Why don't we use a mathematical BMI formula for dogs?
Because dog breeds vary drastically in shape, size, and muscle mass (e.g., a Greyhound vs. a Bulldog), a simple weight-to-height ratio is highly inaccurate. Veterinarians rely on the Body Condition Score (BCS) instead.
What is an ideal BCS score?
On a 9-point scale, a score of 4 or 5 is considered ideal. Scores 1-3 indicate the dog is too thin, while scores 6-9 indicate the dog is overweight or obese.
How can I tell if my dog's ribs have the right amount of fat?
When you run your hands along your dog's side, it should feel like the back of your hand. If it feels like your knuckles, they are too thin. If it feels like the palm of your hand, they are too heavy.
