Dog Weight Calculator

Reading the trend

A single weight is a starting point. Several dated measurements let you look back at what was recorded, instead of relying on a remembered number. Use the same scale and similar measuring conditions when possible, and check that each entry uses the intended unit. A change of scale or a mistyped unit can create an apparent jump that does not describe a real change in your dog.

Direction matters more than speed

Look across the history rather than treating the difference between two entries as a verdict. The summary compares the earliest measurement with the latest and states the dates and number of observations. It describes an increase, decrease, or no net change; it does not grade the direction as good or bad. Measurements on only one date do not establish a change over time.

When a change is worth a vet visit

If a change is unexpected or unexplained, contact your veterinarian rather than using this line to decide whether it is safe. AAHA includes unexplained weight loss or gain among signs that need veterinary attention. Bring the dated entries and any observations about appetite, activity, or measuring conditions. This page cannot determine the cause or urgency of a change.

What this page will not tell you

The tracker does not calculate an ideal weight, diagnose body condition, or recommend a food change. Adult size, if saved in a profile, is background information and does not place a point in a healthy-weight band. This chart draws actual observations without a growth forecast. Adult-weight estimation now lives only on the puppy growth calculator; the two tools share local dog profiles and unit conversions, not a prediction line.

Your weight chart

The horizontal axis represents measurement dates, spaced by elapsed calendar time. Two dates a month apart occupy more space than dates one day apart. The vertical axis shows weight in the selected chart unit and starts at zero, so a small recorded difference is not magnified by a cropped baseline. The line simply joins your entries; it does not fill in measurements for the days between them.

Use “Chart and list unit” to switch the display between kilograms and pounds. This converts the view without rewriting saved values. Internally, each measurement keeps a kilogram value plus the unit used when it was entered. The conversion uses the exact definition of one pound as 0.45359237 kilograms; displayed values are rounded for readability.

With no records, you see an empty chart and an empty measurement list. One record produces a single point. Entries on the same date can overlap on the chart, but each remains a separate row with its own delete action. The newest entry on the latest measurement date determines the latest-weight display. Deleting it reveals the next applicable observation.

Export and share

Weight records are saved in this browser on this device. They are not sent to a server or synchronised to an account. Export a copy if you want to open the history elsewhere, send it to your veterinarian, or keep it outside the browser. Choose the intended dog profile before downloading; a CSV contains that dog’s records only.

CSV gives you one row per saved measurement with its date, weight, and original entry unit. It includes the complete history, even when the on-screen list is showing only its first rows. You can open the file in a spreadsheet or attach it to a message yourself. Exporting does not send a message or create a public sharing link.

Print records opens the browser’s print dialog with the recorded chart and the full measurement list. You can print or save a PDF using the browser’s options. Long histories may span several pages; rows beyond the on-screen “Show more” limit are still included. The chart is a visual overview, while the list supplies exact dates and displayed weights.

Keep a restorable backup as well. CSV is for reading and sharing, not importing back into PupSaga. Use the JSON backup controls in My Dog to preserve profiles, saved calculations, and measurements in the format this site can restore. Clearing site data, changing devices, or losing browser storage can remove local records. There is no cloud copy to recover, so export before making those changes.
