Scenario: Calculating BMI for a 40 lb Labrador Retriever
Find the BMI and body condition for a 40-pound Labrador with a 24-inch body length.
Step 1: Identify measurements: Weight = 40 lbs, Body Length = 24 inches.
Step 2: Square the body length: 24² = 576.
Step 3: Divide weight by squared length: 40 / 576 = 0.0694.
Step 4: Multiply by 703: 0.0694 × 703 = 48.8.
Step 5: A BMI of 48.8 for this Labrador suggests the dog is in the overweight category. Ideal BMI for dogs is typically 35—45 depending on breed.
