Irish Terrier Growth
Did you just get the Irish Terrier puppy? And do you want to know when your Irish Terrier will stop growing and how big your Irish Terrier will get? Or do you want to know if your Irish Terrier is of the ideal weight for its age?
In this article, we will answer all these relevant questions related to Irish Terrier growth and weight.
If you do not own the Irish Terrier yet, make sure you purchase your Irish Terrier from an reputable Irish Terrier breeder. Also, check out our Irish Terrier buying guide and Irish Terrier price guide here.
You can also work with a reputable rescue to adopt a puppy.
It is important for you as a caring Irish Terrier owner to know if your Irish Terrier is growing normally and that your Irish Terrier 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 Irish Terrier`s weight and growth is that your Irish Terrier`s weight and growth pattern can tell you if your Irish Terrier has some underlying health conditions (such as bone, heart, hormone diseases). This is what recent research has shown.
This article contains the Irish Terrier growth calculator that you can use to predict your Irish Terrier`s adult weight. This article also contains the Irish Terrier growth chart and weight calculator that you can use to approximately tell if your Irish Terrier`s weight is in the normal range.
However, the more accurate method to predict and track normal growth in your Irish Terrier is by regularly weighing your Irish Terrier and recording the weight of your Irish Terrier with our free dog weight tracker and weight predictor. Our tool will tell you, first, a more accurate future weight of your Irish Terrier and, second, if your Irish 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 Irish Terrier weight category.
Also, check out our Irish Terrier food calculator here to know how much food to feed your Irish Terrier based on your Irish Terrier`s weight and age.
Irish Terrier Weight and Growth Chart

When do Irish Terriers Stop Growing and How Big Do They Get?
Your Irish Terrier will grow very fast in its first 37 weeks. At 37 weeks, your Irish Terrier will have reached 95 percent of its adult weight. Then your Irish Terrier will slowly stop adding more weight. At around 47 weeks (~11 months), your Irish Terrier should be at its maximum weight. Irish Terriers stop growing at 47 weeks (~11 months).
The above discussion is general, and it applies to both male and female Irish Terriers. However, male dogs usually grow at a different rate compared to female dogs
A male Irish Terrier will grow very fast in its first 37 weeks. At 37 weeks, a male Irish Terrier will have reached 95 percent of its adult weight at 37 weeks. A male Irish Terrier will then slowly stop adding more weight. At around 47 weeks (~11 months), a male Irish Terrier should have reached its maximum weight. Male Irish Terriers stop growing at 47 weeks (~11 months).
Similarly, a female Irish Terrier will grow very fast in its first 37 weeks. At 37 weeks, a female Irish Terrier will have reached 95 percent of its adult weight at 37 weeks. A female Irish Terrier will then slowly stop adding more weight. At around 47 weeks (~11 months), a female Irish Terrier should have reached its maximum weight. Female Irish Terriers stop growing at 47 weeks (~11 months).
See the growth graph of a Irish Terrier below.
As you can see in the Irish Terrier growth curve below, the Irish Terrier grows really fast in its early weeks, and then its growth levels off till it reaches 100 percent of the adult weight.
Irish Terrier Growth Calculator
Use the calculator below to estimate how big your Irish Terrier will get based on its current weight.
This Irish Terrier growth calculator is based on the typical weight curve of a Irish Terrier shown above. The calculator assumes that your Irish Terrier is growing normally, and not on its way to become overweight or underweight.
How Much Should a Irish Terrier Weigh?
Adult Irish Terriers typically weigh between 25 to 27 pounds.
Above is a graph that shows how much a Irish Terrier should weigh at different ages. Check where the weight of your Irish Terrier falls in the graph for its age.
It is totally fine if the weight of your Irish Terrier falls in either the dark green or light green region of the graph. However, weight in the dark green region is more typical for Irish Terriers.
If the weight of your Irish Terrier falls outside both the dark and light green region for its age, then you should consult a vet.
Also, you can use the Irish Terrier weight calculator below to find the typical weight and the normal weight range of Irish Terriers, male or female, of any age between 12 weeks and 100 weeks.
If you want to see how the weight of your Irish Terrier compares to that of other Irish Terrier`s of its age, enter the weight of your Irish Terrier in the calculator, and the calculator will show you where your Irish Terrier stands on the weight chart.
The calculator will also tell you if your Irish Terrier is within the normal weight range for the Irish Terrier.
This Irish Terrier 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 Irish Terrier?
The adult Irish Terrier is 18 to 20 inches tall at the shoulder. This is the average adult height of the Irish Terrier.
Is Your Irish Terrier 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 Irish Terrier will give you a clearer picture of how your Irish Terrier is growing.
You can use our free tool to track your Irish Terrier`s growth and weight over time. Our tool will also let you know if your Irish Terrier is growing normally.
Tracking your Irish Terrier`s weight will let you see the unique growth trajectory of your Irish Terrier. You can use this growth trajectory to accurately predict how big your Irish Terrier will get. The growth trajectory will also let you know very early if your Irish 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 Irish Terriers. You can compare your Irish Terrier growth trajectory against these references to see if your Irish Terrier is growing normally or you can use our automatic tool.
How to Measure the Weight of your Irish Terrier
There are two methods you can use to measure your Irish Terrier`s weight.
The first method, which is the better and more accurate method to weigh your Irish Terrier, is to use a dog weighing scale.
Using a dog scale is important if you would like to monitor your Irish Terrier`s growth regularly to catch any abnormal growth early.
Having a scale for weighing your Irish Terrier will make it easy for you to weigh your Irish Terrier regularly without any trouble.
The scale that we recommend for weighing the Irish Terrier 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 Irish Terrier. Then use the same scale to weigh yourself without your Irish Terrier. Then calculate your weight when holding your dog minus your weight when not holding your Irish 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 Irish Terrier if your Irish Terrier is very heavy or if your Irish Terrier is the type that would not stay still while being held.
How Fast Do Irish Terriers Grow? Irish Terrier Growth Rate
Starting from 3 months of age, Irish Terriers grow at a rate of 0.93 pounds per week (0.42 Kilograms per week) on average. Starting at 4 months, your Irish Terrier will gain 0.74 pounds (0.34 Kilograms) every week on average.
At 5 months of age, your Irish Terrier will grow at a rate of 0.58 pounds per week (0.27 Kilograms per week) on average. Then at 6 months, your Irish Terrier will gain 0.45 pounds (0.20 Kilograms) every week on average.

Irish Terrier Growth Stages
Your Irish Terrier will go through a number of developmental stages on its journey to adulthood. Your Irish Terrier`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 Irish Terrier based on how old your Irish Terrier is.
1. Irish Terrier Neonatal Period
Irish Terrier Neonatal Period is from Birth to 2 weeks. During this stage, the Irish Terrier puppy will be totally dependent on its mother. The Irish Terrier puppy`s eyes will still be unopened with no sense of vision. The Irish Terrier puppy will only have the senses of taste and touch
2. Irish Terrier Transitional Period
Irish Terrier Transitional Period is from 2 weeks to 3 weeks. During this stage, the Irish Terrier 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 Irish Terrier 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. Irish Terrier Socialization Period
Irish Terrier Socialization Period is from 3 weeks to 14 weeks. During this stage, the Irish Terrier 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 Irish Terrier 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 Irish Terrier puppy learns in this stage will have a long-term effect on the puppy`s behavior as an adult.
4. Irish Terrier Juvenile Period
Irish Terrier Juvenile Period is from 3-4 Months to 5-14 months. During this stage, the Irish Terrier puppies will attempt to clarify and resolve their boundaries. Their baby teeth start getting replaced by adult teeth.
5. Irish Terrier Adolescent Period
Irish Terrier Adolescent Period is from 5-14 Months to 2-3 Years. Irish Terriers go through social and sexual maturity during this stage.
6. Irish Terrier Maturity Period
Irish Terrier Maturity Period is from 1 year to 4 years. At this age, your Irish Terrier will transition to full adulthood.

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