A major idea explaining why dogs mature so quickly is one that is grounded in reproductive science. Dogs and other animals with shorter lifespans mature sexually much more quickly, enabling them to procreate and preserve the species. Similar to this, animals that have larger litters and shorter gestation times do not need to live as long to maintain the species because they can reproduce enough young in a shorter amount of time.

However, dogs eventually achieve their mature size and cease growing, just like the majority of other mammals.
Small breeds reach their peak size between 6 and 8 months of age. Large-breed dogs cease growing between 12 and 18 months, whereas medium-sized dogs stop growing at 12 months.
Puppies from large breeds take longer to mature because their larger bones require more time to develop. There is a lot of leeway, though, and some dogs stop growing considerably earlier or later than the one-year point.
Below, we’ll discuss these variations as well as other factors that affect how quickly your dog reaches adulthood.
Key Takeaways: When Do Dogs Stop Growing?
- Dogs often reach their growth plateau between the ages of 6 and 18 months. In general, tiny breeds reach their growth plateau younger than large breeds.
- The period of time during which your pup will continue to grow might be influenced by a number of things.
- The two most crucial elements, though, are probably your dog’s genes and the food you provide him.
- The size of your dog may change very little as a result of spaying and neutering. These discrepancies, meanwhile, are fundamentally insignificant and only become apparent after reviewing masses of data.
When do dogs stop growing in size?
Although there isn’t a universal cutoff point for when canines cease growing, it can vary depending on the breed, age, and health of your dog. Your dog’s growth will be finished, on average, in about 24 months.
Male dogs often grow bigger and taller than female dogs, and they also maintain their size a little longer. If your dog is a little breed, they can stop growing before they turn a year old.
Your puppy needs a lot of energy, therefore you should give them smaller meal portions more frequently.
The growth plates of puppies close at different periods; the more nutrients your puppy needs in their diet, the closer it is to closing.
Your puppy needs the right nutrition as they grow and their bone structure develops to support healthy growth.
Puppies begin to develop their bodies and reach sexual maturity between 7 and 9 months of age. However, they will continue to fill out until they are about 18 months old.
The rate of dog growth.
Puppy breeds with larger sizes extend their growth spurt slightly. Between the ages of eight and ten months, they may go through their bulk of growth. Most puppies cease growing by nine to eleven months. 2 However, the larger breeds could still develop a little bit longer. Some canines can stop developing fully up to 24 months after they start. 3
The size of your puppy’s ears and paws may not accurately predict how big he will become if he is still growing. These are not very trustworthy indicators. Instead, consider how big his parents or the siblings from a previous litter were. 4 Consult your veterinarian if you don’t have access to the parents or siblings.
It’s crucial to keep in mind that your puppy should continue to consume puppy food made specifically for that stage of his development as long as he is growing. A developing dog can create muscle and bone with the aid of fatty acids, calories, and protein included in puppy chow. 5
Puppy growth is rapid. They appear to be young adult dogs poised to take on the world one day and incredibly little the next. Play a lot with your puppy and always remember to enjoy your time with your furry best friend. (And don’t forget to snap tons of photos!)
What impacts a dog’s development?
If a young puppy has recently joined your pack, you probably have concerns about how her first year or so will be from a developmental standpoint. When will her growth stop? What exactly do those large paws signify? The solutions are available from Dr. Matthew Rooney, owner of Aspen Meadow Veterinary Specialists in Longmont, Colorado, and a board-certified specialist in surgery, as well as Dr. Susan O’Bell, a primary care veterinarian at Angell Animal Medical Center in Boston.
When Do Dogs Stop Growing and How Big Will My Puppy Get?
The specialists advise that most dogs’ growth plates close between the ages of 9 and 11 months. By then, you ought to have a fair idea of your dog’s final height and length, with big breeds continuing to grow until they are just over a year old, according to O’Bell. Rooney claims that smaller dogs take between six and eight months to achieve their maximum size.
“For the first one to two years of their lives, many medium and large breed dogs still have a “juvenile” aspect, but O’Bell notes that they aren’t technically still growing. Therefore, even though your dog’s demeanor and behavior can still seem young and their features occasionally still have that “Once your dog reaches the age of two, it should stop growing, giving off the puppy look (characterized by a soft coat of hair, rounded facial features and ears, and a narrower chest).
According to Rooney, you can predict the size of your dog if you know the breed or, even better, the parents of the puppy. Otherwise, it can be difficult. Your dog’s siblings are one of the best indicators of eventual height, according to O’Bell. You can get an idea of your dog’s potential size by looking at a prior litter from the same sire and dam “She adds that while there are some basic ranges for purebreds, your dog’s final size shouldn’t come as a great shock.
Unfortunately, pet owners rarely provide information on a dog’s size beyond remarking on the size of a puppy’s paws and ears. “We frequently remark on how huge a puppy’s paws or ears are, but O’Bell claims that these features are not accurate predictors of size. Rooney concurs that while a puppy may have ears or paws that, at the time, seem too big or little for their frame, they do not predict how big the puppy will eventually grow to be.
What are Some Common Conditions to be Aware of in Growing Dogs?
“Orthopedic issues are the most prevalent ones. Larger dogs are more likely to experience issues with their elbows, shoulders, hips, and other joints (50 pounds or more). According to Rooney, very little dogs may experience problems with their hips or knees, yet most growing canines won’t be impacted by these disorders.
Panosteitis, a painful but transient bone inflammation that can plague young dogs, is typically treated with medicines, according to O’Bell. Hypertrophic osteodystrophy, a painful swelling of the growth plates in the legs that frequently goes hand in hand with a fever, can occasionally affect large and giant breeds. According to her, the condition normally gets better on its own.
Hip dysplasia, which occurs when the ball and socket of the hip joint are not properly aligned, and osteochondrosis are a few inherited and congenital diseases (abnormal development of cartilage in the joints). According to O’Bell, surgery may be required in some cases to treat these disorders. According to the American Animal Hospital Association, large breeds including German Shepherds, Labradors, and St. Bernards are among those who are susceptible to these illnesses. Contact your veterinarian or a surgical specialist if you see your dog limping or notice that one of its legs looks to be slightly bent or slanted.
Do Dogs Experience Growing Pains?
According to O’Bell, puppies don’t appear to go through any developing difficulties. Young dogs, however, may exhibit indications of certain orthopedic diseases, such as those mentioned above, such as limping, an irregular gait or stance, or a reluctance to engage in routine activities. Around the impacted areas, there may occasionally be heat, edema, and/or pain. She adds that a fever, which can accompany several inflammatory disorders, can cause your dog to become lethargic and lose her appetite.
She also mentions that pups tend to have higher levels of energy than older dogs and may be more vulnerable to minor wounds from rough play, which can lead to short-term discomfort.
Are Care Requirements Different for a Growing Dog?
According to O’Bell, all puppies should visit their veterinarian on a regular basis, typically three or four times in the first year of life. During these appointments, your veterinarian will evaluate your puppy’s development, including weight gain and overall health. Rooney advises using common sense when keeping an eye on the health of your young dog. Pay attention to her routine, discuss any worries you have with your veterinarian, and keep an eye out for any symptoms that appear out of the ordinary.
Rooney advises choosing higher-protein dog foods to support your puppy’s growth from the standpoint of diet. Large-breed puppy foods are especially beneficial for large-breed puppies because they slow down the excessively quick growth that raises the likelihood of orthopedic problems. According to the doctors, you may customize your puppy’s food with the advice of your veterinarian to ensure that she is gaining adequate weight and getting the right kinds of nutrients. Young dogs require a suitable balance of vitamins and minerals, as well as more fat than older dogs and appropriate protein to support their growth and development. “If you have concerns about choosing the best diet, your veterinarian is a great resource, according to O’Bell.
Puppies should engage in at least an hour of moderate activity each day for exercise, but as anybody who has reared one or more puppies will attest, the ideal amount of exercise can vary. Your dog might only be interested in or able to play for a short while before taking a nap, depending on her breed and age. Some puppies need to be stimulated for longer lengths of time.
Young dogs may not actually be at risk from vigorous exercise, according to O’Bell, but she does suggest caution, especially in the case of large breeds and those who may be predisposed to diseases like hip dysplasia. “She adds that while they are still growing, we wouldn’t want to harm their growth plates.
Which dog won’t develop?
Maltese dogs are indeed diminutive. They grow to a maximum weight of seven pounds and a maximum height of seven to nine inches. Maltese dogs will make you happy throughout their entire lives and have expressive faces.
Is a dog still a puppy at the age of two?
Your pet is special, that much is obvious. Although there is a broad timeframe for puppy development, if your puppy doesn’t progress as quickly as its littermates, don’t worry.
But it’s not like kids suddenly become adults the morning of their first birthday! Puppy maturation is actually a process that differs from dog to dog based on factors including size, breed, socialization, and more.
What is a puppy’s most challenging age?
At Jenna Lee Designer Doodles, we grow doodle litters from birth to 8 weeks of age. But we also routinely teach particular puppies for varying amounts of time, so we are well versed in the different phases of a puppy’s development! We invited our trainers to weigh in based on their professional experience so that we could publish this post.
We polled several of our previous puppy parents as well to get a sense of what the typical owner considers to be the most challenging time. And this is what we discovered:
Although there is some variation in the responses, we generally discovered that the majority of them fell into one of two categories:
About 50% of owners and trainers picked 3 to 4 months as the most challenging age, citing nipping as the greatest challenge at this stage.
The roughest age was chosen by 35% of owners and trainers, who cited new challenging behaviors brought on by their puppy’s now-larger size, like pulling on the leash or counter-surfing.
Is a dog that is a year old a puppy?
Puppies continue to grow in height and size while their bones are still forming, which takes anywhere between 6 and 24 months. Although all puppies are officially classified as adult dogs once they reach the age of one year, this growth occurs before this point. How tall they will grow to be as adults depends on how their skeleton develops.
According to Dr. Jerry Klein, DVM, Chief Veterinary Officer at the AKC, the long bones in a puppy’s legs develop from two different locations known as growth plates.
When new tissue is forming during the puppy stage, the growth plates are somewhat malleable and mushy.
The new tissue that forms as your dog grows hardens into bone. “The growth plates are considered to have ‘closed,’ which denotes that they have stopped growing and the bone has reached its full size, according to Dr. Klein, when they have ceased to produce new tissue and have entirely calcified.
Remember that your puppy will continue to gain fat and muscle long after the bones have finished growing, just like an adult human does.
Are we parents to our dogs?
In the 30,000 years that people and dogs have coexisted, dogs have only grown in popularity and adoration as pets. Today, approximately 50% of American families have dogs.
Dogs certainly act as though they love us back, as seen by the way they beat their tails, jump onto our laps, and grab our pillows. Can we ever be certain, though, given dogs can’t tell us what’s going on inside their furry heads?
In reality, absolutely. We are beginning to have a clearer understanding of what is going on within the canine cranium as a result of recent advancements in brain imaging technologies.
Yes, that’s correct—scientists are investigating dog brains. And the study’ findings are good news for all dog owners: Dogs not only appear to love us back, but they also regard us as members of their family. In terms of affection, protection, and everything in between, it appears that dogs depend more on people than they do their own species.
The most recent neuroimaging study on olfactory processing in the canine brain provides the most conclusive proof that dogs are utterly committed to people. Emory University animal cognition researchers trained canines to remain still in an MRI machine while they measured canine neural responses to both familiar and unfamiliar canine and human odors. Dogs use their noses to navigate the world, so studying how they process smell might reveal a lot about how they behave in social situations.
The caudate nucleus, known as the brain’s “reward center,” was discovered to be activated by the smell of dog owners. Dogs actually gave the scent of people the highest priority among all other scents to take in.
These findings are consistent with other canine neuroimaging studies. Canine brain activity in response to various human and canine sounds, such as voices, barks, and the meaningful grunts and sighs both species generate, was examined by researchers at Eotvos Lorand University in Budapest. Our understanding of what transpires inside canine brains when humans make noise was lacking prior to this investigation.
The study found a number of unexpected results, including striking parallels between how human and canine brains absorb emotionally charged vocal sounds. Researchers discovered that both animals’ auditory cortexes are particularly activated by pleasant noises. This similarity highlights the special, effective communication system that underlies the link between humans and dogs.
In other words, dogs are biologically designed to notice minor changes in human mood, despite the fact that they only appear to do so.
The most modern neuroscience is supported by behavioral studies. Dogs engage with their human caretakers in a similar fashion to how children do with their parents, claims Andics. Just like disturbed children rush to their parents, dogs will run to their owners when they are terrified or anxious. Contrary to most domesticated animals, cats and horses will flee when they are frightened.
Dogs are the only non-primate animal that direct its gaze directly at a person. Andics and other researchers made this discovery approximately ten years ago while researching the domestication of wolves, which they hypothesized would also exhibit this feature. To raise wolves like dogs was their goal. This is a characteristic of dogs and humans only. Dogs look people in the eye, but not their actual dog parents.
Dogs need their owners significantly more than other types of pets do, according to Andics.
Scientists have also viewed the relationship between dogs and people from the other side. It turns out that dogs feel very strongly about people. Researchers from Massachusetts General Hospital examined how the brain reacts to images of dogs and kids in a study that was published in PLOS One in October. Women who have owned pets and children for at least two years were study participants. Brain areas linked to emotion, reward, affiliation, visual processing, and social interaction were active in response to both types of photographs. In essence, we are equally happy with our furry and (usually) non-furry family members.
Dog lovers have made a few prominent mistakes when reading dogs’ facial expressions, such as supposing that the frequently observed hangdog look denotes guilt, an emotion that, according to the majority of behavior specialists, calls for a complex sense of self that dogs undoubtedly lack.
However, just as with family, our gut feelings about how dogs behave are frequently accurate.
According to Laurie Santos, the director of Yale’s Canine Cognition Center, “sometimes our intuition about what’s going on inside dogs’ heads is dead-right.” According to studies, dogs are asking for our assistance, which is distinct from even their closest cousins, wolves.
A dog’s glum expression may not always be indicative of a specific want or concern. But we can take comfort in the knowledge that our pets love us just as much—if not more—than we had hoped. They view us as family even though they aren’t actual children. How about us? They will always remain our infants, I suppose.
