When Do Border Collies Stop Growing?

It’s great to know when your Border Collie has achieved its maximum size because it lets you know what to expect.

If you’re not sure how large your dog can get, you can waste time worrying about why it’s not growing or if it’s already too big. As a result, it’s natural to question how tall a border collie grows.

Border Collies often stop developing between the ages of 12.5 and 15.5 months. Some of them will continue to gain weight beyond 15 months, but this normally ceases at 18 months.

Border Collies are regarded to be medium-sized dogs, with the average male growing to be 18 to 23 inches tall and weighing up to 45 pounds as an adult.

While their female counterparts are slightly smaller, they can reach heights of 17 to 20 inches and weights of 27 to 41 pounds as adults.

Border Collie Size Chart

Border Collies have an average height of 22 to 27 inches (56 to 69 cm) and a weight of 27 to 45 pounds (12 to 20 kg). Their length ranges from 28 to 34 inches (71 to 86 cm) and their withers range from 18 to 22 inches (46 to 56 cm).

However, depending on your Border Collie puppy’s or dog’s age or gender, there are several techniques to determine their weight.

Border Collie Weight Calculator

Method 1 for calculating size

Assume your Border Collie’s weight falls between two figures on the scale. All you need to do is take the mean of the two.

If your puppy weighs 26 pounds at 11 months, he falls between the ranges of 24 and 27 pounds on the table above. Take the average of 24 and 27, then divide it by two to get his adult weight of 25.5 lbs.

Method 2 for calculating size

The second method for determining your Border Collie puppy’s adult weight is to divide his present weight by his current age in weeks.

For example, at 13 weeks, your dog weighs 8 pounds (8/13=0.61). Multiply the figure (0.61) by 52 (the largest value on our chart) to get 32 pounds.

According to that formula, a Border Collie puppy weighing 8 pounds at 13 weeks will likely weigh 32 pounds as an adult.

Method 3 of calculating size 3

If your puppy is 14 weeks or older, use this. All you have to do is weigh your puppy during his 14th week or look through his records to see what he weighed at that age. Divide it by two and add it to half of his weight at 14 weeks.

Assume your Border dog weighs 10 pounds at 14 weeks. If you double that by two, you get 20 pounds. Add that to half his weight at 14 weeks, which is 5, for a total of 25 lbs.

What is the Standard Border Collie Size

Border Collies are medium-sized dogs with strong, athletic legs and slim bodies, as do most herding breeds, to enhance agility, speed, and endurance.

A typical border collie stands between 16 and 22 inches tall, with males being slightly taller than females. Border Collie puppies mature swiftly when they are less than a year old, and they are completely developed by 18 months.

Border Collie Growth Chart – What To Expect
Border Collie Weight Chart by Age


Border Collie Weight  1-2 weeks

The average birth weight of a Border Collie is 7-14 ounces. Puppies may lose water weight in the first 24 hours. Following that, they should instantly begin to gain weight.

Within the first week to six weeks, your Border collie puppy’s weight should have doubled. At least 12 to 12 ounces every day. Other important milestones to watch for during this time include their first crawl, opening their eyes, and obtaining their primary or baby teeth.

Border Collie Weight 3-12 weeks

Your Border Collie puppy, which weighs about 3 to 6 pounds (1 to 3 kg), should have multiplied its weight four times by the age of six weeks. They’re extremely energetic even as puppies, but they’re only supposed to gain 2 to 4 pounds per week until their 14th week.

The puppies are starting to socialize, not just with their mother or siblings, but with everything in their environment.

It’s a great idea to expose the puppies to new sounds and smells at such a young age, but the Border Collies should remain with their mother. Yes, even if they’ve been weaned. After all, it’s their mother’s job to teach their dog’s social skills.


Border Collie Weight 4-6months

At 14 weeks, that rapid and dramatic weight gain has finally leveled out, and he is likely to gain a pound every week until he is six months old. When contrasted to puppyhood, it will be a progressive process.

Teenage Border Collies eat voraciously when they enter adolescence to support their high levels of energy and metabolism.

At this time, they have all of their puppy teeth and are transitioning to adult teeth, and their motor skills are much more developed.

Border Collie Weight  7-9 months

The Border Collie is now an adolescent at seven months and should weigh around 15 pounds. Your dog is on the verge of sexual maturity.

They would have completely developed adult teeth, as well as fully formed ears with drooping tips. If you own more than one Border Collie, you will discover an unexpected intimacy between them.

Border Collie Weight  10-12 months

The Border Collie is approaching adulthood at this point. They would have grown to a height of 18 to 23 inches as adults. They may appear slender and tall since their weight gain has decreased dramatically.

They are still incredibly busy and hyper-metabolic at 12 months, causing them to lose weight quicker than they gain. To match the energy they exert, you should feed them high-calorie meals.

Border Collie Adult Weight 

The mature Border Collie is really attractive. It should have gained enough weight to fill all of its bones. It has thick, lustrous fur and can weigh between 35 and 45 pounds.

Adult Border Collies have little trouble maintaining a healthy weight. They simply continue to gain weight gradually until they reach their full size. They start behaving like adult dogs and are no longer as active as they once were.

What is the Full Grown Border Collie Weight?

Border Collies should be between 30 and 55 pounds in weight. Adult female Border Collies weigh 30 to 45 pounds on average, whereas adult male Border Collies weigh 40 to 55 pounds.

A mature Border Collie should stand between 19 and 22 inches tall (male) or 18 to 21 inches tall (female), according to the American Kennel Club Official Border Collie Breed Standards (female).

How To Weigh Your Border Collie Puppy?

Do you want to know how to weigh your Border Collie at home? Weighing your puppy will allow you to keep track of their weight and ensure that they are at an appropriate weight for their age.

A bathroom scale is required to weigh your Border Collie at home. To begin, walk onto the scale and weigh yourself. Then, with your puppy in tow, walk on the scale.

Finally, deduct your weight from the combined weight of you and your Border Collie. This is the weight of your puppy.

If your Border Collie can sit still on the scale, you can also purchase a dog scale.

What Is A Border Collie’s Neck Size?

To determine the neck size of your dog, use a soft and flexible tape measure to determine the neck size of your dog where her collar naturally falls. Then, put two fingers between your dog’s neck and the tape measure to ensure that the dog collar fits snugly but comfortably. Basenji’s average neck circumference is between 16 and 18 inches.

How Big Do Border Collies Get?

How big do they get?
How big do they get?

Age is one factor that can influence how big they grow. Border Collies normally need 15 to 18 months to mature. If your Border Collie is under the age of 12 months, he or she is still growing! Check out our growth charts above to get an idea of how big you’ll be after you’re done.

Another method is to examine the size of your Border Collie’s paws. If their paws are huge in comparison to their legs and body, they have a long way to go. Oversized paws are a typical adolescent trait that indicates they are still growing.

If you purchased your Border Collie from a breeder, ask them for an expected weight based on your puppy’s parents and previous litters. Typically, a dog will not grow larger than its largest parent, providing you with a maximum size estimate as well.


Border Collie Body Condition Score (BCS) 

Body Condition Score is similar to BMI in humans. It is used to assess the fat content of animals, especially dogs. There are two scales used, one from 1 to 5 and the other from 1 to 9.

BCS scores are assigned to animals using visualization and palpation. Your Border Collie should have a Body Condition Score of 3/5 or 5/9. The abdominal tuck is evident from the side and the waistline is visible from above in this position.

With this score, the ribs are palpable due to a thin layer of fat, indicating that your puppy’s weight is appropriate for their age category.

Factors That Affect Border Collie Puppy Growth 

Genetics

Some Border Collies may have genetic health issues such as epilepsy and hypodipsia. These issues normally begin when Border Collies are puppies, however, they may not be obvious at first.

Without addressing these issues, the puppy will not mature normally. That is why you should watch your puppy see if they are in pain or if anything is wrong with them.

Early detection and treatment of such illnesses may assist your dog in getting back on track and starting to grow normally.

Diet & Nutrition

A dog that is properly fed and follows a healthy diet will grow healthier and faster than one that is not.

When a Border Collie is provided a well-balanced diet, they will mature at the appropriate age. An improper diet will result in either an underfed or an overweight dog, both of which are hazardous to your dog.

It is acceptable to see a veterinarian for more information on the type of nourishment that is suited for your dog.

Physical Activity & Health

Border Collies are high-energy canines. They can be highly active and enjoy moving about. As a result, they require a lot of physical exercises and cannot function effectively if forced to lounge around all day.

Puppy joints and bones benefit from exercise. It allows individuals to stretch while being healthy and avoiding unhealthy weight gain.

Common Questions about Border Collie

At What Age Is A Border Collie Fully Grown?

Most Border Collies stop developing around the age of 15 months. Larger Border Collies, on the other hand, may take up to 18 months to finish filling out their chest. At roughly a year old, the majority of Border Collies will have reached adult height.

How Long Are Border Collies Pregnant?

Dogs have a normal gestation length of about 63 days from conception, though this can vary by several days. While this may appear to be a simple response, conception is often difficult to determine. Because sperm can survive inside the female for several days and eggs can stay viable for up to 48 hours, the act of mating is not a perfect measurement of gestation. Without the advice of a veterinarian, it is difficult to anticipate the length of the pregnancy.

Hormone measurements provide a far more precise time window for pregnancy. During the breeding phase, several breeders utilize vaginal swabs and blood tests to check reproductive hormones. This assists them in determining the optimal time to breed their buck, as well as the length of gestation and likely due date.

How Many Puppies Do  Border Collies Have?

Border collies are a type of dog that is both athletic and clever. These dogs are very trainable and have a lot of energy. Border collies are known for their remarkable herding abilities, and their typical litter size ranges from four to eight puppies. A collie mother gives birth to six pups on average.

What Is The Life Expectancy Of Border Collies?

Border Collies are a typically healthy breed with a life expectancy of 12-15 years. Some may experience common health issues such as hip dysplasia, epilepsy, and hypothyroidism. Early detection is the key to living a long and happy life, so make routine checks a priority.

How Much Does It Cost To Own A Border Collie?

Border Collies that are supposed to be petted and have complete documentation but are not show quality will cost around $600 and higher. Prepare a budget of $1,300 to $4,500 for a quality puppy with papers, breeding rights, and outstanding ancestry. Occasionally, even more.

How To Help Your Border Collie Lose Weight If He Is Overweight 

As with humans, exercise is critical for your overweight dog’s health. Increased movement helps your dog burn off excess energy (and calories consumed). Avoid panic! Exercising your pet does not have to include marathons or lengthy hikes. Regular walks and the opportunity to run and play safely off-leash.

Even creating a stimulating indoor environment that encourages your dog to exercise on a regular basis can help. Bear in mind that different breeds require varying amounts of exercise, so visit your veterinarian, breeder, or your dog’s breed standard for recommendations on recommended activity levels.

Distinguish Begging from Hunger
Distinguish Begging from Hunger

Distinguish Begging from Hunger

Begging is not necessarily motivated by a desire for more food; it is also used to gain attention. (And, by rewarding the behavior, you reinforce and encourage it to continue.) If your dog begs, do not automatically assume he is hungry. Trust your instincts and keep track of the date and time of your last meal.

If your dog is prone to begging and you are prone to succumb to those puppy dog eyes, choose a high-protein meal with a fiber blend to help control your dog’s hunger and voluntary food consumption. This manner, you may feed your dog with the assurance that he will feel fuller and content for a longer period of time.

Restriction on treats and table scraps

Even when our dogs are not begging, many of us provide an excessive amount of treats and table scraps. Dogs are not required to share our food! Consider treats and scraps for your pet in the same way that you would candy for children to help you keep them in check. If you’re going to utilize snacks for training, choose low-calorie, low-fat ones and keep the portions small.

As an alternative, keep in mind that clickers are excellent for reinforcement… and they have no calories! After all, a few extra pounds can make a significant impact in the lives of dogs, which are significantly smaller than humans. (Even the colossal breeds!) Therefore, focus on a balanced diet and resist the temptation to “reward” them with extra.

Customize Your Dog’s Diet

Not all weight-loss foods are created equal, which is why it’s critical to match your dog’s nutrition plan to their unique needs. Choose a brand that caters to your dog’s unique needs, whether they be weight control, dietary sensitivities, or illnesses.
