Standard American Bully Weight

First created in the 1990s, the Standard Bully was bred to be a show variety of the American Pit Bull Terrier, and also a companion dog.

The males are usually 17” – 20” and the females are 16” – 19” in size. They usually have a lifespan of around 10 – 14 years.

They have well-defined jaws and a muscular, thick, and solid body. Their broad chest gives them the aesthetic of great strength.

Their eyes are distant and fixed lower in the head, oval or almond-shaped, and far apart.

It’s important to note that American Bullies may have a high tolerance for pain, but this trait has the potential to work against them.

They are usually solid and fierce-looking, but less muscular and thick than the Standard Bully with well-defined jaws and a large head.

Do American Bullies Still Grow After Being Neutered & Spayed?

Neutering and spaying your American Bully can affect their growth if it is done too early, but if it is done at the right time your puppy will continue growing at a normal rate.

However, to know exactly when to do these procedures, speak to your vet about it.

There are various reasons why your American Bully should be spayed or neutered. Spaying is known to minimize the risk of uterine infections and breast cancer as well as prevent pregnancy.

How Big Will My American Bully Puppy Get?

There are different ways to predict the adult size of your American Bully. The first and most reliable way is to look at the parents.

Your American Bully is likely to take the size of their mother if they are female and generally, male dogs are slightly bigger than female dogs.

If you do not have access to the parents, your vet can help you do the DNA test and you can find more information about your puppy’s adult size based on the results.

Finally, you can check your puppy’s paws. If they are unusually large compared to the body, then they still have some time to grow so that the body and the paws are proportional.

On average, the standard American Bully weighs between 65 and 85 pounds as adults and stands at a height of around 16 to 20 inches.

Stages Of American Bully Development

American Bully Development Stages

Neonatal Period

During this stage, the puppy depends fully on the mother for feeding, cleaning, and being warm as they are entirely helpless.

This is the period between zero and 2 weeks and the puppy spends most of their time sleeping and eating. Their eyes and ears are not yet opened.

Since they are prone to worms at this stage, they should get their first worming treatment now.

Socialization Period

Between the ages of 3 and 12 weeks, your puppy is at the socialization period which is the most important stage because whatever they learn here will last throughout their life.

At this stage, your puppy learns about their environment and how to socialize with other pets and people.

This is also the time when they get their vaccinations and at 8 weeks they move to their new homes.

Juvenile Period

From 12 weeks to adolescence, your puppy is in the juvenile period. At this stage, the rate of their growth will slow down, and their sensory organs will fully develop.

You need to introduce your puppy to a training program and socialize them consistently because they have a short attention span.

Sexual Maturity Period

American Bully will reach their sexual maturity at around the age of 6 months and if they are female, they will have their first cycle of heat where they can mate.

Male dogs reach their sexual maturity earlier than female dogs. However, they are still considered puppies at this stage.

If you notice signs of aggression, disobedience, wandering, poor socialization, and plenty of behavior, then your puppy has reached the adolescent stage.

More training will help you and your puppy get through this stage smoothly.

Transition To Adult Period

American Bullies reach their adulthood at the age of 18 months when they have attained their adult weight and height. This is the time to transition them to adult food from puppy food.

The process should be done slowly over one week to give time for their stomach to get used to the new food.

At this stage, your dog needs enough exercise so that he can maintain a healthy weight to prevent them from suffering from weight-related illnesses such as obesity and diabetes.

American Bully Size Chart

The American Bully breed can be classified into four categories including Standard, Classic, Pocket, and XL.

The Standard and Classic American Bullies have the same height of between 17 to 29 inches for males and around 16 to 19 inches for females.

The shortest of them all is the Pocket American Bully with males standing at a height of around 14 to17 inches while females have a height of between 13 to 16 inches.
