Hi Product Hunt! 👋🐾 Every new puppy parent wonders: "How big will my dog actually get?" Most online calculators use lazy linear math (like multiplying weight at 16 weeks by 2). But canine biology doesn't work that way—a toy breed finishes growing around 9 months, while a giant breed grows for up to 2 years! I built PupWeight (https://pupweight.com) to solve this using published canine pediatric growth curves (Gompertz-logistic models) and official AKC breed standards. Key highlights: • Interactive real-time sliders (toggle between lbs & kg) • Visual growth curve showing where your pup sits in the healthy corridor • Growth plate closure timelines and veterinary feeding guidance • 100% free, ad-free, and requires zero signups I'd love to get the community's feedback on the UI and hear which dog breeds you'd like added next!
