Puppy growth is not linear. Breed mix, parent size, nutrition and health can move the result considerably.
About the ±15% range: this is an industry rule-of-thumb used for planning, not a measured accuracy figure from our own testing. Estimates tend to be tighter for purebred puppies with known parent weights, and wider for mixed-breed, giant, and toy puppies. Treat every result as a planning estimate — not a guarantee — and confirm your puppy’s growth plan with your veterinarian.
