Pitbulls are known for their fierce athletic build, short, smooth coat, and sturdy body structure.
If you own or adopt a Pitbull, you will likely need a Pitbull size chart to help monitor their growth from the early days through to adulthood.
Pitbulls are descendants of Bulldogs and Terriers.
Despite their ancestry being renowned for having aggressive traits and often being used for public entertainment, the modern-day Pitbull is tame and makes fantastic household companions.
Monitoring the Pitbull growth chart is one of the most important things their guardian should do, as it allows you to monitor their overall health and spot any issues early.
In this article, we will provide all the essential information you need to know about the Pitbull size chart.
We will take you through from birth to adulthood, so you can be clear on the size ranges and potential issues to look out for.
When Do Pitbulls Stop Growing?
Pitbulls are medium-sized dogs so tend to stop growing after one year. Some larger Pitbull varieties may pad out until 18 months of age, particularly around the chest area.
While their physical growth is complete between one year and 18 months, a Pitbull’s mental and emotional maturity won’t fully mature until two to three years of age.
There are a variety of factors that will impact your Pitbull’s growth trajectory including genetics, exercise, diet, and health issues.
Pitbull Size Chart
The Pitbull growth chart presents an estimate of the weights of your Pitbull broke down by month.
The chart also breaks down the weights by gender to give you fairly precise estimates for the growth trajectory of your Pitbull.
If you are ever concerned that your Pitbull is falling behind the weight boundaries, consult with your vet before taking any action.
Sometimes slipping slightly below or above the weight boundary is not a big issue. However, if weight loss or weight gain has come suddenly, a vet check-up is needed.
Female Pitbulls will typically weigh between 10 and 20 pounds by three months of age. This increases to 15 to 30 pounds at 6 months and then 25 to 45 pounds by one year.
Male Pitbulls meanwhile also weigh 10 to 20 pounds at 3 months but grow heavier to weigh 20 to 35 pounds at 6 months of age. By the time male Pitbulls reach one year, they will weigh between 30 and 55 pounds.

Pitbull Puppy Development Stages
Birth – 2 Weeks
During the first few weeks of life, a Pitbull puppy is completely dependent on its mother for warmth and sustenance.
Their mother’s breast milk provides essential nutrients and vitamins to kick-start their early growth.
As puppies cannot generate warmth, the mother is also needed to wrap puppies in their body heat.
You can expect a Pitbull puppy to be sleeping most of the time during these two weeks. Their eyes will slowly start to open and by two weeks they should be double their birth weight.
3 Weeks – 12 Weeks
By three weeks of age, Pitbull puppies start opening their ears and start to hear sounds. The milk teeth will also start appearing.
This growth stage sees a dramatic change from a newborn to a fully-fledged puppy. They develop physically and emotionally and will start learning good behaviors.
During this period, Pitbull puppies need to be vaccinated then you can consider socializing them to ensure they are familiar with humans and can be rehoused if that is the intention.
By seven weeks, solid foods can be introduced and you will notice the Pitbull being more vocal and engaged.
4 Months – 9 Months
Between four and nine months, the puppy Pitbull coat becomes coarser and denser, more resembling the adult coat.
Pitbull puppies will also start teething during this stage so can be safely provided with toys to chew.
Socializing your Pitbull puppy is very important during this growth stage. This process begins within the household, so you should expose your puppy to sounds, stimulating sights, hairdryers, vacuums, children, or other pets.
If you want external support, you can take your puppy to obedience classes to get the benefit of professional training. This training will also help build a bond between you and the dog.
Females will likely experience their first heat during this stage. When it does you should consider spaying them to avoid pregnancies.
10 Months – 18 Months
In this growth stage, your puppy will resemble a fully grown adult dog. While they will reach physical maturity during this stage, don’t be fooled into thinking they are adults, as they still need time to develop mental maturity.
Playing and stimulation are key in this growth stage. Pitbulls will have plenty of energy to burn so make sure to provide sufficient time to exercise. Stimulation through toys is also a great way to keep the pups busy.
As they reach adulthood, your Pitbull will reach their final height and weight.
Despite this, they will continue to pad out for up to two years as their muscles develop. During the first few years of adulthood, you will notice a transition in temperament and behavior as they transition from puppy life.
Adult Pitbulls can get involved in more intense exercises such as hiking and running over long distances.
You should continue with regular training to instill good behaviors and routines, ensuring that they become the loving, obedient dogs that many love.
How Big Do Pitbulls Get?
The final size of a Pitbull is determined by a few factors explored below.
One of the easiest ways to learn about potential growth trajectory is to ask the breeder for information on your puppy’s parents.
Most reputable breeders will have gone through a robust breeding program where lots of thought has gone into the selection of the parents.
Simply contact or visit the breeder and request they give you this information, it will give a clear indication of the final size.
A second, easy approach is to check the paws of your puppy. If the paws appear oversized to the legs and body, your puppy likely has more growth to go.
While this approach may not give specifics in terms of expected weight and height, it can be an easy monitoring tool for Pitbull owners to follow.
A DNA test can also provide genetic information on your Pitbull pup’s ancestry. It gives insights into the medical history and estimated size.
A final way to monitor the growth of a Pitbull is to use a Pitbull weight chart.
Using a growth chart is free and easy to follow. You can easily compare the measurements you generate with the expected weight boundaries.
Pitbull Growth Chart
Generally, a female Pitbull is slightly shorter and lighter than the male Pitbull. A male Pitbull weighs between 35 and 60 pounds while its female counterpart weighs around 30 to 50 pounds.
The height of a male Pitbull is around 18 to 21 inches while that of a female Pitbull is between 17 to 20 inches.

Will Neutering And Spaying My Pitbull Affect His Growth
Neutering and spaying are surgical procedures done to your dog to prevent them from breeding.
These procedures can affect the growth of your Pitbull if done at the wrong time because reproductive hormones are responsible for the growth plates.
The right time to spay or neuter your Pitbull is about the age of 6 months but you should speak to your vet to know exactly when to do the procedure.
Pitbull neutered or spayed early grow to become taller than average because the growth plates do not close hence your dog continues growing.
Additionally, the muscles of dogs that are spayed and neutered early are less and appear bulky compared to intact dogs.
Neutering is known to prevent testicular cancer, aggressive behavior, and breeding while spaying helps prevent ovarian cancer and your Pitbull from getting pregnant.
American Bully Vs Pitbull size
American Bullies tend be much stockier and sturdier compared to Pitbull’s.
The fully grown range of American Bullies is from 50 pounds to 120 pounds, while Pitbull’s range is smaller, from 30 pounds to 60 pounds on average.
Therefore, American Bullies are slightly larger on average than Pitbull’s.
The variation of weights and heights in both breeds is due to the variety and breeding program.
There are a number of quality breeding programs for these breeds, which have created pocket and large varieties.
The large, stocky head of the American Bully tends to stand out and make for a heavier overall size.
Factors That Affect Pitbull Growth
Genetics And Gender
Genetics can affect the growth of your Pitbull in many ways. If the parents of your puppy are naturally smaller than average, then your Pitbull will likely be on the smaller side and vice versa is also true.
Also, it is important to be aware of any genetic health conditions that may be passed down to your puppy by its parents.

Males are larger and will weigh between 20 and 35 pounds at the 6-month mark.
By 6 months the range of weights is fairly large, as larger Pitbull starts to break away from smaller Pitbull varieties. By this point, the effects of adolescence will have kicked in to bolster growth.
Do Pitbull Experience Growing Pain
Most dogs experience growing pains including the Pitbull.
Growing pains are also referred to as Panosteitis which causes lameness and pain in puppies.
