When Do Staffordshire Bull Terriers Stop Growing?

When you look at your American Staffordshire Terrier puppy, you might wonder, “When will this puppy stop growing?” It is a typical issue because there is so much misinformation about this breed out there.

In general, your American Staffordshire Terrier puppy will stop developing between the ages of 12 and 18 months.

The majority of puppies reach their full height by their first birthday, but they will continue to acquire weight until they are about 18 months old.

In some situations, a dog may stop growing a little sooner, but with this breed, you can be certain that the dogs will not grow any larger by 18 months.

What is the Standard Staffordshire Bull Terrier Size

A Staffordshire Bull Terrier’s average weight varies between males and females. A male Staffordshire Bull Terrier weighs between 24.25 and 37.48 pounds (13 to 17 kilograms). A female Staffordshire Bull Terrier weighs between 22.05 and 35.27 pounds (11 to 15.4 kg).

How To Weigh Your Staffordshire Bull Terrier Puppy?

If you want to maintain track of your Staffordshire Bull Terrier’s weight, you must first learn how to weigh him properly.

To begin, you should be able to weigh your Staffordshire Bull Terrier at home if he is a puppy or if you are just large enough to hold him. This can be accomplished with a standard bathroom scale.

To begin, weigh yourself and record the result. Then, while standing on the scale, pick up your dog and hold him. The difference in weight represents your dog’s weight.

If your dog is too huge to carry, you can either invest in a dog scale, which can cost upwards of $100, or contact your veterinarian. The majority of veterinarian offices will enable you to use their scale.

Unless there is a health problem, you can weigh an adult Staffordshire Bull Terrier once every six months. Once a week is sufficient for a puppy to ensure he is growing normally.

What Is A Staffordshire Bull Terrier’s Neck Size?

To determine the neck size of your dog, use a soft and flexible tape measure to determine the neck size of your dog where her collar naturally falls. Then, put two fingers between your dog’s neck and the tape measure to ensure that the dog collar fits snugly but comfortably. The Staffordshire Bull Terrier’s average neck circumference is between 14 and 20 inches.

Factors That Affect Staffordshire Bull Terrier Puppy Growth 


There are a few elements that influence the size of a Staffordshire Bull Terrier puppy.

The first is related to genetics. You can get a fair idea of your puppy’s final size by looking at his parents.

While males of this breed are slightly larger, the size difference is minor and should not be considered when determining your puppy’s growth.

Diet & Nutrition

When it comes to a developing puppy, nutrition is crucial. You want to ensure that your dog lives a long and healthy life.

Your dog’s growth will not be hampered by poor nutrition, but it may cause joint problems. If you overfeed your dog, for example, his expanding joints and bones will be overburdened.

Make sure your dog is eating a well-balanced and nutritious diet. Examine the ingredients in your dog’s food to determine what you’re feeding him.

Physical Activity & Health

Physical activity is an excellent strategy to avoid your dog from becoming overweight and causing damage to his growing bones.

Over-exercising young puppies, on the other hand, might be harmful to their developing bodies. Similarly, keeping your dog healthy will ensure that his body grows up to be as powerful as you want it to be, on the inside and out.

Take your dog for regular walks and keep your vet appointments.

Will neutering/spaying my Staffordshire Bull Terrier have an impact on his growth?

It is critical to have your dog spayed or neutered. This is done to keep your dog healthy and to avoid unintended pregnancies.

However, there is widespread concern about how spaying or neutering a dog would affect his growth.

While spaying or neutering a puppy has no effect on his final size, it can have an effect on his growth in other ways. When hormones are removed, the puppy’s joints do not expand properly, resulting in mobility difficulties as they get older.

As a result, it is best to wait until your American Staffordshire Terrier has finished growing. If your dog is escaping and placing himself in danger, it may be best to do it sooner rather than later.

How Much Does It Cost To Own A Staffordshire Bull Terrier?

In the United States, the average price for a Staffordshire Bull Terrier is $2000. Staffies are priced between $1000 and $3000. It varies depending on the breeder’s reputation, region, pedigree, age, and gender of the dog. If a Staffordshire Bull Terrier is scarce in your area, the price may be slightly higher.

How To Help Your Staffordshire Bull Terrier Lose Weight If He Is Overweight 

As with humans, exercise is critical for your overweight dog’s health. Increased movement helps your dog burn off excess energy (and calories consumed). Avoid panic! Exercising your pet does not have to include marathons or lengthy hikes. Regular walks and the opportunity to run and play safely off-leash. 

Even creating a stimulating indoor environment that encourages your dog to exercise on a regular basis can help. Bear in mind that different breeds require varying amounts of exercise, so visit your veterinarian, breeder, or your dog’s breed standard for recommendations on recommended activity levels.

Distinguish Begging from Hunger

Begging is not necessarily motivated by a desire for more food; it is also used to gain attention. (And, by rewarding the behavior, you reinforce and encourage it to continue.) If your dog begs, do not automatically assume he is hungry. Trust your instincts and keep track of the date and time of your last meal. 

If your dog is prone to begging and you are prone to succumb to those puppy dog eyes, choose a high-protein meal with a fiber blend to help control your dog’s hunger and voluntary food consumption. In this manner, you may feed your dog with the assurance that he will feel fuller and content for a longer period of time.

Restriction on treats and table scraps

Dog treats
Dog treats

Even when our dogs are not begging, many of us provide an excessive amount of treats and table scraps. Dogs are not required to share our food! Consider treats and scraps for your pet in the same way that you would candy for children to help you keep them in check. If you’re going to utilize snacks for training, choose low-calorie, low-fat ones and keep the portions small. 

As an alternative, keep in mind that clickers are excellent for reinforcement… and they have no calories! After all, a few extra pounds can make a significant impact on the lives of dogs, which are significantly smaller than humans. (Even the colossal breeds!) Therefore, focus on a balanced diet and resist the temptation to “reward” them with extra.

Customize Your Dog’s Diet

Not all weight-loss foods are created equal, which is why it’s critical to match your dog’s nutrition plan to their unique needs. Choose a brand that caters to your dog’s unique needs, whether they be weight control, dietary sensitivities, or illnesses.

Knowing what to expect from your developing Staffordshire Bull Terrier puppy is essential for ensuring that your dog not only has a loving home but also a long and healthy life ahead of him.

If you are concerned that your puppy is not growing properly, the best thing you can do is take him to the vet. Your veterinarian will either be able to put your mind at ease or offer you the necessary information to get your pooch back on track.
