Border Collie Growth

Did you just get the Border Collie puppy? And do you want to know when your Border Collie will stop growing and how big your Border Collie will get? Or do you want to know if your Border Collie is of the ideal weight for its age?

In this article, we will answer all these relevant questions related to Border Collie growth and weight.

If you do not own the Border Collie yet, make sure you purchase your Border Collie from an reputable Border Collie breeder. Also, check out our Border Collie buying guide and Border Collie price guide here.

You can also work with a reputable rescue to adopt a puppy.

It is important for you as a caring Border Collie owner to know if your Border Collie is growing normally and that your Border Collie 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 Border Collie`s weight and growth is that your Border Collie`s weight and growth pattern can tell you if your Border Collie has some underlying health conditions (such as bone, heart, hormone diseases). This is what recent research has shown.

This article contains the Border Collie growth calculator that you can use to predict your Border Collie`s adult weight. This article also contains the Border Collie growth chart and weight calculator that you can use to approximately tell if your Border Collie`s weight is in the normal range.

However, the more accurate method to predict and track normal growth in your Border Collie is by regularly weighing your Border Collie and recording the weight of your Border Collie with our free dog weight tracker and weight predictor. Our tool will tell you, first, a more accurate future weight of your Border Collie and, second, if your Border Collie 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 Border Collie weight category.

When do Border Collies Stop Growing and How Big Do They Get?

Your Border Collie will grow very fast in its first 40 weeks. At 40 weeks, your Border Collie will have reached 95 percent of its adult weight. Then your Border Collie will slowly stop adding more weight. At around 52 weeks (~12 months), your Border Collie should be at its maximum weight. Border Collies stop growing at 52 weeks (~12 months).

The above discussion is general, and it applies to both male and female Border Collies. However, male dogs usually grow at a different rate compared to female dogs

A male Border Collie will grow very fast in its first 40 weeks. At 40 weeks, a male Border Collie will have reached 95 percent of its adult weight at 40 weeks. A male Border Collie will then slowly stop adding more weight. At around 51 weeks (~12 months), a male Border Collie should have reached its maximum weight. Male Border Collies stop growing at 51 weeks (~12 months).

Similarly, a female Border Collie will grow very fast in its first 40 weeks. At 40 weeks, a female Border Collie will have reached 95 percent of its adult weight at 40 weeks. A female Border Collie will then slowly stop adding more weight. At around 53 weeks (~12 months), a female Border Collie should have reached its maximum weight. Female Border Collies stop growing at 53 weeks (~12 months).

See the growth graph of a Border Collie below.

As you can see in the Border Collie growth curve below, the Border Collie grows really fast in its early weeks, and then its growth levels off till it reaches 100 percent of the adult weight.

Growth Curve of a Border Collie

Border Collie Growth Calculator

Use the calculator below to estimate how big your Border Collie will get based on its current weight.

This Border Collie growth calculator is based on the typical weight curve of a Border Collie shown above. The calculator assumes that your Border Collie is growing normally, and not on its way to become overweight or underweight.

How Much Should a Border Collie Weigh?

Weight of the Border Collie. Weight in the dark green region is typical, though weight in the light green region is also possible

Adult Border Collies typically weigh between 30 to 45 pounds.

Above is a graph that shows how much a Border Collie should weigh at different ages. Check where the weight of your Border Collie falls in the graph for its age.

It is totally fine if the weight of your Border Collie falls in either the dark green or light green region of the graph. However, weight in the dark green region is more typical for Border Collies.

If the weight of your Border Collie falls outside both the dark and light green region for its age, then you should consult a vet.

Also, you can use the Border Collie weight calculator below to find the typical weight and the normal weight range of Border Collies, male or female, of any age between 12 weeks and 100 weeks.

If you want to see how the weight of your Border Collie compares to that of other Border Collie`s of its age, enter the weight of your Border Collie in the calculator, and the calculator will show you where your Border Collie stands on the weight chart.

The calculator will also tell you if your Border Collie is within the normal weight range for the Border Collie.

This Border Collie 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 Border Collie?

The adult Border Collie is 18 to 22 inches tall at the shoulder. This is the average adult height of the Border Collie.

Is Your Border Collie 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 Border Collie will give you a clearer picture of how your Border Collie is growing.

You can use our free tool to track your Border Collie`s growth and weight over time. Our tool will also let you know if your Border Collie is growing normally.

Tracking your Border Collie`s weight will let you see the unique growth trajectory of your Border Collie. You can use this growth trajectory to accurately predict how big your Border Collie will get. The growth trajectory will also let you know very early if your Border Collie 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 Border Collies. You can compare your Border Collie growth trajectory against these references to see if your Border Collie is growing normally or you can use our automatic tool.

How to Measure the Weight of your Border Collie

There are two methods you can use to measure your Border Collie`s weight.

The first method, which is the better and more accurate method to weigh your Border Collie, is to use a dog weighing scale.

Using a dog scale is important if you would like to monitor your Border Collie`s growth regularly to catch any abnormal growth early.

Having a scale for weighing your Border Collie will make it easy for you to weigh your Border Collie regularly without any trouble.

The scale that we recommend for weighing the Border Collie is this high durability and affordable W.C Redmon Precision Digital Pet Scale. Click here to check out this scale on Amazon.

Pet Scale for Accurately Weighing Your Border Collie

The second method is to use a bathroom scale to weigh yourself while holding your Border Collie. Then use the same scale to weigh yourself without your Border Collie. Then calculate your weight when holding your dog minus your weight when not holding your Border Collie. 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 Border Collie if your Border Collie is very heavy or if your Border Collie is the type that would not stay still while being held.

Border Collie Growth Stages

Your Border Collie will go through a number of developmental stages on its journey to adulthood. Your Border Collie`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 Border Collie based on how old your Border Collie is.

1. Border Collie Neonatal Period

Border Collie Neonatal Period is from Birth to 2 weeks. During this stage, the Border Collie puppy will be totally dependent on its mother. The Border Collie puppy`s eyes will still be unopened with no sense of vision. The Border Collie puppy will only have the senses of taste and touch

2. Border Collie Transitional Period

Border Collie Transitional Period is from 2 weeks to 3 weeks. During this stage, the Border Collie 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 Border Collie 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. Border Collie Socialization Period

Border Collie Socialization Period is from 3 weeks to 14 weeks. During this stage, the Border Collie 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 Border Collie 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 Border Collie puppy learns in this stage will have a long-term effect on the puppy`s behavior as an adult.

4. Border Collie Juvenile Period

Border Collie Juvenile Period is from 3-4 Months to 5-14 months. During this stage, the Border Collie puppies will attempt to clarify and resolve their boundaries. Their baby teeth start getting replaced by adult teeth.

5. Border Collie Adolescent Period

Border Collie Adolescent Period is from 5-14 Months to 2-3 Years. Border Collies go through social and sexual maturity during this stage.

6. Border Collie Maturity Period

Border Collie Maturity Period is from 1 year to 4 years. At this age, your Border Collie will transition to full adulthood.

How to Tell If Your Border Collie is Overweight

As mentioned earlier in this article, a very accurate way to know if your Border Collie 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 Border Collie puppy. And a close look at your puppy`s growth trajectory will tell you if your Border Collie puppy will be overweight or underweight. This method is relatively easy to use.

You can use our free online tool to track your Border Collie puppy`s growth curve.

However, if you do not have a record of the weekly weights of your Border Collie, 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 Border Collie appears to be overweight. The vet might recommend reducing how much food to feed your Border Collie.

Conclusion on Border Collie 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 Border Collie will get. These tools will also help tell if your Border Collie is growing normally.

However, the best way to monitor and predict the growth of your Border Collie is to measure and record your puppy Border Collie`s weight every week.

Use our free Border Collie weight tracker and calculator tool available here to track and predict your Border Collie`s weight.

It is important that every Border Collie owner monitors the growth of their Border Collie for normal growth by checking the weight of their Border Collie 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 Border Collie is growing normally from your Border Collie`s weight history earlier in this article.

Abnormal growth in Border Collie 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 Border Collie lifespan and quality of life.
