Puppy Weight Calculator & Growth Chart

Why Our Puppy Weight Calculator Is More Accurate

Most puppy calculators use simple linear math, which can overestimate young puppies and create unrealistic growth expectations.

Our calculator uses:

• A curved growth multiplier

• Gradual normalization to full adult size by 52 weeks
