Puppy Weight Calculator by Breed, Age, and Parent Size
Estimate your puppy's likely adult weight range from age, current weight, breed, sex, and optional parent weights. Use the result beside breed charts and body-condition checks, not as a fixed medical target.
Live puppy estimate
Estimate adult size from today's weigh-in
Start with age and current weight, then add breed, sex, and parent weights when you know them.
After the estimate, compare it with a breed weight chart, the matching dog size chart, and the body condition guide.
Planning tool only - not veterinary advice.
How to read the result
Range
Use a band, not one number
Puppies grow at different speeds by breed and frame. The range is meant to guide follow-up checks, not replace veterinary advice.
Context
Compare breed and size charts
Breed pages give adult ranges and monthly checkpoints, while size charts show the broader toy-to-giant growth pattern.
Recheck
Update the estimate over time
Rerun the calculator after fresh weigh-ins, food changes, growth spurts, or changes in activity and body condition.
