🎯 Assessing Your Pet's Weight

Body Condition Scoring System

📏 9-Point Body Condition Scale

Underweight (1-3)
  • Ribs: Easily visible and felt with no fat cover
  • Waist: Severe abdominal tuck, prominent waist
  • Overall: Bony prominences obvious, minimal muscle mass
Ideal Weight (4-5)

  • Waist: Visible when viewed from above and side
  • Overall: Hourglass shape, abdomen tucked up
Overweight (6-7)
  • Ribs: Difficult to feel under fat layer
  • Waist: Barely visible, rounded appearance
  • Overall: Some abdominal fat, less defined waist
Obese (8-9)
  • Ribs: Cannot feel under heavy fat layer
  • Waist: No visible waist, may bulge outward
  • Overall: Heavy fat deposits, distended abdomen

Hands-On Assessment Technique

🤲 Physical Examination Steps

Rib Check
  • Hand position: Place thumbs on backbone, fingers spread
  • Light pressure: Should feel ribs like knuckles under skin
  • Ideal feel: Like the back of your hand
  • Too thin: Feels like knuckles with no padding
  • Too heavy: Cannot feel ribs through fat layer
Visual Assessment
  • Side view: Look for abdominal tuck-up
  • Top view: Should see hourglass waist shape
  • Movement: Observe gait for labored breathing
  • Activity level: Note changes in energy
  • Compare photos: Track changes over time

🥗 Diet-Based Weight Management

Caloric Needs and Deficit Creation

🧮 Weight Loss Calculations

Determining Target Weight

Calorie Calculation Formula
  • Target RER: 70 × (target weight in kg)^0.75
  • Weight loss factor: RER × 0.8-1.0
  • Safe deficit: 20-30% below maintenance
  • Minimum calories: Never below 60% of maintenance
  • Regular adjustment: Recalculate as weight drops
