How much they eat when young
If your puppy is eating a lot and seems to be growing quickly, they are more likely to be a larger adult dog when compared to other dogs of the same breed. This isn’t to say it affects the overarching skeletal structure of the dog and that they will grow taller, for example. It pertains more to how much they will weigh as they get older which is another factor that contributes to their overall size.
On the other hand, if they seem to fill up easily and gain weight slowly, they’re more likely to be on the smaller side.
Ensuring your puppy isn’t being underfed is important, as this can actually stunt their growth and affect how big they get once they’re fully grown. Vice versa, if a dog is overfed when they’re a puppy, they can develop detrimental orthopedic conditions. It’s important to know how much to feed your puppy to avoid overfeeding or underfeeding them and the associated health complications that can come from this.
Overall, paying attention to their appetite can give you an idea of what to expect in terms of their adult size.
In general, male dogs tend to be larger than females. This difference is due to several factors, including hormones and skeletal structure. This applies to both mixed-breed and single-breed dogs.
When looking at the general range of weights for your puppy’s breed, you can expect a male dog to be closer to the upper limit and a female to be closer to the lower limit. For example, if the general weight range for a breed is 30–45 pounds, a female dog would be closer to 30 pounds, while a male dog might be closer to 45 pounds.
Predict your puppy’s size by its weight and age in weeks.

- A puppy growth calculator can do the calculations for you. Search online for a puppy growth calculator, enter your dogs age in weeks and their weight, and find out whether your dog will be small, medium, or large.
- Its important to remember that these calculations are just here to give you an estimate. Some dogs dont reach their adult size until a year and a half or more, so this calculation is not 100% accurate.

How Big Will My Puppy Be?
The adult size of your puppy ultimately depends on various factors, some of which are genetics, and some of which are environmental. But for the most part, the size of your puppy will depend on the following:
There are 5 different weight categories that your dog can fall into, which include the following:
In addition to the weight of your dog, it’s also important to be aware of how tall your dog will be in inches. Just like the 5 weight categories, a dog will also fall into one of the following 5 height categories:
Can you tell how big a puppy will get?
Determining what size your puppy will be as an adult can be difficult. While a good guess can be made by considering the average size of your dog’s breed or the size of their parents, that information may not be readily available for adopted or mixed breed pets. This is why many pet parents rely on looking at the size of their dog’s paws.
While not food proof, a puppys paws can be a good indicator of future growth spurts, especially if their paws are unusually large.
Typically, large breed dogs like labrador retrievers need bigger feet to support their heavier builds and taller heights. After all, tiny feet cannot hold up a 100-pound dog. This means that even when your big dog is a puppy, their paws will already be on the larger side in anticipation of their growth.
Similarly, if your dog is born with tiny feet, they will probably be on the smaller side as adults.
However, while paw-size can be a good indicator of whether your dog’s growth spurt is done, it doesn’t tell you how much bigger your dog will actually be. To figure out your dog’s adult size, you will need to know your dog’s current weight and their ages.
Although you can tell if you will have a large or tiny furry friend in the future by looking at your puppy paws, it is not foolproof. Some large dogs, such as collies, tend to have smaller feet compared to other dogs their size. Some small dogs, like bulldogs or terriers, have larger feet than other dogs their size.
That’s why it’s more accurate and helpful to calculate your puppy’s adult size based on their weight.
According to the Canine Journal, you can use these equations to figure out what your puppy’s adult size will be:
Medium Breeds (25-50 pounds): (weight at 14 weeks x 2) + (half of weight at 14 weeks) = adult weight
Trying to tell anything about their size too soon or too late is going to be inaccurate, and that’s not even getting into how being a mutt can complicate matters.
It can be relatively easy to guess how big a purebred puppy will grow up to be. However, it can be difficult to guess a puppys adult size if they are a mixture of different breeds or if you don’t know what breed their parents are. This is a common problem for those who adopted their puppy from a local shelter.
In this case, the canine DNA testing services available online may prove helpful to answer if, when, and do dogs stop growing. These tests do not cost too much and can help you determine the breed as well as the physical traits and temperament tied to that breed ( the American Kennel Club website is a great resource for finding out more information about every dog breed out there).
Once you know what breeds your dog is a mixture of, you can determine if their paws are too big for their bodies. If they have a parent who is a large dog and your dog has large paws, you can anticipate another growth spurt ahead. Inversely, if their parent is small and your dog’s paws look proportional to their body, then they are most likely done growing.
A puppy’s growth can be unpredictable at times. Their long bone growth plates generally stop growing (also known as “close”) between 8 to 11 months of age. So if you are looking at an older puppy of about six months, he has probably reached 75% of his adult height by then.
After these bones close, the puppys height and length stop growing. However, they may continue to get heavier because most large breed dogs who weigh more than 55 pounds do not fully develop into an adult until they are 12 months old.
If you can’t estimate your puppy’s adult size based on their paws, there are a few other ways you can determine how much bigger they have yet to grow:
Make sure you take proper care of your puppy, try to keep diseases at bay, and meet all his nutritional needs so that he may grow into the best possible version of himself. Puppy food is a must, and being sure to exercise new puppies will ensure they grow up big and strong!
