Hi Product Hunt,
I built PuppyWeightCalc to answer a common question from new puppy owners: “How big will my puppy get?”
Many existing calculators return a single number without explaining where it came from. PuppyWeightCalc instead returns an estimated range based on the puppy’s age, current weight, breed or size category, and typical growth patterns.
It includes breed-specific weight charts, male and female ranges, lb/kg support, mixed-breed inputs, and a public methodology page. The core prediction is deterministic and does not use AI.
I’d especially appreciate feedback on the clarity of the estimate and the mobile experience.

Finally a puppy weight calculator that doesn't shove a sign-up wall at you. Love that it shows the male and female ranges separately and explains how it actually calculates the estimate.

honestly this looks super useful, especially since you can compare mixed breeds side by side. one thing i'd love to see is a way to log your puppy's actual weight over time and get a projected adult weight that updates as they grow, basically recalculating the estimate with each new entry so it's more accurate than just using the birth weight.

Love that you show the methodology behind the estimates, that kind of transparency is rare. One thing that would be really helpful is letting me save my puppy's data and track their actual weight over time against the predicted curve, so I can see if they're trending above or below the estimate as they grow.
