Puppy weight calculator
Get a rough idea of how big your puppy might grow, and see where they are on a typical growth curve.
Labrador Retriever adults usually weigh
about 55 to 80 lb
At 12 weeks, Labrador Retriever puppies are typically about 26% of their adult weight, with most of their growing still ahead.
Estimates vary, and every puppy grows at their own pace. Ask your vet about your puppy’s growth.

How this works
Puppies grow fastest in their first months, then slow down as they near adult size. Small dogs are usually close to adult weight by about 10 to 12 months, medium dogs by about 12, large dogs by 12 to 16 and giant dogs by 18 to 24.
For a mixed or unknown breed, we divide today's weight by the share of adult weight a puppy of that size typically has at this age, then give a range about 10% either side.
For a breed we know, we show that breed's usual adult weight and how far along its typical growth curve a puppy of this age is.

Common questions
How accurate is a puppy weight calculator?
It gives a rough idea, not a promise. Parentage and the pace of growth vary a lot from puppy to puppy, and estimates are least certain for young puppies. Ask your vet about your puppy's growth.
When do puppies stop growing?
Small dogs are usually near adult weight by about 10 to 12 months and medium dogs by about a year. Large dogs can keep filling out until 12 to 16 months, and giant dogs until 18 to 24 months.
How do I guess a mixed-breed puppy's adult size?
Choose the size you expect, then enter their age and weight. The calculator works from a typical growth curve for that size. If you know roughly how big the parents are, that can help you choose.
My puppy's dot isn't on the curve. What does that mean?
The curve is a typical pattern, and real puppies sit above and below it. It is not a measure of whether your puppy's weight is right. If you have questions about their growth, ask your vet.
How does the calculator handle mixed breeds?
Choose a named mix such as the Cavapoo, or choose "Mixed or not sure" and add up to three breeds. The adult range runs from the smallest parent's low to the largest parent's high, because puppies can take after either parent, and the estimate from today's weight uses the size of the most likely adult weight. With no breeds added, pick the size you expect.
Does Paww keep what I enter?
No. The calculator runs in your browser and does not save or send your puppy's details.
