How Pet Weight Tracker Works

Is Your Pet at a Healthy Weight?
Over 50% of dogs and cats in developed countries are overweight or obese. Just like in humans, excess weight leads to serious health problems: diabetes, joint disease, heart disease, and shorter lifespans. Research shows that lean dogs live an average of 2.5 years longer than overweight dogs.
Body Condition Score (BCS)
Veterinarians use a 9-point Body Condition Score to assess pet weight. A score of 4–5 is ideal. Here is how to check at home:
- Ribs: You should be able to feel individual ribs with light pressure, but not see them
- Waist: When viewed from above, there should be a visible waist behind the ribs
- Tummy: From the side, the abdomen should tuck up behind the ribcage
Healthy Weight Ranges by Size
Weight ranges vary dramatically by breed. A healthy Chihuahua weighs 3–6 lbs, while a healthy Great Dane weighs 110–175 lbs. The breed size selector in our tool gives you a general range, but your veterinarian can provide the most accurate target weight for your specific pet.
Weight Loss Tips for Pets
Never crash-diet a pet. Aim for 1–2% body weight loss per week. Measure food precisely (do not eyeball it). Cut treats to less than 10% of daily calories. Replace high-calorie treats with vegetables like green beans or carrots. Increase exercise gradually. And always consult your vet before starting a weight loss plan.
When to See the Vet
If your pet loses weight unexpectedly, gains weight rapidly despite normal portions, or you notice changes in appetite or thirst, schedule a vet visit. Sudden weight changes can indicate thyroid issues, diabetes, or other medical conditions.
Frequently Asked Questions
How do I know if my pet is overweight?
Use the rib test: place your hands on your pet's sides. You should feel individual ribs with light pressure. If you need to press hard, your pet may be overweight. Also look for a visible waist from above and a tucked tummy from the side.
What is a Body Condition Score?
BCS is a 9-point scale veterinarians use to assess body fat. 1 is emaciated, 4–5 is ideal, and 9 is severely obese. You can learn to assess BCS at home with practice.
How often should I weigh my pet?
Weigh adult pets monthly. Weigh puppies and kittens weekly during their first 6 months. If your pet is on a weight management plan, weigh them weekly.
Is my pet's weight data stored anywhere?
Your weight history is stored only in your browser's local storage. It never leaves your device. No account needed and no data is sent to any server.
How much weight can my pet safely lose per week?
Aim for 1–2% of body weight per week. For a 50 lb dog, that is 0.5–1 lb per week. Faster weight loss can cause liver problems, especially in cats.
