Puppy Weight Estimator

What it does

Puppy Weight Estimator is a free web tool for puppy parents. Enter your puppy’s age, current weight, and expected size to get a practical adult-weight range, then explore a simple growth curve, breed references, and the assumptions behind the estimate. It is built for everyday planning—not diagnosis or veterinary advice.

Free puppy weight calculator and estimator. Enter age, current weight, and size to understand likely adult weight, growth patterns, and next steps.

Get a calm, useful estimate of your puppy’s likely adult weight, then see the growth curve behind the range. Growth is a curve. We show the range and the context so you can make sense of what you see. Add a few details to see a planning range for your puppy’s adult weight. Medium breeds usually keep filling out through the first year. Use this as context, not a diagnosis. A puppy weight calculator is most useful when it answers a practical question without pretending to know the future. You may be choosing a crate, planning a travel setup, comparing harness sizes, or wondering whether your puppy is likely to become a small, medium, or large adult dog. A range gives you a useful direction…from puppyweightestimator.com

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
