Puppies are adorable, but it’s important to remember that all canines eventually reach adulthood and their full size. At what age do dogs stop growing, if ever? How large do you anticipate your puppy to get?
Most canines reach their maximum size between 6 and 18 months. However, this number may vary based on specifics like your dog’s breed and gender. Here are some generalizations and rules of thumb to help you estimate your dog’s final adult size and determine at what age do puppies stop growing. Let’s zero in on the big dogs first.
RAISING LARGE VS SMALL DOG BREEDS
Which Are The Signs That Indicate That Your Puppy Is Fully-Grown?
Typically, a dog’s growth spurt ends anywhere from 6 months to 18 months, while some puppies keep growing up to 24 months. While all dogs develop at about the same pace, toy, and toy-sized breeds mature far more quickly than their bigger counterparts. This is because larger-boned and jointer dogs take longer to mature physically.
It takes the longest for giant breeds like Mastiffs, Great Pyrenees, Saint Bernards, and Newfoundlands to mature. Even though giant breeds like the Great Dane attain full maturity by the time they are 18 months old, they continue to gain muscle and reach their full weight once they are 2 or 3 years old.
At What Age Do Dogs Stop Growing?
Small dogs mature rapidly. They reach their full adult size in around half the time it takes their bigger counterparts. The skeletal systems of small-breed dogs like Boston Terriers, Jack Russell Terriers, Chihuahuas, and Pugs mature at around six to eight months of age and continue to fill out until around twelve months of age. Due to their slower rate of aging, little breed dogs also tend to live longer than their bigger canine counterparts.
The average growth rate of a medium-sized breed puppy is higher than that of a small-sized one. Between 12 and 15, your medium-sized dog will attain full maturity. Their growth spurt begins at the 15-month mark, and they continue to put on weight even as they approach the 18-month mark. As examples of medium-sized dog breeds, we may name the Airedale Terrier, American Pit Bull Terrier, Border Collie, and Standard Poodle.
Two types of dogs fall within the huge breed category: giant breeds and large breeds. Large-breed dogs typically mature at over 50 pounds (about 23 kilograms). Large-breed dogs take much longer to mature than smaller-breed dogs, with an average growing period of 12 to 18 months and maturity between 18 and 24 months.
The Labrador Retriever, the German Shepherd, and the Weimaraner are a few examples of common large dog breeds.
Larger canines that typically weigh more than 45 kilograms (99.9 pounds) are classified as enormous breeds (99lb). The longest maturation time is for them. It may take certain gigantic breeds up to three years of age to reach their full adult weight, and it usually takes at least 18 months for the fundamental foundation to develop.
These dogs also tend to age more rapidly than toys or tiny breeds. The Mastiff and the Dogue de Bordeaux have a relatively short life expectancy of 7–8 years.

How much larger will a dog be at 6 months?
The first trimester of your puppy’s life is crucial to his or her development. Puppies, however, continue to grow and develop until they reach their full adult size. Compared to bigger dog breeds, the growth of toy and tiny dog breeds is almost complete by 6 months. After 6 months, a puppy of a medium- to large-sized breed may weigh around two-thirds of his adult body mass. Puppies of large breeds, on the other hand, often weigh only around half as much as they would as adults at this age.
Can You Estimate How Large Your Puppy Will Get?
Your puppy’s expected mature size may be predicted in a few different ways. Examining the size of your puppy’s paws is one technique that could be more reliable since it is based on a misconception. If you know your puppy’s breed, you can more accurately predict its adult size.
If you own a purebred dog, you will find breed standards very beneficial. If that’s the case, you may also use a puppy weight calculator that considers breed standards to know how large your dog will grow.
It’s more difficult to predict how big a mixed-breed puppy will grow. If you are familiar with the breeds and sizes of your dog’s parents, you may have a better idea of what to expect from your pup. If that isn’t feasible, you may get a good approximation of his complete size based on his presumed breed.
Why does a puppy stop growing?
It might be unsettling when your puppy isn’t developing normally or seems too little for their age. In certain cases, your dog’s development may just cease on its own for no apparent reason. This might be due to anything from genetics to intestinal worms. Here, we’ll inspect a few of the most prevalent causes of canine development retardation.
There is evidence that hookworm and roundworm infections may cause growth retardation in puppies. An extensive worm infestation may stunt puppy development because the worms consume so much of the puppy’s calories. Hair loss, diarrhea, and a large waistline are all symptoms of worm infestation.
Stunted growth in dogs is common, and malnutrition is a major contributor. Puppies need to consume well-balanced meals so that their body tissues develop normally. Make sure the puppies have enough to eat so that they may build strong bones, muscles, and tissues. Likewise, don’t overfeed your dog or give them supplements while they’re still developing; doing any of these things might have negative repercussions.
What makes your dog get to the appropriate size?
Getting your dog to eat a balanced meal is the greatest way to guarantee he develops into a healthy adult. Overfeeding a puppy may cause bone and joint issues, including osteochondritis dissecans (OCD) and panosteitis, so keeping him on the thin side is important. It’s been said that large-breed pups, in particular, shouldn’t be given high-protein diets. The link between this and joint disease has been debunked, although excess calories are a real issue.
When shopping for dry food for your dog, try to choose options with at least 26% protein. Raw puppy chow should include at least 14% protein and no more than 10% fat, as fed if you plan on feeding your dog this way (which we highly suggest). The best way to ensure your puppy has a healthy start in life is to feed them a commercial raw diet of high quality. Finally, provide your dog with a balance of brief bursts of activity and relaxation. Because of this, he will reach his maximum height and weight potential.
What Could Be Causing My Dog’s Failure to Grow?
Hookworms and roundworms are the most prevalent causes of stunted growth in young pups. Your puppy may get these parasites through his mother or the environment, which are quite prevalent in the United States.
It’s easy for a veterinarian to do tests and determine whether or not your puppy has parasites. But keep in mind that they might suggest poisonous medications for your dog. Worms may be treated organically, and a raw food diet for your dog is one way to ensure he or she never gets them.

When do dogs cease maturing, then? Estimating your dog’s future size based on his breed is the most reliable method for determining at what age do puppies stop growing. Using a puppy weight calculator, you may obtain a rough estimate of your purebred dog’s adult size. Feeding your dog a raw, whole-food diet is the greatest way to ensure he reaches his maximum potential in size. Your puppy may have worms or parasites if he isn’t developing despite a healthy diet.
