult male Staffordshire Bull Terrier weighs between 25 and 38 pounds and has a height of 14 and 16 inches.

On the other hand, their female counterparts weigh between 23 and 35 inches with a height of 13 and 15 inches.

Will Neutering/Spaying My Staffordshire Bull Terrier Affect His Growth?

Spaying and neutering involve the removal of ovaries and testes, respectively through surgery. When done at the right time, that is between the ages of 6 and 9 months, the growth of your puppy should not be affected.

Spaying and neutering have several health and behavioral benefits including lowering the risk of cancers related to reproductive organs, preventing uterine infections, reducing aggressive behaviors, and preventing breeding.

However, spaying and neutering increase the risk of obesity, hypothyroidism, and when done early they can cause hip dysplasia, bone cancer, and torn ligaments.

Staffordshire Bull Terrier Height Chart

Knowing your Staffy’s height is important because you will use the measurement to buy them certain items such as winter gate, dog gate, and belts. You will need a measuring tape to determine your puppy’s height at home.

To measure your puppy’s height, let them stand straight and ensure they are not shrinking to the earth. Find the withers, the point in which the shoulders and the neckline link up.

Measure from the ground to the withers, and that is your puppy’s height.

Generally, the height of female Staffordshire Bull Terrier is between 13 and 15 inches while their male counterparts stand at 14 to 16 inches tall.

American Staffordshire Terrier vs Staffordshire Bull Terrier Size

The Staffordshire Bull Terrier and the American Staffordshire Terrier are two dogs that are frequently confused because they look similar.

However, there is a difference in their size because the American Staffordshire Terrier is heavier and taller than the Staffordshire Bull Terrier.

The American Staffordshire Terrier weighs between 45 and 70 pounds and stands at a height of around 17 to 19 inches.

On the other hand, the Staffordshire Bull Terrier weighs between 23 to 38 pounds and has a height of between 13 and 16 inches.

Factors That Affect Staffordshire Bull Terrier Growth 

The following factors can affect the growth of your Staffordshire Bull Terrier puppy:

Genetics & Gender

Puppies inherit 50% of their genes from the mother and 50% from the father. This means that genetics play a key role in the growth of a Staffordshire Bull Terrier. If the parents are small, the puppy will be small when they are fully grown and vice versa.

Gender is another factor that affects growth in puppies. Typically, female Staffordshire Bull Terriers are lighter and smaller than male Staffordshire Bull Terriers.


The type of diet you are giving your puppy will influence their weight. A Staffordshire Bull Terrier should be fed well-balanced food, whether homemade or bought in stores.

You should seek advice from your vet when it comes to the food your puppy needs to stay healthy and active.

You can give your puppy treats when training them but too much of it can lead to obesity. Ensure that you understand which foods are healthy and safe for your puppy and which ones are not.

Physical Activity & Health

Regular exercise will help your Staffordshire Bull Terrier stay physically and mentally fit. Exercises such as jogging, long hikes, and playing catch in the backyard are great for keeping your puppy in the right physical condition.

Staffies cannot tolerate heat, therefore, avoid over-exercising them in humid or warm weather.

Since Staffies are predisposed to certain conditions such as cataracts, hip dysplasia, PHPV, and L-2HGA, it is important that you take them to the vet for tests as early as 4 weeks old.

This will ensure that proper treatment is administered and that you are informed of potential health problems in your puppy in the future.

What If My Staffordshire Bull Terrier Is Not the Right Weight?

If your Staffordshire Bull Terrier puppy is overweight or underweight, take them to the vet for a medical exam. This will rule out any underlying conditions that may be causing your puppy to gain or lose weight.

Once your puppy is cleared of any illness, you can help them gain or lose weight at home.

To help your puppy gain weight, increase the amount of food you are giving them and add supplements to their diet with guidance from the vet.

On the other hand, if your Staffy is overweight, feeding them fewer calories and introducing certain exercises such as jogging, walking, and swimming will help them lose weight. You can also give them healthy treats that are low in calories such as baby carrots and green beans.

How Much Does It Cost to Own a Staffordshire Bull Terrier?

Owning a dog should not cause a financial burden to you and your family. Therefore, knowing how much a Staffordshire Bull Terrier costs will help you to budget and be prepared for all the potential expenses you will incur.

The cost of a Staffordshire Bull Terrier is between $975 and $2500, which averages at $2000.

The price is influenced by factors such as the breeder’s reputation, location, and the puppy’s bloodline. Expect your puppy’s expenses in the first year to be around $4,455 and after that, you will spend about $1315 per year.

These costs cover essential expenses such as training, supplies, food, treats, medical care, grooming items, microchip, and licenses.

There are other optional costs that you can incur throughout the life of your puppy such as spaying or neutering, pet insurance, pet walking, and pet sitting.

Staffordshire Bull Terrier Genetics and Common Health Problems

Like other dogs, Staffordshire Bull Terriers can develop certain health conditions. The following are the main issues to watch out for if you own a Staffy:

Hip Dysplasia – this is a condition that affects the hip joints of your Staffy where the socket and ball joint do not align well.

This causes rubbing and grinding inside the joint, and over time it leads to impaired movement and even permanent damage. The best way to prevent this condition is to avoid subjecting your Staffy to heavy exercises.

Cataracts – if both parents carry the gene responsible for this condition, there is a high chance that puppies will be born with it.

Cataracts manifest itself when your puppy is around 8 weeks old and if not treated early it can cause blindness within 2 to 4 years.

Follicular Dysplasia – this condition causes abnormalities in your puppy’s hair structure. Staffies are likely to get the seasonal variation of this health problem where the hair appears thinner than usual in some seasons.

Persistent Hyperplastic Primary Vitreous (PHPV) – this is another eye condition that affects Staffordshire Bull Terriers.

Screening for this condition when your puppy is four weeks old is the best thing to do and your vet will administer the right treatment for it.

L-2 Hydroxy glutaric Aciduria (L-2HGA) – this condition affects the nervous system of your Staffordshire Bull Terrier and causes tremors, seizures, and muscle stiffness when your puppy is involved in activities that stimulate and excite them.

Final Words

Understanding the factors that affect your puppy as they grow such as genetics, diet, gender, nutrition, health, and physical activity will prepare you to provide them with the care and support they need.

Regular visits to the vet are also essential in ensuring that your puppy is in good health and is the right weight for their age.
