Puppy Weight Calculator: How Big Will Your Dog Get? (2023)

For:Sharon Diana

Why Use a Puppy Weight Calculator? The simple answer is that it helps predict how much your cute little pup will weigh as an adult dog. Aside from helping you plan and prepare better, aren't you a little curious about how big the little one is going to be?

Puppy Weight Calculator: How Big Will Your Dog Get? (1)

If you know the breed you might know what to expect (roughly), but there is so much variation in size that it's hard to tell at times. And if you don't know the breed or it's a mixed breed, you might be completely in the dark.

For this reason, using a puppy weight calculator can help you estimate how much your puppy will weigh when he's fully grown.

At this point you may be wondering if puppy weight calculators are accurate.

The answer is that they can be, but it depends on the formula used and the puppy's growth rate. All puppies grow at different rates; However, the breed's size is a good indicator of how much weight they will gain and how quickly.

For this reason, our puppy weight calculator uses the growth rate of each breed size to estimate adult weight. A puppy weight calculator that doesn't use breed size to predict final weight can be seriously wrong.

breed size classes

Dog breeds are generally divided into five categories based on size. These are; Toys, small, medium, large and huge. It's not an exact science and many races will overlap. In general, however, the smaller the breed, the faster they grow and the sooner they reach maturity. The larger breeds mature more slowly and reach sexual maturity much later.

  • Toys = up to 12 pounds
  • Small = 12 - 25 pounds
  • Medium = 25 - 50 pounds
  • Large = 50 - 100 pounds
  • giant = over 100 pounds

If you have a mixed breed dog or are unsure what breed size your pup falls into, please check your pup's current age and weight using ourWeight charts for puppies.

Toy breeds grow faster than larger dogs, reaching adult weight by eight to nine months. On average, they gain 5-10% of their body weight daily, which equates to 1 to 5 ounces per week.

Most of their growth occurs between 0 and 11 weeks.
