Puppy Weight Chart Spreadsheet

Weekly weighing is the single most important data point in the first year of life with a new puppy. Not because every gram matters, but because the trend matters. A puppy gaining steadily through the puppy growth curve is doing what puppies do. A puppy whose curve flattens, dips, or rockets up has a story to tell, and that story almost always shows up in the weights before it shows up in any other symptom.

Most owners weigh sporadically and lose the data. The Puppy Weight Tracker turns 24 weekly weights into a trend you can actually read.

What this document does:

It tracks weekly weights from go-home day through 12 months in a single Excel workbook with live formulas. Enter the date and weight each week. The spreadsheet calculates the weekly gain (current weight minus previous week) and the percent gain (gain as a fraction of the previous weight). A total gain summary at the bottom shows growth from first weigh-in to current.

The tracker is built to live on a phone or laptop. Weekly weighing takes 30 seconds. Entering the weight takes 5 seconds. The math happens automatically.

What is included:

• Excel workbook (.xlsx) with live formulas for weekly and percent gain
• Dog identification section with name, date of birth, breed, expected adult weight, weight unit (default lb), vet, sex, and microchip
• 24-row weekly weigh-in log with columns for date, age in weeks, weight, weekly gain, percent gain, body condition score (1-9), and notes
• Total gain summary at the bottom of the log with auto-calculated growth from first weigh-in
• Companion document to the Puppy Growth Chart for benchmarking against expected ranges by adult-size category

Format and how it works:

Excel workbook (.xlsx) with live formulas plus a printable PDF version. The .xlsx works in Excel, Apple Numbers, and Google Sheets. Most owners keep the spreadsheet on a phone or laptop and enter the weight right after the weekly weigh-in. The notes column is the part owners actually use most: anything unusual that week (a vaccine, a vet visit, a food change, a new stress) goes in the notes column so the weight trend has context.

For very young puppies (under 12 weeks) or large litters being raised by a breeder, the Puppy Vaccination Schedule workbook (also in this kit) is the better companion. The Weight Tracker is built for owner-side weekly weighing from go-home onward.

Why this version is different:

Static weight charts on the internet do not calculate trends. They ask you to do the math and remember the previous week's value. This tracker does the math. The weekly gain and percent gain columns auto-update the moment you enter the current weight. The total gain summary gives you the full-growth view at a glance.

The body condition score column is the part that veterinary professionals will recognize. The 9-point body condition scale is the standard tool vets use to assess whether a dog is underweight, ideal, overweight, or obese. Capturing it weekly produces a longitudinal record most owners cannot otherwise reproduce.

Who this is for:

For new puppy owners who want weekly weight tracking that actually surfaces trends. For owners of large and giant breeds where growth rate matters for orthopedic health. For owners of small and toy breeds where small weight changes are proportionally larger and easier to miss without a tracker. Pairs with the Puppy Growth Chart (expected ranges by size category) and the Vet Visit Tracker (visit-level weight capture).
