Puppy Growth Chart
by breed size.
Pick your puppy's adult size category and see the expected weight range at every milestone from 8 weeks through 18 months. Drop in a current weight and the tool tells you whether you're tracking inside the range or drifting. Built so you can answer the "is she tracking?" question at the vet.

How it works
Pick a size,
read the curve.
AKC size categories cluster breeds by adult weight. Within a category, the puppy growth curve follows a predictable shape. The tool plots that curve for your puppy from DOB.
See the milestone chart
Projected weight range at 8, 12, 16 weeks, 6 months, 9 months, 12 months, and 18 months. Each row pegged to the calendar date so you know exactly when to weigh.
Check tracking
Drop in the current weight if you have one. The tool tells you whether the puppy is inside the expected range, drifting low, or drifting high.
Once you've seen the curve
The free chart is the reference.
The paid tracker is the weekly log.
The free tool gives you the curve. To log 24 weekly weigh-ins with auto-calculated weekly gain and percent gain, the Weight Tracker is a $4.99 Excel workbook. For the full first-16-weeks package (vaccination schedule, growth chart, weight tracker, checklist, socialization, more), the New Puppy Kit bundles the lot at $37.
Common questions
A few things people
ask about puppy growth.
The ranges derive from Royal Canin's published puppy growth-curve model (the "percent of adult weight at each milestone age" table for Small, Medium, Large, and Giant size classes) applied to standard AKC adult-weight buckets. They're a starting point, not a breed-specific lookup — individual breeds vary 10 to 20 percent within a size class. Use the tool to spot major curve drift early; for tighter precision, look up your specific breed's growth standard or talk to your vet.
By adult weight: Toy is under 12 lbs (Chihuahua, Yorkie, Pomeranian). Small is 12 to 25 lbs (Beagle, Cocker Spaniel, Mini Schnauzer). Medium is 25 to 55 lbs (Border Collie, Bulldog, Australian Shepherd). Large is 55 to 100 lbs (Labrador, German Shepherd, Boxer). Giant is over 100 lbs (Great Dane, Mastiff, Saint Bernard).
They mean: is the puppy gaining weight at the rate expected for the breed and size, on the curve, not above or below it. Healthy growth is steady week-over-week gain that lands inside the expected range. Major drift (off the bottom or top of the range for the age) is worth a conversation; small fluctuations are normal.
Small deviations (within 10 to 15 percent of the range) are usually fine and reflect individual variation or recent meal timing. Bigger gaps may signal under- or over-feeding, parasites, or a breed that's just on the smaller or larger end of its category. Always bring it up at the next vet visit, especially if the drift is accelerating week-over-week.
Steady weight loss, plateaued growth for more than 2 weeks, or visible ribs/hip bones in a young puppy all warrant a same-week vet call. For the opposite end, overweight puppies are a long-term joint and longevity risk, especially in large and giant breeds where excess weight during growth correlates with hip dysplasia.
Normal. Most puppies have a major growth phase between weeks 8 and 16 (the doubling-in-size window), then slow gain until they hit their adult weight (~12 months for small/medium, ~18-24 months for large/giant). Plateaus of 1 to 2 weeks within an otherwise rising curve are normal and not a cause for concern.
