Jack Russell Terriers can range in size as much as they can range in personalities
Most individuals who are contemplating adopting a Jack Russell Terrier are likely curious about how big a full-grown Jack Russell will mature to
How big is a full-grown Jack Russell?
I have been raising a Jack Russell for the past few years, and here is what I can tell you on this topic
Jack Russell Terriers, on average, will range from 10-15 inches tall at the shoulder and weigh between 13-17 pounds when fully grown
Jack Russell Terriers can range in size and weight due to breeding and depending on if they are a mixed dog breed
The rest of this brief post will detail what factors impact how big a Jack Russell Terrier will be when fully grown and some of the common heights and weights you can expect from different Jack Russell Terriers mixed breeds

How Big Is A Full-Grown Jack Russell + Sizing for Male and Female Jack Russells?
Jack Russell Terrier’s start small and adorable, and one of the best physical characteristics of the Jack Russell Terrier is that they remain small and adorable
A common question that individuals ask about Jack Russells is when they can expect their Jack Russell to be considered full-grown
Jack Russells are considered full-grown when they are 6-8 months of age
Of course, this may vary with every Jack Russell as some Jack Russell Terriers may continue to fill-out of bulk up until they are about 1 year old
Especially with routine exercise that is promoting a healthy lifestyle and muscle gain
Assuming your Jack Russell Terrier is full-grown or between that 8-12 months of age, here is the height and weights you can expect to see
Remember, this is the averages, and all Jack Russells are different

How Heavy Will A Jack Russell Get?
You can refer to the information in the table we just illustrated, but in general, a Jack Russell Terrier will reach about 12-17lbs in weight
Some Jack Russells may be on the lower end of this weight, and some may push the higher end of the weight based on the diet, exercise, and muscle mass
Again, all Jack Russells are different, but for the most part, you can bank on your Jack Russell weighing 12-17lbs
If you are concerned about your Jack Russell being overweight, talk to your veterinarian so you can avoid any potential health issues

What Can Impact the Growth and Size of a Jack Russell Terrier
What Can Impact the Growth and Size of a Jack Russell Terrier
Something some of you may not know is that a few factors can even impact how much growth your Jack Russell experiences and how big they ultimately get
I wanted to cover a few of those factors in this post:
While diet is unlikely to cause much of an impact on your Jack Russells growth, it could if it becomes an issue with a lack of nutrients or nutritional needs that your Jack Russell has to remain healthy
You want to avoid your Jack Russell ever lacking any of these nutrients
Stick with recommended and trusted brands for your dog food
As with most dog breeds, genetics plays a vital role in how big a Jack Russell will ultimately be
If you adopt or adopted your Jack Russell Terrier from a local breeder near you, you can ask to meet the parents of your Jack Russell to get a better idea of how big your JR will grow too at full size
Exercise Routines
Exercise may not stunt the height of your Jack Russell but can impact the muscle mass they develop which can ultimately impact the overall weight
Jack Russell Terriers are a strong dog breed with broad muscles and broad chest bones
They are also a hyper dog breed
They need the ability to exercise every day, ideally to remain in optimal health
Other health problems may be out of your control for the most part and should not be a significant factor in your Jack Russells growth but could potentially
Be sure to always get your Jack Russell checked up by a certified vet once per year to ensure they are at peak health
Is A Jack Russell Terrier A Small or Medium Dog?
The Jack Russell Terrier is technically classified as a small dog, but clearly, smaller dogs do exist
If you are looking for a small dog that would be considered a lap dog, a Jack Russell Terrier is a good option for you
Just be sure to exercise and tucker them out if you want them to relax during this cuddle time

Hopefully, this brief post gave you insight into how big a Jack Russell will grow and what height and weights you can expect with your Jack Russell going forward

In this article, we will answer all these relevant questions related to Jack Russell Terrier growth and weightIf you do not own the Jack Russell Terrier yet, make sure you purchase your Jack Russell Terrier from an reputable Jack Russell Terrier breeder
Also, check out our Jack Russell Terrier buying guide and Jack Russell Terrier price guide hereYou can also work with a reputable rescue to adopt a puppyIt is important for you as a caring Jack Russell Terrier owner to know if your Jack Russell Terrier is growing normally and that your Jack Russell Terrier is not overweight or underweightExtensive 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 Jack Russell Terrier`s weight and growth is that your Jack Russell Terrier`s weight and growth pattern can tell you if your Jack Russell Terrier has some underlying health conditions (such as bone, heart, hormone diseases)

This article also contains the Jack Russell Terrier growth chart and weight calculator that you can use to approximately tell if your Jack Russell Terrier`s weight is in the normal range
However, the more accurate method to predict and track normal growth in your Jack Russell Terrier is by regularly weighing your Jack Russell Terrier and recording the weight of your Jack Russell Terrier with our free dog weight tracker and weight predictor
Our tool will tell you, first, a more accurate future weight of your Jack Russell Terrier and, second, if your Jack Russell Terrier 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 Jack Russell Terrier weight category

This is How to TellPuppy growth predictors, growth charts, and growth calculators like the ones above are approximate methods for predicting growth in dogs
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 Jack Russell Terrier will give you a clearer picture of how your Jack Russell Terrier is growing
You can use our free tool to track your Jack Russell Terrier`s growth and weight over time
Our tool will also let you know if your Jack Russell Terrier is growing normally
Tracking your Jack Russell Terrier`s weight will let you see the unique growth trajectory of your Jack Russell Terrier
You can use this growth trajectory to accurately predict how big your Jack Russell Terrier will get
The growth trajectory will also let you know very early if your Jack Russell Terrier 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 Jack Russell Terriers
You can compare your Jack Russell Terrier growth trajectory against these references to see if your Jack Russell Terrier is growing normally or you can use our automatic tool

There are two methods you can use to measure your Jack Russell Terrier`s weight
The first method, which is the better and more accurate method to weigh your Jack Russell Terrier, is to use a dog weighing scaleUsing a dog scale is important if you would like to monitor your Jack Russell Terrier`s growth regularly to catch any abnormal growth earlyHaving a scale for weighing your Jack Russell Terrier will make it easy for you to weigh your Jack Russell Terrier regularly without any trouble
The scale that we recommend for weighing the Jack Russell Terrier is this high durability and affordable Greater Goods Digital Pet Scale

Pet Scale for Accurately Weighing Your Jack Russell Terrier
The second method is to use a bathroom scale to weigh yourself while holding your Jack Russell Terrier
Then use the same scale to weigh yourself without your Jack Russell Terrier
Then calculate your weight when holding your dog minus your weight when not holding your Jack Russell Terrier
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 Jack Russell Terrier if your Jack Russell Terrier is very heavy or if your Jack Russell Terrier is the type that would not stay still while being held

As mentioned earlier in this article, a very accurate way to know if your Jack Russell Terrier 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 Jack Russell Terrier puppy
And a close look at your puppy`s growth trajectory will tell you if your Jack Russell Terrier puppy will be overweight or underweight
This method is relatively easy to use
You can use our free online tool to track your Jack Russell Terrier puppy`s growth curve
However, if you do not have a record of the weekly weights of your Jack Russell Terrier, 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
Overweight, Underweight and Ideal Weight Body Condition Chart for Dogs
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 Jack Russell Terrier appears to be overweight
The vet might recommend reducing how much food to feed your Jack Russell Terrier
Conclusion on Jack Russell Terrier 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 Jack Russell Terrier will get
These tools will also help tell if your Jack Russell Terrier is growing normally
However, the best way to monitor and predict the growth of your Jack Russell Terrier is to measure and record your puppy Jack Russell Terrier`s weight every week
Use our free Jack Russell Terrier weight tracker and calculator tool available here to track and predict your Jack Russell Terrier`s weight
It is important that every Jack Russell Terrier owner monitors the growth of their Jack Russell Terrier for normal growth by checking the weight of their Jack Russell Terrier 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 Jack Russell Terrier is growing normally from your Jack Russell Terrier`s weight history earlier in this article
Abnormal growth in Jack Russell Terrier 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 Jack Russell Terrier lifespan and quality of life
