Pet Weight Tracker

Log your pet's weight over time and see it charted against the healthy range for its breed or species. The tool alerts you when readings trend over or underweight.

How It Works

Each time you weigh your pet, log the value and date. All data is stored locally in your browser (nothing is sent to a server), so your history is private and persists between visits.

Healthy Range Bands

When you pick a species and breed, the tool loads a typical healthy adult weight range for that breed. This range is shaded as a green band on the chart, so you can see at a glance whether your pet sits inside, above, or below it. If your breed isn't listed, choose Other / Custom and enter your own target range (your vet can advise a realistic goal).

Status Categories
StatusMeaning
UnderweightBelow the healthy range for the breed
IdealWithin the healthy range
OverweightUp to ~15% above the healthy maximum
ObeseMore than ~15% above the healthy maximum
Trend Alerts

Beyond a single reading, the tool looks at your last few entries. If weight is steadily climbing above or dropping below the healthy range, you'll get a trend alert — an early sign to adjust diet, activity, or book a checkup before it becomes a bigger problem.

Disclaimer: Breed weight ranges are general guidelines — healthy weight varies with age, sex, frame size, and neutering. This tool is for informational tracking only and is not a substitute for veterinary advice. Body condition score, assessed by a vet, is the most reliable measure.
