Collie Growth

Did you just get a Collie puppy? And do you want to know when your Collie will stop growing and how big your Collie will get? Or do you want to know if your Collie is of the ideal weight for its age? In this article, we will answer all relevant questions related to Collie growth and weight.

If you do not own the Collie yet, make sure you purchase your Collie from an ethical Collie breeder or work with a reputable rescue. Check out our Collie buying guide and Collie price guide here.

It is important for you as a caring Collie owner to know if your Collie is growing normally and if your 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 an easy life. 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. You can extend your dog`s life by making sure your dog is of healthy weight and growth. One final reason why you must keep track of your Collie`s weight and growth is that your Collie`s weight and growth pattern can tell you if your Collie has some underlying health conditions (such as bone, heart, hormone diseases). This is what recent research has shown. This article contains the Collie growth calculator that you can use to predict your Collie`s adult weight. This article also contains the Collie growth chart and weight calculator that you can use to approximately tell if your Collie`s weight is in the normal range based on its current weight. However, the more accurate method to predict and track normal growth in your Collie is by regularly weighing your Collie and recording the weight of your Collie with our free dog weight tracker and weight predictor. Our tool will tell you, first, a more accurate future weight of your Collie and, second, if your 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 Collie weight category.

Collie Weight and Growth Chart

Below is the typical growth chart and weight chart of Collies at different stages in their lives.

Note that your Collie may be slightly heavier or lighter than what the chart says. The growth chart is an average weight chart.

Also, this growth chart is the combined growth chart of the male and female Collie.

Note that the growth pattern of a female Collie can be slightly different from the growth pattern of a male Collie

. Therefore, later on in this article, we will provide you with the gender-specific growth chart for the male and for the female Collie.

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

Your Collie will grow very fast in its first 44 weeks. At 44 weeks, your Collie will have reached 95 percent of its adult weight. Then your Collie will slowly stop adding more weight. At around 58 weeks (~14 months), your Collie should be at its maximum weight. Collies stop growing at 58 weeks (~14 months).

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

A male Collie will grow very fast in its first 44 weeks. At 44 weeks, a male Collie will have reached 95 percent of its adult weight at 44 weeks. A male Collie will then slowly stop adding more weight. At around 58 weeks (~14 months), a male Collie should have reached its maximum weight. Male Collies stop growing at 58 weeks (~14 months).

Similarly, a female Collie will grow very fast in its first 44 weeks. At 44 weeks, a female Collie will have reached 95 percent of its adult weight at 44 weeks. A female Collie will then slowly stop adding more weight. At around 58 weeks (~14 months), a female Collie should have reached its maximum weight. Female Collies stop growing at 58 weeks (~14 months).

See the growth graph of a Collie below.

As you can see in the Collie growth curve below, the 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 Collie

Collie Growth Calculator

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

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

How Much Should a Collie Weigh?

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

Collies typically weigh between 50 to 70 pounds.

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

It is totally fine if the weight of your 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 Collies.

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

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

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

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

This 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 Collie?

The adult Collie is 22 to 26 inches all at the shoulder. This is the average adult height of the Collie.

Is Your Collie Growing Normally? This is How to Tell

Puppy growth predictors, growth charts, and growth calculators are approximate methods for determining normal growth in dogs. However, these tools have limited capacity. This is because each dog is unique and a dog`s growth may be different from that of the overall dog population. Therefore, a more accurate and scientific way to track a dog`s growth is to measure its weight every week and record the weight. Doing this with your Collie will give you a clearer picture of how your Collie is growing. You can use our free tool to track your Collie`s growth and weight over time. Tracking your Collie`s weight will let you see the unique growth trajectory of your Collie. You can use this growth trajectory to accurately predict how big your Collie will get. The growth trajectory will also let you know very early if your Collie will become overweight or underweight. 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 Collies. You can compare your Collie growth trajectory against these references to see if your Collie is growing normally.

How to Measure the Weight of your Collie

There are two methods you can use to measure your Collie`s weight. The first method and the better and accurate method to weigh your Collie is to use a dog weighing scale.

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

Having a scale for weighing your Collie will make it easy for you to weigh your Collie regularly without any hassle. The scale that we recommend for weighing the 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 Collie
The second method is to use a bathroom scale to weigh yourself while holding your Collie. Then use the same scale to weigh yourself without your Collie. Then calculate your weight when holding your dog minus your weight when not holding your Collie. This method is illustrated in the picture below. However, note that this method is not very accurate, and it may be difficult for you to use this method to weigh your Collie if your Collie is very heavy or if your Collie is the type that would not stay still while being held.

Collie Growth Stages

Your Collie will go through a number of developmental stages on its journey to adulthood. Your Collie`s growth pattern can be categorized into 6 distinct stages: Neonatal, Transitional, Socialization Period, Juvenile Period, Adolescent Period, and Maturity.

1. Collie Neonatal Period

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

2. Collie Transitional Period

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

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

4. Collie Juvenile Period

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

5. Collie Adolescent Period

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

6. Collie Maturity Period

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

How to Tell If Your Collie is Overweight

As mentioned earlier in this article, a very accurate way to know if your 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 Collie puppy. And a close look at your puppy`s growth trajectory will tell you if your Collie puppy will be overweight or underweight. This method is relatively easy to use. You can use our free online tool to track your Collie puppy`s growth curve. However, if you do not have a record of the weekly weights of your 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.
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 are 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 to 3 means that a dog is too skinny. A score of 4 and 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 Collie appears to be overweight. The vet might recommend reducing how much food your Collie.

Conclusion on 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 Collie will get. These tools will also help tell if your Collie is growing normally. However, the best way to monitor and predict the growth of your Collie is to measure and record your puppy Collie`s weight every week. Use our free Collie weight tracker and calculator tool available here to track and predict your Collie`s weight. It is important that every Collie owner monitor the growth of their Collie for normal growth by checking the weight of their 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 Collie is growing normally from your Collie`s weight history earlier in this article. Abnormal growth in 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 Collie lifespan and quality of life. Don`t wait. Start tracking your Collie`s weight today!
