When Does a Pitbull Stop Growing? Facts & FAQ

As a Pitbull owner or someone considering adding one to your family, you might be curious about when these lovable canines will reach their full size. A Pitbull can reach full size in around 12-18 months. Knowing when they stop growing and how to support their healthy development is essential for any responsible pet parent.

We invite you to join us as we explore that very topic. You’ll also pick up some helpful tips to ensure you’re raising a healthy, happy pup. Let’s jump right in!


The Growth Timeline of a Pitbull

Pitbulls, like all dogs, grow at different rates depending on their genetics and environment. Generally, you can expect your Pit to reach its full size between 12 to 18 months of age.1 However, muscle development and weight gain can continue until they’re around two years old.

So, while their height may plateau sooner, they’ll still be filling out and gaining strength for a little longer. And with regular exercise and care, you can look forward to your pup having a healthy weight and build.

How Much Should a 1-Year-Old Pitbull Weigh?

At around one year of age, your Pitbull is likely nearing the end of its vertical growth spurt. But what should they weigh? This is a great question because it helps you ensure your pup is on track and healthy.

Males typically weigh between 35 to 50 pounds, while females range from 40 to 50 pounds. Keep in mind that these figures are approximate,2 as each dog is unique. If you’re concerned about your Pitbull’s weight, consult your veterinarian for guidance.

How Big Can Pitbulls Get?

Pitbulls are a medium to large-sized breed, and their size can vary depending on their specific type and genetics. American Pitbull Terriers, for example, usually stand between 17 to 21 inches tall at the shoulder.3 Some males can weigh up to 80 pounds, while females top out around 65 pounds.

If you have a different type of Pitbull, such as an American Bully or a Staffordshire Bull Terrier, their size may vary. It’s always best to research the specific breed or consult with a knowledgeable professional if you’re unsure.

Promoting Healthy Growth for Your Pitbull

As a responsible pet owner, you want to ensure your Pitbull grows to be strong and healthy. Here are a few tips to help you achieve that goal:

Balanced Nutrition

It’s crucial that you feed your pup quality food. That means making sure it’s right for their age and that it meets their nutritional needs. Remember to adjust portion sizes as your dog grows, and don’t hesitate to check with your vet for specific recommendations.

Regular Exercise

Pitbulls require ample daily physical activity due to their high energy levels. Be sure to incorporate activities like walking, hiking, or playing fetch to help them burn off that energy and maintain a healthy weight.

Mental Stimulation

Keep your Pitbull mentally engaged with toys, obedience training, or even agility courses. Pitbulls get bored easily and can quickly become destructive if they are reigned in. Take the time to instill discipline while making sure they have lots to keep them busy.

Vet Check-ups

Regular visits to the vet are critical components for keeping your Pitbull healthy. Your vet can help identify any potential issues early on, ensuring your dog stays on track developmentally and receives any necessary treatment.


As early as possible, you need to make sure your Pitbull spends plenty of time around different people, pets and animals, and places. In doing so, your Pittie will be far less likely to act aggressively or afraid around others.

If you’re too busy to take your pup for a walk every day or give them the exercise needed for healthy growth, consider hiring someone to do these things for you. Starting a routine early on will go a long way, ensuring a happy and healthy companion.

Keeping Your Pitbull Safe and Happy

As your Pitbull grows, it’s crucial to keep them safe and content. Here are some tips to help:

Leash Training: Teach your pup proper leash manners from a young age to prevent pulling or lunging. This not only keeps them safe during walks but also makes the experience more enjoyable for both of you.

Crate Training: A crate can be a safe and comfortable space for your Pitbull, especially during their growing stages. Proper crate training can help with housebreaking, reduce separation anxiety, and provide a cozy spot for your pup to retreat when they need some downtime.

Positive Reinforcement: Use positive reinforcement techniques, such as treats, praise, and playtime, to reward good behavior. This helps build a strong bond between you and your Pitbull while also teaching them desirable habits.

Preventing Escapes: Pitbulls can be quite curious and adventurous, so ensure your yard is securely fenced and your dog can’t easily escape. Regularly check for gaps, broken panels, or any other potential escape routes.

Provide Comfy Spaces: As your pup grows, make sure they have a comfortable bed or resting area that can accommodate their size. This helps prevent joint issues and ensures they get the rest they need to support their growth.

Making these vital tips a regular part of your Pit’s upbringing will have a positive effect not just on their health but also their mental well-being. Your Pitbull will most definitely appreciate the love and care as they grow.



Understanding when your Pitbull will stop growing and how to promote their healthy development can be incredibly rewarding. By following the tips and advice provided in this article, you’ll be well on your way to raising a strong, happy, and well-adjusted Pitbull companion.

Remember, each dog is unique, and it’s essential to monitor your pup’s progress and consult with your veterinarian for personalized guidance. Happy pet parenting!
