Vet Approved Guide: How to Calculate Your Dog’s Healthy Weight in 2025 🐾🐶

By Dr. Duncan Houston BVSc

Maintaining your dog's healthy weight is crucial for their overall well-being and longevity. 🐾 Overweight or underweight dogs are at risk for various health issues, including joint problems, diabetes, and heart disease. Let's explore veterinarian-approved methods to assess and calculate your dog's ideal weight in 2025. 📏

🔍 Step 1: Determine Your Dog’s Body Condition Score (BCS)

The Body Condition Score (BCS) is a visual and tactile assessment tool used to evaluate a dog's body fat. It's typically measured on a 9-point scale:

  • 1-3: Underweight
  • 4-5: Ideal weight
  • 6-7: Overweight
  • 8-9: Obese

To assess your dog's BCS:

  • Ribs: You should be able to feel (but not see) your dog's ribs without excess fat covering.
  • Waist: Viewed from above, your dog should have a visible waist behind the ribs.
  • Abdominal Tuck: From the side, the abdomen should tuck up behind the ribcage.


📐 Step 2: Calculate Your Dog’s Ideal Weight

Once you've determined your dog's BCS, you can estimate their ideal weight using the following formula, developed by researchers at the University of Liverpool and Royal Canin:

  1. Subtract 5 from your dog's BCS.
  2. Multiply the result by 10.
  3. Add 100 to the result.
  4. Divide 100 by the result from step 3.
  5. Multiply this number by your dog's current weight.

Example: For a 50-pound dog with a BCS of 9:

  1. 9 - 5 = 4
  2. 4 x 10 = 40
  3. 40 + 100 = 140
  4. 100 / 140 = 0.714
  5. 0.714 x 50 lbs = 35.7 lbs

So, the target weight for this dog would be approximately 35.7 pounds.

⚖️ Step 3: Monitor and Adjust

Regularly monitor your dog's weight and BCS, adjusting their diet and exercise as needed. Consult your veterinarian for personalized advice, especially if your dog has health conditions or if you're unsure about their ideal weight.
