Calculate your pet's ideal weight and body condition with personalized recommendations
Maintaining a healthy weight is crucial for your pet's overall health and longevity. Overweight pets are at higher risk for diabetes, joint problems, heart disease, and reduced life expectancy. This calculator helps you assess your pet's current weight status and provides guidance on achieving and maintaining an ideal weight.
| Condition | Visual Signs | Touch Test | Action Needed |

| Ideal Weight | Waist visible, ribs not showing | Ribs felt easily with slight pressure | Maintain current routine |
| Overweight | Waist barely visible, rounded belly | Ribs hard to feel, fat layer present | Reduce portions, increase exercise |
| Obese | No waist, sagging belly, fat deposits | Ribs not felt, thick fat layer | Vet-supervised weight loss plan |
Different breeds have different ideal weight ranges. Small breeds typically weigh 5-25 lbs, medium breeds 25-50 lbs, and large breeds 50-100+ lbs. Cats generally range from 8-12 lbs depending on breed.
Puppies and kittens need more calories for growth. Adult pets (1-7 years) need maintenance calories. Senior pets (7+ years) often need fewer calories due to reduced activity and slower metabolism.
Active pets burn more calories and can maintain higher food intake. Sedentary indoor pets need fewer calories. Working dogs and outdoor cats typically need 20-40% more calories than inactive pets.
Spayed and neutered pets have 25-30% lower calorie needs due to hormonal changes affecting metabolism. Adjust portions after surgery to prevent weight gain.
Measure food portions accurately using a measuring cup or kitchen scale. Follow feeding guidelines on pet food labels based on ideal weight, not current weight. Divide daily portions into 2-3 meals to maintain steady energy and prevent overeating.
Limit treats to 10% of daily calories. Choose low-calorie options like carrots, green beans, or small pieces of lean meat. Avoid table scraps and high-fat treats. Use portion of regular food as training rewards instead of extra treats.
Dogs need 30-60 minutes of daily exercise through walks, play, or swimming. Cats benefit from 15-20 minutes of interactive play with toys. Gradually increase activity for overweight pets to avoid injury. Make exercise fun and consistent.
Weigh your pet weekly during weight loss, monthly for maintenance. Track body condition score changes. Healthy weight loss is 1-2% of body weight per week. Consult your vet if weight doesn't change after 4-6 weeks of diet and exercise adjustments.
