When Do Dogs Stop Growing

On average, dogs stop growing in size around 1 to 2 years of age. However, smaller breeds tend to mature faster than larger ones and can reach full size earlier. Factors such as diet and exercise also play an important role in how quickly a pup grows.

In this article, we will explore the average age when dogs stop growing, the factors that can affect a dog’s growth rate, and how to ensure proper nutrition for your growing pup. Finally, we’ll take a look at the different growth rates of some popular breeds so you can determine if your pup has stopped growing. So, let’s get started!


The General Growth Timeline of Dogs: Stages and Ages

The general growth timeline of dogs can be divided into several stages, each with its own age range and developmental milestones. Here is an overview of the general growth timeline of dogs:

  • Neonatal Stage (0-2 weeks old): During the neonatal stage, puppies are completely dependent on their mother for nutrition and care. They are born blind, deaf, and unable to regulate their own body temperature.
  • Transitional Stage (2-3 weeks old): Puppies start to become more active and aware of their surroundings during the transitional stage. They begin to open their eyes, and their sense of hearing develops.
  • Socialization Period (4 Weeks Until 12 Weeks): As pups near 4 weeks old, a major focus of their physical growth turns to exercising the body but also stimulating their minds through playtime, exploration, and learning the basics of commands like sit or stay.
  • Juvenile Stage (3 Months Until 6 Months): During the juvenile stage, puppies become more independent and start to explore their surroundings. They may become more curious and begin to test their boundaries.
  • Adolescent Stage (6-18 months old): The adolescent stage is a time of rapid growth and development. Puppies start to reach their full size and begin to develop adult behaviors. They may also experience a surge in energy and become more difficult to train.

It’s important to note that the ages and stages listed above are general guidelines, and individual dogs may develop at different rates. It’s also important to provide proper nutrition, exercise, and veterinary care throughout a dog’s life to support its growth and development.

Average Age When Dogs Stop Growing

Did you know that adult dogs generally stop growing by the time they turn one year old? While individual breeds may mature at different rates, most pups reach their full adult size within 12 to 18 months — small breeds often do sooner, while larger breeds take a bit longer.

Size isn’t the only factor to consider when it comes to determining when your dog will stop growing; other impacts such as nutrition and general health can also play a role.

Don’t let these factors get in the way of enjoying your puppy’s growth journey. Take advantage of quality nutrition tips and regular health checks to give them the best start and keep them strong throughout their life.

6 Factors that Affect a Dog’s Growth Rate

There are a number of factors that can affect a dog’s growth rate and the age when it will reach its full size. Understanding these factors can help you determine when your pup will stop growing and ensure that it receives proper nutrition throughout its life. Some of the most common factors include:



Dog owners are naturally concerned about the growth rate of their canine companions. While genetics play a part in how quickly a dog grows, it is important to recognize that nutrition is also an influential factor when it comes to pup size and development.

Feeding your pup the proper amounts of proteins, carbohydrates, and fats will ensure that they have all the energy necessary to grow up strong. Not only that, but it will supply them with essential vitamins and minerals needed for healthy bones and muscles. Don’t forget that providing plenty of fresh water is just as important as food when helping your pup reach its full growth potential!




Genetics have a major impact on the growth rate of dogs, as different breeds have been selectively bred for generations to have unique characteristics. The size and shape of their bones are crucial, as this will determine their overall body shape when they mature.

Some breeds develop faster than others, and many larger breeds take longer to mature – sometimes up to three years before reaching their full adult weight and appearance. Genetics are also responsible for differences in coat length, coloration, and facial structure, all of which can affect a dog’s growth rate.




Exercise helps ensure that they maintain their optimal growth rate, so it’s important to provide them with the right amount of play and physical activities. Not only does exercise have a positive effect on their physical and mental health, but they also benefit from having the opportunity to release some of their energy and get some needed fresh air.

Furthermore, it can help prevent any health problems that can arise due to a lack of physical activity, such as obesity or joint pain. There are many different ways to exercise your dog, depending on the size and breed of your pup. Taking them for walks or letting them run around in a fenced-in area are great ways to get some physical activity. Doing agility courses is another excellent and fun way to keep your pup active and healthy.



Health Conditions

Health conditions can play a major role in determining the growth rate of a dog. Dogs may be born with physical abnormalities that impede their growth, and certain environmental factors such as nutrition and exercise can have an undeniable impact on the rate at which Fido grows.

Genetics also seems to be a large contributing factor to growth, as some dogs will simply naturally reach a mature size much faster than others. Infections from viruses or bacteria can slow down development and cause delayed growth in your pup, but fortunately, many of these conditions are treatable by veterinarians if spotted early enough.

Health Conditions



Knowing the breed of your dog is an essential part of understanding its growth rate and overall care needs. Different breeds tend to grow faster or more slowly, and some experience larger growth spurts as puppies while others have a more gradual development over time. Each breed has its own specific characteristics, temperament, and health issues that may also need to be taken into consideration when providing the best care for your pup.




The environment in which a dog is raised can also influence its growth rate. Dogs that experience frequent changes in routine and activity levels, or who are exposed to environmental stressors such as extreme temperatures, may not reach their full size as quickly as those who have more stable living conditions.



When Do Different Breeds of Dogs Stop Growing?

The age at which a dog stops growing varies from breed to breed, depending on its size and gender. Knowing when each breed typically reaches its full size can help you understand the growth rate of your pup and make sure that it is receiving proper nutrition throughout its life.

Age of Physical Maturity
Chihuahua 9-12 months
Pomeranian 10-12 months
Beagle 15 months – 2 years
Labrador Retriever 15-18 months
Bulldog 12-14 months
German Shepherd Dog 2 years
Golden Retriever 14-15 months
Yorkshire Terrier 8-10 months
Shih Tzu 10-12 months
Boxer 18-24 months
Dalmatian 2 years
Siberian Husky 18-24 months
Great Dane 18-24 months

It’s important to note that these are just average ages when dogs of these breeds typically stop growing. Individual dogs may continue to grow and develop beyond these ages, while others may stop growing earlier. It’s also important to provide proper nutrition, exercise, and veterinary care to ensure that dogs of all breeds grow and develop healthily.


How to Tell If Your Dog Has Stopped Growing

It’s important to know when your dog has stopped growing so you can take the right steps to ensure their health and well-being. Here are 5 ways to tell if your dog has stopped growing:

  • Measurements: Take regular measurements of your pup, such as height and weight, over time to check for growth patterns.
  • Teeth: Dogs usually finish teething at around 6 months of age, although this can vary greatly depending on the breed. Check for any changes in your pup’s teeth as he or she matures.
  • Coat: The texture and coloring of a dog’s coat will change with age, from soft and fluffy puppies to solid coats on adult dogs. This can be an indication that your pup has stopped growing.
  • Activity Level: As dogs get older, their activity levels tend to decrease as they reach their full size. Keep an eye out for changes in energy levels since a sudden change could mean that your pup has finished growing.
  • Behavior: If you notice your pup is acting differently in terms of behavior, it may mean that they have reached their full size and are done growing. Pay attention to any changes in personality or habits as they may indicate that your pooch is no longer growing taller or bigger!

Knowing when your pup has stopped growing is important in order to give them the best care possible throughout their lifetime – so keep an eye out for these signs!

6 Ways to Ensure Proper Nutrition for Growing Pups

Establish a Feeding Schedule

Establishing a regular feed schedule is important when it comes to ensuring proper nutrition for growing pups. Meal times should be at the same time each day, as this helps to ensure that your pup is receiving consistent nutrition.

Include High-Quality Protein Sources

As puppies grow, they require high-quality protein sources to support healthy muscle, bone, and joint development. Look for foods with whole-food ingredients like fresh meat or fish, organ meats, and eggs.

Feed the Proper Amount

Nutrition requires careful balance — both too little and too much can have negative consequences for a growing pup’s health. Talk to your veterinarian about how much food your puppy needs each day depending on their age, breed, activity level, and health concerns.

Add Supplements as Needed

There may be some circumstances where supplemental nutrients are recommended due to an underlying problem or an individual pup’s health requirements. In these cases, consult with your veterinarian to determine which supplements are right for your pup and when they should be given throughout the day.

Provide Variety in Your Pup’s Diet

Variety ensures that a puppy is getting the full range of vitamins and minerals they need while also keeping their mealtime interesting! Different proteins, as well as fruits and vegetables, should be included in a balanced diet for your pup. There are many safe and healthy fruits dogs can eat, including apples, bananas, blueberries, and watermelon (seedless). However, some fruits are not safe for your pup to eat.

Monitor Your Dog’s Weight

A puppy should never look gaunt or bloated; if you notice any changes in appearance accompanied by changes in appetite or energy levels, contact your vet immediately! Underlying medical conditions can cause major nutritional deficiencies in growing pups so monitoring weight can help ensure proper nutrition over time.


In Conclusion

it is important to understand the factors that can affect a dog’s growth rate so you can determine when your pup will reach its full size. Knowing when dogs stop growing can help you ensure proper nutrition, exercise, and veterinary care throughout your life.

Different breeds tend to grow at different rates, so research the typical growth rate of your pup’s breed to get an idea of the age when your pup may stop growing. Finally, monitor your pup’s weight and behavior for changes that might indicate they have finished their growth spurt.
