How to Use This Tracker
Enter Your Vet's Plan
Type in your pet's name, current weight, and the target weight your vet recommended. Add the start date and the date your vet suggested for reaching the goal.
Weigh Weekly
Pick the same day each week. Use the same scale on the same surface. Weighing before breakfast gives the most consistent numbers. Log the weight and any notes.
Watch the Chart
The line chart shows your pet's trend over time. The milestone bar fills up as you get closer to the goal. Green means on track, yellow means slowing down.

Common Mistakes and Tips
Weighing at Random Times
A pet's weight can swing by a pound or more depending on when they last ate or drank. Always weigh at the same time of day, under the same conditions. Morning, after a bathroom break but before food, works best for most pets.
Expecting Fast Results
Safe weight loss for pets is about 1-2% of body weight per week. A 70-pound dog should lose about 0.7 to 1.4 pounds weekly. Slower is often healthier. If your pet is losing faster, check with your vet.
Not Measuring Food
Guessing portions is one of the biggest reasons weight plans fail. Use a digital kitchen scale to measure food by weight, not volume. A cup of kibble can vary by 20% depending on the brand and piece size.
Skipping Weeks
Even if you think the number won't change, log it. Gaps in data make it hard to see the real trend. A flat line for two weeks might mean it's time to adjust the plan.
Ignoring Small Gains
A small bump up after weeks of progress is normal. Look at the overall direction, not a single reading. But if weight climbs for three weeks in a row, it's worth a call to the vet.
Forgetting Treats Count
Treats add up fast. A few small biscuits can be 10-15% of a small dog's daily calories. Track treats in the notes section so you can spot patterns if weight loss stalls.
Example: Buddy's 12-Week Plan
Buddy is a 5-year-old Labrador. His vet wants him to go from 72 pounds to 60 pounds over 12 weeks. That's about 1 pound per week, which is a healthy rate for a dog his size.
Week 1: Buddy weighs in at 72.0 lbs. The plan starts.
Week 4: Down to 68.5 lbs. The chart shows a steady decline. The milestone bar is at 29%. Buddy gets a "Quarter Way There" celebration.
Week 8: At 64.0 lbs. Halfway to the goal. The owner prints a report for a vet check-in. The vet says the pace is good and keeps the plan the same.
Week 12: Buddy hits 60.5 lbs. Close enough to the target. The vet is happy and switches to a maintenance plan.
This kind of steady progress is exactly what this tracker is built to show. Without writing it down, it's easy to forget where you started and how far you've come.
Questions Pet Owners Ask
How often should I weigh my pet?
Once a week is ideal. Pick the same day and time, and use the same scale. Weighing after a morning walk but before breakfast gives the most consistent results.
What if my pet's weight goes up instead of down?
Small fluctuations are normal. Look at the overall trend over 3-4 weeks rather than a single reading. If weight keeps going up, check with your vet about adjusting portions or exercise.
Can I track more than one pet?
Yes. Use the "New Pet" button to create a separate tracker for each animal. Each pet's data is saved independently in your browser.
How do I share this with my vet?
Click the "Print Report" button to get a clean, printable summary with the weight chart and all logged entries. You can also save it as PDF from your browser's print dialog.
What happens to my data if I clear my browser?
All data is stored locally in your browser. Clearing browser data will remove your pet profiles. Use the "Export Data" button to save a backup file you can import later.
