American Bulldog Growth
Did you just get the American Bulldog puppy? And do you want to know when your American Bulldog will stop growing and how big your American Bulldog will get? Or do you want to know if your American Bulldog is of the ideal weight for its age?
In this article, we will answer all these relevant questions related to American Bulldog growth and weight.
If you do not own the American Bulldog yet, make sure you purchase your American Bulldog from an reputable American Bulldog breeder. Also, check out our American Bulldog buying guide and American Bulldog price guide here.
You can also work with a reputable rescue to adopt a puppy.
It is important for you as a caring American Bulldog owner to know if your American Bulldog is growing normally and that your American Bulldog is not overweight or underweight.
Extensive research studies have shown that most dogs are overweight because their owners spoil them with food, treats, and easy life styles. Most dogs eat way too much and do not get enough exercise. Research has also shown that one of the reasons many dogs die young is because they are overweight. However, you can extend your dog`s life by making sure your dog is of healthy weight and growth.One final reason to keep track of your American Bulldog`s weight and growth is that your American Bulldog`s weight and growth pattern can tell you if your American Bulldog has some underlying health conditions (such as bone, heart, hormone diseases). This is what recent research has shown.
This article contains the American Bulldog growth calculator that you can use to predict your American Bulldog`s adult weight. This article also contains the American Bulldog growth chart and weight calculator that you can use to approximately tell if your American Bulldog`s weight is in the normal range.
However, the more accurate method to predict and track normal growth in your American Bulldog is by regularly weighing your American Bulldog and recording the weight of your American Bulldog with our free dog weight tracker and weight predictor. Our tool will tell you, first, a more accurate future weight of your American Bulldog and, second, if your American Bulldog is growing normally.
We designed our dog weight tracker and weight predictor based on a recent research study carried out by researchers from Banfield Pet Hospitals and the University of Liverpool. This study collected and analyzed the weight of over 6 million healthy dogs in the United States. The dogs studied included dogs in the American Bulldog weight category.

When do American Bulldogs Stop Growing and How Big Do They Get?
Your American Bulldog will grow very fast in its first 51 weeks. At 51 weeks, your American Bulldog will have reached 95 percent of its adult weight. Then your American Bulldog will slowly stop adding more weight. At around 72 weeks (~17 months), your American Bulldog should be at its maximum weight. American Bulldogs stop growing at 72 weeks (~17 months).
The above discussion is general, and it applies to both male and female American Bulldogs. However, male dogs usually grow at a different rate compared to female dogs
A male American Bulldog will grow very fast in its first 53 weeks. At 53 weeks, a male American Bulldog will have reached 95 percent of its adult weight at 53 weeks. A male American Bulldog will then slowly stop adding more weight. At around 73 weeks (~17 months), a male American Bulldog should have reached its maximum weight. Male American Bulldogs stop growing at 73 weeks (~17 months).
Similarly, a female American Bulldog will grow very fast in its first 48 weeks. At 48 weeks, a female American Bulldog will have reached 95 percent of its adult weight at 48 weeks. A female American Bulldog will then slowly stop adding more weight. At around 69 weeks (~17 months), a female American Bulldog should have reached its maximum weight. Female American Bulldogs stop growing at 69 weeks (~17 months).
See the growth graph of a American Bulldog below.
As you can see in the American Bulldog growth curve below, the American Bulldog grows really fast in its early weeks, and then its growth levels off till it reaches 100 percent of the adult weight.
American Bulldog Growth Calculator
Use the calculator below to estimate how big your American Bulldog will get based on its current weight.
This American Bulldog growth calculator is based on the typical weight curve of a American Bulldog shown above. The calculator assumes that your American Bulldog is growing normally, and not on its way to become overweight or underweight.
How Much Should a American Bulldog Weigh?
Adult American Bulldogs typically weigh between 60 to 120 pounds.
Above is a graph that shows how much a American Bulldog should weigh at different ages. Check where the weight of your American Bulldog falls in the graph for its age.
It is totally fine if the weight of your American Bulldog falls in either the dark green or light green region of the graph. However, weight in the dark green region is more typical for American Bulldogs.
If the weight of your American Bulldog falls outside both the dark and light green region for its age, then you should consult a vet.
Also, you can use the American Bulldog weight calculator below to find the typical weight and the normal weight range of American Bulldogs, male or female, of any age between 12 weeks and 100 weeks.
If you want to see how the weight of your American Bulldog compares to that of other American Bulldog`s of its age, enter the weight of your American Bulldog in the calculator, and the calculator will show you where your American Bulldog stands on the weight chart.
The calculator will also tell you if your American Bulldog is within the normal weight range for the American Bulldog.
This American Bulldog weight calculator uses information from belpatt.fr and data from a research study on dog weight carried out by researchers at the University of Liverpool.
Please, talk to your vet before taking any decision on your pet`s weight and health.
What is the Height of the American Bulldog?
The adult American Bulldog is 20 to 28 inches. This is the average adult height of the American Bulldog.
Is Your American Bulldog Growing Normally? This is How to Tell
Puppy growth predictors, growth charts, and growth calculators like the ones above are approximate methods for predicting growth in dogs. However, these tools have limited capabilities. This is because each dog is unique and a dog`s growth may be different from that of the overall dog population.
A more accurate and scientific way to predict a dog`s growth is to measure the dog`s weight every week and record the weight. Doing this with your American Bulldog will give you a clearer picture of how your American Bulldog is growing.
You can use our free tool to track your American Bulldog`s growth and weight over time. Our tool will also let you know if your American Bulldog is growing normally.
Tracking your American Bulldog`s weight will let you see the unique growth trajectory of your American Bulldog. You can use this growth trajectory to accurately predict how big your American Bulldog will get. The growth trajectory will also let you know very early if your American Bulldog will become overweight or underweight.
Monitoring your dog`s weight is important because pet obesity is one of the leading causes of premature death in dogs. And these days, pets gain weight very easily because their owners spoil them with lots of treats and food. Catching early abnormal weight in your dog and correcting it (through diet changes, exercise) can significantly extend your dog`s life.
Below is what a normal growth pattern and what abnormal growth patterns look like in American Bulldogs. You can compare your American Bulldog growth trajectory against these references to see if your American Bulldog is growing normally or you can use our automatic tool.
How to Measure the Weight of your American Bulldog
There are two methods you can use to measure your American Bulldog`s weight.
The first method, which is the better and more accurate method to weigh your American Bulldog, is to use a dog weighing scale.
Using a dog scale is important if you would like to monitor your American Bulldog`s growth regularly to catch any abnormal growth early.
Having a scale for weighing your American Bulldog will make it easy for you to weigh your American Bulldog regularly without any trouble.
The scale that we recommend for weighing the American Bulldog is this high durability and affordable W.C Redmon Precision Digital Pet Scale. Click here to check out this scale on Amazon.
The second method is to use a bathroom scale to weigh yourself while holding your American Bulldog. Then use the same scale to weigh yourself without your American Bulldog. Then calculate your weight when holding your dog minus your weight when not holding your American Bulldog. This method is illustrated in the picture below.
However, note that this method of holding your dog on a scale is not very accurate, and it may be difficult for you to use this method to weigh your American Bulldog if your American Bulldog is very heavy or if your American Bulldog is the type that would not stay still while being held.

American Bulldog Growth Stages
Your American Bulldog will go through a number of developmental stages on its journey to adulthood. Your American Bulldog`s growth pattern can be categorized into 6 distinct stages: Neonatal, Transitional, Socialization Period, Juvenile Period, Adolescent Period, and Maturity.
You can know the developmental stage of your American Bulldog based on how old your American Bulldog is.
1. American Bulldog Neonatal Period
American Bulldog Neonatal Period is from Birth to 2 weeks. During this stage, the American Bulldog puppy will be totally dependent on its mother. The American Bulldog puppy`s eyes will still be unopened with no sense of vision. The American Bulldog puppy will only have the senses of taste and touch
2. American Bulldog Transitional Period
American Bulldog Transitional Period is from 2 weeks to 3 weeks. During this stage, the American Bulldog puppy will continue to develop a better sense of hearing and taste. The puppy`s teeth will start coming through and its eyes will begin to open.
During this stage, the American Bulldog puppy begins to crawl forward and backward, begins to stand, begins to wag its tail. This is also the age where your puppy’s personality begins to develop.
3. American Bulldog Socialization Period
American Bulldog Socialization Period is from 3 weeks to 14 weeks. During this stage, the American Bulldog puppy will be able to fully use all of its senses (vision, smell, touch, hearing, taste), and the puppy will learn to survive without its mother.
Also during this stage, the American Bulldog puppy learns how to act like a dog (biting, chasing, barking, etc). The rapid learning and socialization of the puppy occur at this stage, and what the American Bulldog puppy learns in this stage will have a long-term effect on the puppy`s behavior as an adult.
4. American Bulldog Juvenile Period
American Bulldog Juvenile Period is from 3-4 Months to 5-14 months. During this stage, the American Bulldog puppies will attempt to clarify and resolve their boundaries. Their baby teeth start getting replaced by adult teeth.

How to Tell If Your American Bulldog is Overweight
As mentioned earlier in this article, a very accurate way to know if your American Bulldog puppy is on its way to becoming overweight is by weighing your dog every week and recording its weight. This will show you the growth trajectory of your American Bulldog puppy. And a close look at your puppy`s growth trajectory will tell you if your American Bulldog puppy will be overweight or underweight. This method is relatively easy to use.
You can use our free online tool to track your American Bulldog puppy`s growth curve.
However, if you do not have a record of the weekly weights of your American Bulldog, and you want to tell if your dog is overweight, underweight, or of normal weight, then you can use a chart called the body condition chart shown below. This method requires some expertise to use, and it is further discussed below.
To tell your dog`s body condition, first, look at your dog closely and observe which of its bones and structures are sticking out or not sticking out from under its skin. Next, use your hands to feel for fat and bones over your dog. To know which bones to look and feel for, check out the body condition tool guide from the World Small Animal Veterinary Association and this guide. This exercise will tell you the body condition score for your dog.
Body condition scores are from a scale of 1 to 9. A score of 1, 2 or 3 means that a dog is too skinny. A score of 4 or 5 means that a dog is of ideal weight, and a score above 5 means that a dog is overweight.
Talk to your vet if your American Bulldog appears to be overweight. The vet might recommend reducing how much food to feed your American Bulldog.
Conclusion on American Bulldog Weight and Growth
In this article, we have provided you with the information, growth charts and growth calculators to help you tell how big your American Bulldog will get. These tools will also help tell if your American Bulldog is growing normally.
However, the best way to monitor and predict the growth of your American Bulldog is to measure and record your puppy American Bulldog`s weight every week.
Use our free American Bulldog weight tracker and calculator tool available here to track and predict your American Bulldog`s weight.
It is important that every American Bulldog owner monitors the growth of their American Bulldog for normal growth by checking the weight of their American Bulldog regularly. Regular weight monitoring will let you detect any abnormal growth very early before it is too late. We discussed how you can tell if your American Bulldog is growing normally from your American Bulldog`s weight history earlier in this article.
Abnormal growth in American Bulldog can be because of underlying disease (such are heart, hormonal, or bone problems) or because of overfeeding or underfeeding. All of the aforementioned reduce the American Bulldog lifespan and quality of life.
