When Does a Pitbull Puppy Stop Growing?

Pitbull puppies, like all dog breeds, start tiny and then grow into full-size dogs. (Circle of life and all that.) While they aren’t the biggest dog breed by any means, Pitbulls can get relatively large once they’ve reached their maximum size, especially males.

The other day I was asked a question about Pitbulls and their growth patterns, which are similar to other dogs and have (some) similarities to humans. That got me thinking about a question I hear pretty frequently, namely, “when does a pitbull puppy stop growing?”

The answer is that a pitbull puppy stops growing after about 2 to 3 years, although the vast majority of their noticeable growth is during year #1. After that, they will still grow and “fill out,” but it won’t be nearly as pronounced. 

Now that you know it takes between 2 and 3 years for a pitbull puppy to stop growing, it’s likely you have other questions about your new pitbull fur baby. When do they stop teething, for example, and what’s the average weight of a fully-grown pitbull? If you do, read on. I’ve got the answer to those questions and several more below. 

Can You Tell How Big a Pit Bull Puppy Will Get?

Here’s a fact; determining the exact size and weight your Pit Bull puppy will reach is extremely difficult. Like humans and many other types of mammals, a dog’s growth depends on several factors, many of which are difficult to determine.

Knowing the size of the dam (mother dog) and the sire (father dog) can be very helpful when trying to determine what your Pit Bull puppy’s size and weight will be, no doubt, but it’s still an inexact science.

Some dog experts will tell you that you can look at the size of your Pit Bull puppy’s feet to determine how big they will get, but that’s not an exact science either. In a pinch, however, you can tell by using the following two (very unscientific) methods:

1) If your Pit Bull puppy’s feet look too big for their body, they still have more growing to do. If they look “right,” it’s likely that they’ve either stopped growing or won’t grow much more. 

2) Since Pit Bulls are medium-sized breeds, you can take their weight at 14 weeks, multiply it by two and add another half of their weight above that. The number you get is the approximate weight they will be as an adult. 

The formula looks like this: (Weight at 14 weeks X2) + (½ their weight at 14 weeks) = Adult Weight. So, if they weigh 15 pounds at week 14, their adult weight will be 37.5 pounds. (15 x 2) + (15 ÷ 2) = 30 + 7.5 = 37.5.

What Age do Pitbull Puppies Grow the Most? 

Typically a pitbull puppy will grow the most during its first year of life. More specifically, between the 4th month and 8th month, which is when they develop the fastest. Between the day they’re born, and 4 months, pitbull pups usually grow rather slowly while many parts of their body are maturing rapidly inside them.

After eight months of age, your pitbull puppy will still be a puppy and still keep growing, but their growth will slow down considerably. Typically they will reach about 80/90% of their adult weight at this point, although all pitbull pups are slightly different and grow at different rates.

When Does a Pit Bull Puppy Stop Teething? 

One question I hear all the time (usually from pitbull puppy owners at the end of their leash) is, “when does a pitbull puppy stop teething?!”  The truth is, teething is a phase that all dogs go through, and pitbull pups are no different.

For Pitbulls, the usual age at which they stop teething is between 4 to 8 months, although some go on for a while after this time also. One bit of good news is that Pitbulls, like most dogs, go through their teething phase relatively fast and much faster than a human child. (With less crying and fussing, too, although more tearing, chewing, and destroying stuff).

Keep in mind that a pit bull pup will chew on practically anything when they’re teething. That includes everything they can get their mouth on, from shoes to pillows, furniture, and anything else they might find lying around your home. For that reason, during their teething phase, it’s best to keep your prized possessions far from their growing choppers.

What is the Average Weight of Pit Bulls?

The average weight of a Pit Bull depends on the type of pitbull they are and whether they’re a male or female. Keep in mind that Pitbulls are built to be bigger, more muscular dogs than many other dog breeds. (If you’re looking for a small dog, you probably don’t want to get a pit bull.)

That being said, there is quite a bit of variety in the pit bull breed, which means you can see a rather significant difference between Pitbulls in terms of their overall size and weight and still have a pitbull that is the correct size. 

For example, bigger pitbull breeds can reach upwards of 80 and even 90 pounds and be perfectly normal and have a healthy weight. Other pitbull breeds can max out at about 40 pounds, or roughly half the size, and still be considered within the normal range.

Depending on the type of pitbull you have, though, the numbers below should give you an idea about their average size from birth to 12 months:

  • Birth to 2 months = 5 to 20 pounds.
  • 4 Months = 15 to 25 pounds
  • 6 months = 25 to 35 pounds
  • 12 months = 30 to 55 pounds (More if they are a bigger type.)

What is the Size of a Full-Grown Pit Bull?

I’ve talked about the fact that, among pitbull breeds, there are differences that can impact their final weight and size. For example, the term “Pit Bull” is generally accepted to refer to the American Pit Bull Terrier. However, it can also refer to the Staffordshire Bull Terrier, which is significantly smaller.

According to the United Kennel Club and their Pit Bull Breed Standards, the following weight and height are ideal:

  • American Pit Bull Terrier, Male = 35 to 60 pounds and 18 t0 21 inches.
  • American Pit Bull Terrier, Female = 30 to 50 pounds and 17 to 20 inches.
  • Staffordshire Pit Bull Terrier, Male = 28 to 38 pounds and 15 to 16 inches.
  • Staffordshire Pit Bull Terrier, Female = 24 to 34 pounds and 12 to 15 inches.

Final Thoughts

When does a pitbull puppy stop growing? No, the answer isn’t “whenever it feels like it,” but instead between 2 and 3 years of age. Most of their noticeable growth, though, will occur between 4 and 8 months of age, at which time they’ll also be teething.
