Puppy Weight Calculator: Height and Weight Predictions for Every Breed (with Chart)

Wondering how big your puppy will get? Our puppy weight calculator predicts your dog’s adult weight and height. The calculations are based on the American Kennel Club’s database of adult dog weights and heights. Fill in your puppy’s current age and weight details below.

Note: please don’t feed your dog more or less based on the results. For that advice, consult your veterinarian.

If you like our calculator and you’re interested in learning everything you need to know about puppy weight, including which factors influence it, weights for various breeds, and checking out our custom puppy growth chart, then read on for even more information about puppy weight. Visit this post for more information about how heavy your dog should be (and what to do if your dog is overweight).

Factors that Influence a Puppy’s Weight

As you can imagine, many factors can influence a dog’s weight. Some are genetic and others are environmental.

First, as we mentioned, you can look at your puppy’s parents for a clue. While it’s not a surefire method, if both parents are approximately the same size and weight, there’s a good chance that your pup will grow up to be about the same size. Many times, of course, you won’t be able to see both parents (or even one parent), so this makes it more of a guessing game. Even if the puppy’s mother is, say, 30 lbs, that doesn’t mean that his father wasn’t 20 lbs or 50 lbs.

Sex can also make a difference when it comes to puppy weight. Male dogs of each breed tend to be larger and heavier than female dogs of the same breed. If you are getting a male puppy, then, it’s likely that if the father is the same breed, your pup will be a bit bigger than his mother. A female puppy might end up being the same size as her mother, assuming the father wasn’t much bigger.

While neutering won’t change overall puppy weight on its own, it can make the dog more likely to end up overweight if you don’t modify his diet. The reduction in sex hormones makes your puppy’s energy needs go down, so it’s often necessary to feed him less. You should not change his diet drastically without speaking to your veterinarian, though; keep in mind that if you have him neutered before he’s a year old, he’s still growing and needs more calories than an adult dog of the same size.

And on that note, diet and exercise will play a role in how much your puppy weighs once he’s an adult. Just like humans, dogs can become overweight or obese. And just like humans, there are serious health effects from obesity in dogs. So be sure to feed your dog a healthy diet and help him get the exercise he needs for good health.

How Big Will My Puppy Get? Average Weights for Various Breeds

If you know your puppy’s breed (or breeds, in the case of a mixed-breed dog), you might be able to guess what his adult weight will be. The puppy calculator takes breed into consideration, but here are a few examples of what you might expect depending on the breed of your pup. Remember that where there is a range, the females will generally be on the smaller end and the males on the larger end, but there is a lot of overlap between individual dogs.

Toy Breeds

  • Chihuahuas will generally not exceed 6 lbs. 1For more, see our Chihuahua Growth Chart
  • Maltese will usually be under 7 lbs. 2
  • Toy Poodles will be between 4 and 6 lbs. 3

Small Breeds

  • Standard Dachshunds will grow to be between 16 and 32 lbs. 4
  • French Bulldogs will be under 28 lbs. 5
  • Pugs will usually be between 14 and 18 lbs. 6

Medium Breeds

  • Border Collies will often grow to be 30 to 55 lbs. 7

How Fast Will My Puppy Gain Weight?

The speed at which your puppy will reach his adult weight depends on his overall size. In general, toy and small breeds will grow more quickly than large and giant breeds. Toy breeds might reach their adult weight at as young as 8 months, while the largest of the giant breeds will continue growing until they are 2 or 3 years old. Small, medium, and large breeds will fall in line along that spectrum.

Using a puppy growth chart like these from the Waltham Petcare Science Institute can help you determine whether your pup is at the right weight for his breed and size. Keep in mind, however, that these weight charts are good as a rule of thumb but that there will be some individual variance. Your vet can help you decide whether your puppy is underweight, overweight, or just right.

As he becomes an adult, you can use the method where you feel his ribs. For most dogs, you should be able to easily feel his ribs without pressing inward; you should not see his ribs. Some breeds tend to be leaner or heavier, however, so again, this is something your veterinarian should help you determine.

If you want to guess at how much your puppy will weigh as an adult, you can double what he weighs or weighed at 4 months of age. This is a good estimate for medium and large dogs, but it doesn’t work well with very small or giant breeds, as they grow more quickly or slowly than average. It also can’t take into consideration the possibility that your dog may become overweight or obese. Still, it will give you a good ballpark estimate if you are curious.

As with everything else pertaining to your puppy, keep in mind that he is an individual. Even littermates might end up not weighing the same as adults, so keep an eye on how your pup is growing with the help of your veterinarian, who will see him several times over the course of his first year and then annually after that. Your vet is your best source of information pertaining to your specific puppy and what he should weigh.
