When Do Border Collies Calm Down?

By Coty Perry

Border Collies will typically calm down around the age of six. As they mature, they will start to relax but keep in mind that it can vary from dog to dog. Border Collies are known as a naturally hyper breed and some may not calm down until they are much older. 

Is your Border Collie acting crazy, and you’re wondering how long this behavior will last? As many Border Collie owners have the same concern, you are not alone. Border Collies are a naturally intelligent, energetic, and hyper dog breed. You can expect this behavior for most of their life. 

However, once your dog reaches around 6 years of age, you will notice a decline in their hyperactivity as they will no longer be a young dog. Is your Border Collie still high energy even though they are getting older? If your Border Collie is still full of energy after 6 years of age, it might have to do with your dog’s unique personality. 

They might just be more energetic than other dogs their age, which is still expected for Border Collies. In addition, if your Border Collie has ever been trained to remain calm, they will be more energetic than you might expect. With the right balance of exercise, mental stimulation, social activities, and training, you can improve your Border Collie’s behavior and have a better understanding of when do Border Collies calm down.

How Do I Get My Border Collie to Calm Down?

To understand a Border Collie calms down, it is essential first to learn how to help your pup calm down.


If your Border Collie does not receive enough attention, it will cause them to become anxious and hyper. Border Collies are naturally an energetic breed but are even more active when they don’t get the attention they desire. 

Whether you play a game of fetch, take them for a walk, or just pet them and play with their toys, you will notice a positive difference in your dog’s behavior. 

Best Calming Aid to Help My Border Collie Calm Down

A calming aid is a supplement you can give to your Border Collie to support a calm mood. If you give your dog a calming aid, like Harmony, you should notice a difference in your dog’s behavior.

Harmony is a fast-acting supplement that supports a healthy stress response in your pup’s body and will help alleviate their anxiety. 

It is entirely natural and contains Ashwagandha, L-theanine, and Relora, which will help promote a stress-free mindset for your Border Collie in less than 90 minutes.

When you purchase Harmony, you will need to select your dog’s weight and whether or not you want to subscribe to receive the calming aid or make a one-time purchase continuously. 

Routine Exercise

Border collies were bred originally to herd sheep in all types of weather conditions and terrain. Their ancestry makes them an energetic breed today, enabling your Border Collie to excel in canine sports. Since Border Collies are high-energy pets, they need a routine exercise schedule. 

You should allow your Border Collie to get up to 90 minutes of exercise daily, as long as your dog’s vet says they are healthy enough. This exercise can include canine sports like flyball and agility, a game of fetch, or going for a walk or a run. Routine exercise will allow your Border Collie to let out their abundant energy to feel calm throughout the day.

Mental Stimulation

You can do many things to help keep your Border Collie mentally stimulated. However, it is challenging to keep such an intelligent breed mentally stimulated. Essentially, your Border Collie needs exercise for its brain to feel calm. 

A working dog like a Border Collie needs their minds to be worked as it is part of its ancestry, and it is how its mind works. If your dog doesn’t receive enough mental stimulation, it might be destructive, anxious, hyperactive, disobedient, and have chewing issues. 

You can stimulate your pup’s mind by having them use their sense of smell to find a hidden treat, exposing your dog to other dogs and people, playing with an interactive puzzle toy, playing hide and seek, or doing agility training. Another fun thing to do with Border Collies is to name their toys since they are great at successfully identifying dog toys by name.

Timeline of Typical Border Collie Development 


Newborn Border Collie puppies weigh anywhere between 7 ounces and 14 ounces. It is usual for them to lose water weight after birth. However, they will gradually begin to gain the weight back. When Border Collies are born, they have no teeth, are deaf, and are blind. 

0-3 Weeks of Age

This stage in your Border Collie’s life is the neonatal period. You will notice that your Border Collie puppy will have doubled their weight after its first week of life. It is usual for your Border Collie puppy to sleep most of the time, and they will still be reliant on their mother for warmth and milk while they are developing. Border Collie puppies will weigh around 3 pounds at this point.

2-4 Weeks of Age

At this age, your Border Collie puppy will be able to hear, open its eyes, stand, and even begin to walk. Once they reach 4 weeks old, you should start feeding them some solid food but still allow them to drink their mother’s milk. You will notice your puppy is trying to explore more and want to play with its siblings. This is a transitional period for your Border Collie.

4-12 Weeks of Age

You will notice that your Border Collie will depend less on milk from its mother and will want to eat more solid foods. Your puppy will become more social and should begin socializing more with other dogs and people. 

Around 8 weeks old is when you can take your puppy home. You should continue practicing socialization with your puppy, and you can begin basic training at this point. During weeks 4,5, and 9 of your Border Collie’s life, they will start receiving vaccinations from their vet. At this age, your Border Collie can weigh up to 12 pounds. 

3-6 Months of Age

At this age, your Border Collie will be in the “juvenile stage,” and you will notice your puppy trying to test you. This is a great time to set rules for your puppy and teach them those rules consistently. At this age border collies typically begin to slow down when it comes to gaining weight but will still have a good appetite because of their high amounts of energy. 

However, it is important not to overfeed your dog, so it does not become overweight. Your Border Collie’s baby teeth will begin transitioning to adult teeth at this age. Your dog will likely weigh somewhere between 12 and 26 pounds, depending on its gender.

6-16 Months of Age

At 7 months of age, your male Border Collie will become sexually mature, and a female may go into heat around 6 months old. At this age, you should consider speaking to your dog’s veterinarian about getting your dog spayed or neutered. 

You will notice that your dog will bond with you and your family by this point and will recognize you as the leader of their pack and your family as the rest of the pack. Your dog will have lots of energy at this age, and you need to make time for them to get the exercise they need to thrive.

16-36 Months of Age 

Your Border Collie will be highly active during this stage of their life. By 24 months old, your female Border Collie is considered an adult, and your male is regarded as an adult at 36 months old. 

Your dog will reach their adult weight by the time they are 18 months old, which can be anywhere between 26 and 52 pounds, depending on its gender. Most Border Collies are medium-sized dogs. A male will reach a maximum height of 22 inches, and a female will reach a maximum height of 20 inches.

How Active Are Border Collies Compared to Other Breeds?

Border Collie dogs are high-energy, intelligent, fun, and intense compared to other dog breeds. Due to their ancestry as herding dogs, it is natural for Border Collies to be more energetic than most breeds and have an intense activity level. However, other dog breeds behave very similarly to Border Collie dogs. These breeds include:

  • Australian Shepherd
  • Bearded Collie
  • German Shepherd
  • Icelandic Sheepdog
  • Miniature American Shepherd
  • Old English Sheepdog
  • Pembroke Welsh Corgi
  • Polish Lowland Sheepdog
  • Great Pyrenees
  • Briard
  • Puli
  • Cardigan Welsh Corgi
  • Collie
  • Shetland Sheepdog
  • Belgian Malinois
  • Australian Cattle Dog

These breeds are energetic and intelligent, active dog breeds that require lots of mental and physical exercise. Most of these breeds are herding dogs from icy regions. Herding dogs, like Border Collies, have a natural-born instinct to be on the go constantly, are highly trainable, have a sensitive personality, and are loyal to their owners.

Your Border Collie will display a much calmer attitude once they reach the age of 6, becoming more mature at that age. Your dog can become calmer at a younger age, but Border Collies generally take a few years to calm down.

When Do Border Collies Calm Down After Being Neutered/Spayed?

Border Collies do calm down after being neutered or spayed, showing almost immediately. Your male dog will become less aggressive, and your female will no longer go into heat. 

However, neutering and spaying your Border Collie does not entirely make them calm. Since this breed is hyperactive by nature, your Border Collie will still be energetic and will still need to have a lot of activity in their lives. 

How Do I Get My Border Collie to Settle?

To help your Border Collie settle, you will need to incorporate a regular exercise schedule into their daily life. In addition, you can also help your Border Collie settle down by giving it lots of attention, agility training, mental stimulation, and you can give it a calming aid. 

The more active your dog is, the more energy your Border Collie will be able to let out so it can become calmer and settle down.

How Long Does the Puppy Stage Last for Border Collies?

Border Collies are the size of a puppy until they reach between 8 and 12 months of age. Once they get to that point, they will lose their puppy fur, go full size, and become sexually mature. Even though your Border Collie will appear to be a fully grown dog, they will still behave like a puppy until about 2 or 3 years of age due to their energetic nature.

Are There Any Calm Border Collies?

Are Female Border Collies Calmer Than Male border collies?

There is not much of a difference between males and females when it comes to calm behavior. Both genders are full of energy, playful, and love attention. However, male dogs of this breed are more stubborn and like to bond with family members.
